Details of squamous cell carcinoma skin cancer

 What is squamous cell carcinoma skin cancer ?
Normally, skin cancer squamous cell carcinoma is a type of skin cancer due to exposure to ultraviolet rays of sun damage to the skin and the long-term. Also skin cancer squamous cell carcinoma, and gradually spread, has the ability to diffuse into tissues such as the eye close to the affected area. Not be able to spread to distant parts of the body even if the cancer is treated in time.The only way to make sure the best, whether the growth of skin cancer is to go for a biopsy. The process involves the removal of a small portion of the skin. Then, the pathologist will analyze it under the microscope in the medical room.Please note that this is not a process to remove the cancer biopsy. I work towards the take-off the tip of the cancer by itself.

TYPES OF SKIN CANCER

It tends to heal skin biopsy is performed and in some cases through a cancer grows. However, this does not indicate that the cancer has been completely removed. Here, the cancer is covered with a blanket of skin only. In that case, you can be cancer is not completely removed, it gets deep into the skin and spread to the internal organs of the human body leading to further human deaths.Skin cancer is squamous cell carcinoma is one of the most common forms of skin cancer are known. It is more than 25,000 new cases, all is true that is reported annually in the U.S. alone is shocking. Cancer, squamous cells derived from the upper part of the skin that is most of the time.
All cases of squamous cell carcinoma skin cancer is not serious. If it is early detection and rapid processing, one you can easily survive this disease. If not treated properly, this disease you can prove to be very difficult to become even disfiguring treatment.
Under the skin cancer is squamous cell carcinoma can have several causes. Some of these are as follows.
Frequently, i) is the long exposure to harmful sun rays. As a result of this severe skin damage, and ultimately skin cancer has developed into squamous cell carcinoma.
Performed by ii) Sun damage to the skin is most responsible factor for the development of this type of cancer. Face is exposed to the sun, most are spread to other parts of the body cancer.
Human skin ⅲ) light has a greater risk of developing squamous cell carcinoma skin cancer.

 Already ⅳ), I have been told people who have developed this cancer and to develop more.Chronic exposure to the sun is the main cause of this type of cancer. Tumor, invade the parts of the body like face, neck,  hands, shoulders, arms, back, etc., such as those exposed to more sun. Edge of the ear and the lower lip is more vulnerable to these cancers.
Squamous cell carcinoma skin cancer also, due to the particular type of injury as the site to be exposed to hazardous chemicals, such as arsenic and some scratches, burns, long existing scratches, petroleum by-products, such as X-rays and may develop. Also decrease the immune, is one of the main reasons for the spread of this type of cancer. Detected and treated early to stay away from the possibility of damage and full recovery.
Types of skin cancer:-
And malignant melanoma:-A type of skin cancer, malignant melanoma can (nevus cells) may become cancerous melanocytes to make melanin, to do with color or skin (pigment cells), the cells of the mole. In men aged 60, but occurs most commonly in women in their 70-year-old, it is not often that occurs in middle-aged young people aged 30 to 50 years. The most common site of origin but the soles of the feet, may occur in various parts of the body and face, and nails.

It is said about the cause of malignant melanoma can occur, although it is not yet well understood, from the fact that many developing white race, and are involved in the ultraviolet. I can easily, such as it is believed that the soles of the feet and nails, to a place where you are always inspired, and are also related to stimulus from the outside also. Clinical symptoms of malignant melanoma can be divided into (subtypes) of the four major groups. In some cases, however, can not be classified clearly. 
1.Superficial spreading melanoma
In many cases, it is considered more likely to occur from the cells of moles, it can be anywhere in the body. Disease is common in Caucasian type, in recent years, the Japanese have also increased. Stains can be seen slightly raised, with irregular boundary as well, color is a mixture of shade-like plaques. Many 40-year-old to 50 years old, of tumor growth (cancer) is relatively slow.

2.Lentigo maligna melanoma 
Many elderly people can face and neck, and dorsum of the hand, the boundaries of dark brown mottled pigmentation flat also comes out in irregular color. It is said the probability of slow growth, healing is high.

3.Lentigo melanoma type terminal 

The most common disease in Japanese type occurs claw back and palms, feet and toes of the Lord. In the beginning of blackish-brown stains can be, or become mottled color or darker part. Or ulcers may be able to progress and uplift. You may be able to have vertical black stripes on nails, cracks spread across the nail. Often seen in later 60s, I noticed that there are many from well underway. I It is not uncommon to find in the state of early lesions in the diagnosis of dermoscopy law recently.

4.Nodular melanoma 
Often grow rapidly from the beginning, it occurs anywhere in the body. Generated from small tumor nodules (hard lump), color is black and shades is now concentrated on the whole mixed. It is more common in people aged 40 to 50 years. Melanoma tumor growth (cancer) is fast.

Malignant melanoma, it is said there is a prodrome or symptoms of the early stages of cancer, five characteristics of ABCDE shown below will help in the detection. When referring to these five points, the higher the possibility of malignant melanoma. In addition, as the main feature, changing inflamed ulcer ④, scab-like bleeding or ⑤, sensory ⑥, ⑦ lesion diameter of change in the size of 6 ①, color change ②, changes in the shape ③, as other features mm and useful points greater than that for early detection of malignant melanoma. When usually, be careful to observe, was anxious that a doctor as soon as possible, but I lead to early detection.  
Symptoms of early malignant melanoma:-
    Is asymmetrical forms Asymmetry: A
    Border of irregularities is border irregularity is jagged: B. There is a bleed through of color.
    C: Color variegation color is not uniform. There is a color shading.
    Is greater than or equal to 6 mm diameter is 6 mm Diameter greater than: D
    E: expansion of the size Enlargement or evolution of color change, shape, or symptoms, changes in color and shape, the symptoms 

SYMPTOMS OF SKIN CANCER

 Inspection and diagnosis of malignant melanoma:-

Malignant melanoma, it is necessary to diagnose the overall clinical symptoms dermatologists. If is difficult to diagnose, the pathological examination examined under a microscope to take tissue from the affected area has been carried out, just seen skin biopsy Add the knife directly to malignant melanoma, it is possible to encourage the transition once because it had been, and it is not actively being conducted today. If it is difficult to diagnose from clinical symptoms, the total excision biopsy to remove the entire tumor. There is also a reference to it the value of the tumor marker blood tests and much more. Tumor markers because they increased in fairly advanced stage, I can not say will be useful in early diagnosis, however. In order to examine the transfer of organs, such as lymph nodes and sometimes performed ray image diagnosis X, ultrasound (echo), CT, MRI, such as PET. 
Ultrasound (echocardiography)
    How to shed body ultrasound to examine the state of the body in its repercussions. To predict the thickness is an important indicator of the degree of progression (cancer that occurred first) primary tumor, such as to help locate the lymph node metastasis. 
CT, MRI examination
    Depicts the interior of the body using a line X, CT, examine the extent of the cancer and the surrounding transition prior to treatment. MRI uses a magnetic field. When using a contrast agent may occur allergies. Tell your doctor you need people who have experience of iodine allergy. 
PET
    By injecting radioactive glucose solution, taking the distribution of its incorporation, a check is made to detect the cancer cells throughout the body. 
Staging of malignant melanoma (stage)
In words that indicate the degree of progression of cancer, stage of disease and is used as it is also called English stage. Often, the word "stage" in the description, such as is used. Roman numerals are used, on the stage, in malignant melanoma, it has been classified as stage Ⅰ, stage Ⅱ, stage Ⅲ, stage Ⅳ. The stage is substantially determined by whether the thickness of cancer metastasis to other organs or lymph nodes. Method of treatment is determined by the stage of the disease have been diagnosed.

     Esophageal cancer: description of the disease
                      And esophageal cancer
Esophageal cancer that can be, many are squamous cell carcinoma arising from the esophageal mucosa. As a special esophageal cancer is Barrett adenocarcinoma,adenosquamous carcinoma,basaloid carcinoma, endocrine cell carcinoma, undifferentiated carcinoma, and malignant melanoma. Can be cured by surgery endoscopic If you can find early in is possible, there is a feature that causes the lymph node metastasis from an early stage in comparison with colon cancer and gastric cancer, when compared to these cancers, the grade I say high cancer. It is also an area that can cause extensive lymph node metastasis is the neck, chest and abdomen, is causing a high degree of malignancy. Total power, including not only doctors, but also other co-medical staff such as nurses, laboratory technicians and rehabilitation is an integral part of the medical esophageal cancer.
What many people do?
Esophageal cancer are over the age of 50 Mature much, it is a disease many men at a ratio of 9:1. In addition, it is said drinking history and smoking history is closely related with the development of esophageal cancer, it has been said that people with a high risk of both history and drinking habits, especially smoking history. It is also considered to be high risk, such as some people are constitutionally turns red immediately after drinking alcohol.
Symptom
Initially be asymptomatic in most cases, many cancers are the same for esophageal cancer. Becoming a high probability of pain and discomfort, dysphagia that gradually becomes larger as was tingling when swallowed food comes out. However, it may not even be aware of the symptoms can be quite large and it is important endoscopy.
Inspection
Esophageal cancer treatment is selected on the basis of highly accurate diagnosis progression, including imaging. Below, we describe the detailed examination of esophageal cancer.

Fig 1 X-ray view

1.X-ray angiography esophagus
    X-ray angiography is finding the (early cancer) is quite difficult cancer mucosa, visualization of esophageal cancer invading the submucosa or more cancer is relatively easy, the presence of esophageal cancer can be diagnosed. Information obtained from many X-ray contrast, not only the diagnosis of progression range and extent (diameter), depth of invasion and occupying a certain place of the stenosis site, the stationary circumferential tumor size can be determined (Figure 1).
2.Endoscopy esophagus
Recently, a more detailed observation was made possible by the development and expansion of visual inspection and precision-weighted images, such as endoscopic band filters (Narow band imaging :: NBI) is applied to a narrow, a combination of these. Site of esophageal cancer, disease type, size, spread, information obtained from endoscopy, which is presence or absence of invasion depth of the lesion frequently, it is possible to obtain a pathological diagnosis by biopsy to collect tissue . Said the discovery of cancer is a disease mucosa adaptation of endoscopic resection is an important examination that can not be lacking. In addition, we also observe in detail the larynx and pharynx as well as the stomach and duodenum, we are also committed to the discovery of cancers. In order to undergo endoscopy comfortably without pain, in our department, we are doing a combination of sedative.
3.Esophageal endoscopic ultrasound

Fig 2 Endoscopy esophagus view

Tests that can not be essential to the diagnosis of lymph node metastasis and abdominal mediastinal diagnosis and depth of invasion of esophageal cancer, (EUS) is performed followed by endoscopy normal Endoscopic ultrasonography endoscopic ultrasonography. There are two tests to be used more ultrasonic probe integral with the ultrasonic probe is incorporated into an endoscope, biopsy forceps through the endoscope hole in the endoscopic ultrasound. I have observed using a 20MHz frequency from 5MHz. At present, I have been viewed as a means to obtain the most detailed information.
4. CT, MRI examination
Outer membrane invasion and lymph node metastasis to other organs adjacent ie local evolution of esophageal cancer, (CT) is useful in the diagnosis of distant organs such as the liver and lung metastases and Computed tomography. CT examination at the time of enforcement detailed information can be obtained from the vessel lumen and tumor imaging is by intravenous injection of contrast agent at high concentrations. Also, now allows the development of the MDCT column 64, a more precise diagnosis is performed in a short time. About the presence or absence of lymph node metastasis and invasion of esophageal cancer aortic tracheobronchial invasion and progression will be important information in determining the course of treatment, including surgery.
(MRI) is a test image to be configured as a digital tomographic image by calculating the distribution of the electromagnetic resonance computer that is out of the organism Magnetic resonance imaging. Is superior in terms of image obtained of sagittal and coronal cross-section not. MRI is a useful test image and adjacent organ invasion in the outer membrane of tumor invasion and lymph node metastasis.Others have been enforced as ultrasound examination is also an important external expression.

5.PET-CT
A new test method called PET (positron emission tomography radiation) has been paid attention recently. This is a way that can be detected with high sensitivity that is active metabolism of cancer cells than normal cells. By combining There was not using the test CT, MRI, and ultrasound, only inferred from the size and shape of lymph node metastasis until now, PET examination and inspection CT, lymph node metastasis little was hard to find until now We were able to discover and distant metastases.It is determined that a comprehensive picture of these test results, we make a proper treatment plan based on the age and general condition, such as organ function. The Company has enforced to
the extent possible If it is possible to visit the day without eating during the initial visit to our hospital, these checks, we are committed to rapid diagnosis.
Treatment
Considering the state of esophageal cancer, and the general condition, the treatment of esophageal cancer have been made to the following treatment.
1.Thoracic esophageal cancer surgery
Esophagus is divided into three cervical esophagus, thoracic esophagus, and abdominal esophagus. Because there are a lot of things that can thoracic esophageal cancer, it is a surgical procedure that is performed most. Adaptation is a cancer that has invaded the wall invasion depth deeper than the submucosa. Adaptation cases deviate from esophageal cancer invading the trachea and large blood vessels, such as the cases that have spread to the lungs or liver. Thoracic esophageal cancer surgery is not only breast surgery with cancer. Surgery three regions chest, abdomen, and neck is performed.We performed the resection of thoracic esophageal cancer, including breast operations.Food in the stomach to create a new path in the operation of the abdomen (stomach tube created).We do the anastomosis of the cervical esophagus and gastric tube was lifted up to the neck in the neck. Surgery for esophageal cancer is not the only resection of the cancer. It is important that the lymph nodes along the resection (lymph node dissection). Possible that there is a lymph node metastasis in thoracic esophageal cancer is not only the chest, abdomen and neck as well. Lymph node dissection is performed three regions cervical, thoracic, abdominal and therefore. Pathway reconstruction to lift up the neck There are three gastric tube.

(Through a subcutaneous route) route chest wall before
(Between the sternum and the heart) retrosternal route
(There was a part of the original esophagus)vertical path after
We have been selected according to the case because there each with its own advantages and limitations. Immediately after surgery are managed in the intensive care unit and return to the ward the day after state permitting. We will prevent complications of pneumonia you for the gait training from an early stage.Meal begins around 1 week after surgery. Hard to swallow at first, starting from the diet soft banana and taro easy to choke, the discharge will be happy to eat gruel. I will explain later in the outpatient observation results and pathology of the resected esophageal cancer with surgery prior to discharge. Whether the cancer had invaded to a depth how microscopic examination, the specific content is about the presence or absence of lymph node metastasis. Recently endoscopic surgery, using minimally invasive surgery in order to improve esophageal cancer, performed by inserting an endoscope into the chest or abdomen, the laparoscope has been performed and thoracoscopy. At our institution, depending on the progress of esophageal cancer, surgery is performed under endoscopic esophageal cancer aggressively.
2.EMR / ESD esophagus
It is said that esophageal cancer is early detection and disease, difficult to treat. But you can be discovered in the early stage of the cancer, the curative endoscopic resection is less burden on the patient in the same way as gastric cancer and colorectal cancer. Treatment is to resect the esophageal mucosa, including cancer of the esophagus using an endoscope inserted orally and endoscopic resection. Mucosal epithelium, lamina propria, muscularis mucosa, submucosa, and muscularis propria from the inside, the thickness of the outer wall of the esophagus is covered with about 4mm in most outer membrane.Adaptation of endoscopic resection is determined by the depth of invasion and the circumferential wall superficial primarily. Wall with respect to depth of invasion, infiltration cancer is cancer of the mucosa to the lamina propria. Because there is no risk of lymph node metastasis why. Zhou is with respect to superficial lesions less than 2 laps / 3.

 Because it is difficult to pass through diet and cicatricial stenosis of reason in the process of healing is resected to near the whole circumference. Method of endoscopic resection can be classified into two broad. There endoscopic submucosal dissection is (ESD) and endoscopic mucosal resection (EMR).
EMR is a way of sucking the esophageal mucosa resection including lesions in the cap that is attached to the distal end of the endoscope tube and dedicated. Than the initial EMR is now performed on esophageal cancer in our hospital, he has been carried out using a special tube, which was developed by Professor Hiroyasu Makuuchi. I've been treating esophageal cancer more than 800 cases to date. Can be performed safely and can exhibit still better results, I believe good therapy. ESD is a method of esophageal mucosal resection in bulk, including cancer of the esophagus using a special knife. In this hospital we have decided to adapt depending on the case.Cancer and other smoking as a risk factor for esophageal cancer, drinking, men, ENT area is well known. Find out more cases of cancer mucosa, In our hospital, we are actively working to esophageal cancer screening test so that it can be curative endoscopic resection.
3.Chemoradiotherapy
 The method of treatment other than resection of the esophagus, there is a radiation therapy and chemotherapy (anticancer drug treatment). Higher therapeutic effect by combination chemoradiotherapy called what was a combination of these two effects can be expected synergistic additive, than they do chemotherapy or radiation therapy alone.If it is not possible to determine from such surgery useless due to a history degree and progression of esophageal cancer is one of the treatment carried out for the purpose as well as curative surgery. It is the treatment of choice even if you do not want surgery or even surgery.

For fairly high degree of invasiveness, as well as late effects occur in addition to side effects, it does not say the treatment and pain but never less. In addition, by chemoradiation treatment, the disease may relieve the symptoms can be achieved a reduction in tumor metastasis and recurrence for such.According to the information service, such as cancer by National Cancer Center, it is reported that in the 5-year survival rate comparable to surgery. 

4.Esophageal stent insertion technique
Surgical stent insertion has been done for the purpose of securing the lumen when the occluded blood vessels, trachea, bile duct, pancreatic duct, and digestive tract, hollow organ in the body or stenosis. Esophagus is a hollow organ of organs for straight to the stomach, stent insertion is easy to insert among the digestive tract from the mouth. Esophageal stent has a structure that fine woven piece of shape memory alloys. Because that is folded thin, at the time of insertion can be safely inserted into the stricture that I get. Because of the shape memory alloy, we are in close contact with the wall of the esophagus lumen and to ensure a natural extension
Adaptation of esophageal stent treatment is the following cases. Stenosis cancer unresectable advanced esophageal cancer: advanced esophageal cancer esophageal cancer invasion to adjacent organs, organ metastasis, patients without chemotherapy or chemotherapy and radiation therapy can also be bad general condition. This is a difficult case of serious complications due to surgery also. Stenosis after chemoradiotherapy: main lesion stenosis was enhanced even reduced by chemotherapy or chemoradiotherapy, it is not indicated in patients with surgical resection.
May form a fistula and mediastinal trachea and bronchial esophageal cancer also increased         Esophageal stent insertion surgery is not a treatment for esophageal cancer itself. To be able to eat even a little spread narrowed esophagus for cancer it is the purpose of the maximum. For those who can not get enough to eat after stent insertion, perform endoscopic gastrostomy. We are also teaches home care management of nutrition in combination with diet and tube feeding. 
5.Therapeutic strategy for esophageal cancer
You can combine the above treatment, provide medical care advanced esophageal cancer based on the latest clinical guidelines in our hospital. Furthermore, even when treatment options is difficult, based on the extensive experience of our previous, in collaboration with departmental as General Hospital, we have made medical care the best possible state of esophageal cancer and comorbidity. Total power, including not only doctors, but also other co-medical staff such as nurses, laboratory technicians and rehabilitation is essential, in esophageal cancer clinics are a good practice to reflect the performance of our hospital.

Hardly a disease is associated with so many fears, such as cancer. Affected are confronted by their doctor with this diagnosis, the majority of them fall into a deep hole once. How will it go now? Thoughts of pain, suffering, long hospital stays, bed rest and death to come. Can help in this situation, especially information and knowledge about cancer.

What is cancer? 

3D VIEW OF CANCER CELL

Cancer - a disease of the genes
Cancer cells arise when changing certain parts of the genetic material (genes), these changes are not repaired and the genetic information "distorted" by it. The older a person is, the less reliable is working the repair system of genes. This is reflected in the incidence numbers: The median age for men and women for 69 years. However, there are cancers that affect young adults in particular. This includes for example testicular cancer: The median age here is 38 years.Mostly the women are effected by breast cancer and skin cancer.cancer is an challenge for medical science.it is a disease which can effect the total human body.The division of cell becomes abnormal in the case of cancer and because of abnormal division the generation of cancer tumors take place.  

Cancer-inducing factors

Factors that alter the genes and may promote cancer, including UV rays, tobacco smoke, chemicals, chronic infections, an increased consumption of alcohol and an unhealthy lifestyle with little fruit, vegetables and exercise. In five to ten percent of cases, the changes are genetic. In the families of cancer occurs in every generation and at a young age. More information about familial cancer can be found.Most of the rays coming from the sun is harmful to human skin and causes skin cancer the most efficient example of such rays is UV rays.there are many other factor like UV rays which causes cancer of diffrent types of cancer.Because of abnormal division of cell growth of tumors take place.

What makes cancer cells so dangerous?
Cancer cells stimulate themselves to divide and ignore growth inhibitory signals from the cellular environment. They can divide indefinitely and are potentially immortal. You are able to tap into existing blood vessels for their own survival. The dangerous properties of cancer cells, however, is in adjacent tissue to penetrate the body and to spread to distant sites to form metastases. In particular, these make a malignant tumor metastases to the life-threatening danger.

Cancer is a terrible and often fatal disease, there are a myriad of different types of cancer and almost every organ can be affected.
Even diseases of the heart and circulatory system are the leading cause of death is cancer but probably taking in the not too distant future this position, especially because cancer is a disease of the elderly and people in developed countries are living longer. Statistically, therefore, it is now so that every man who is not himself affected by cancer, at least one person closer knows or is related to her, has cancer. Cancer is therefore a huge medical problem and thus a major threat to public health and as big a challenge for science.

But few know what cancer is actually really. Cancer is the enemy in his own body, which degenerated from a sometime, therefore, mean 'become normal cell has emerged, which is step by step to a washed with all waters terrorist command, the armed against all the defenses of the body and often fatal has transformed.

If you understand how flexible and seemingly "brilliant" tumors, ie cancer tumors, organize themselves and their immediate cellular environment and modify it with nutrients and resources, and, totally disconnected from the real tasks of their cells of origin, and the need for "usefulness" for carry the organism, its own life and at the same time evolutionary arms race with the rest of the body, so that one can constantly remind ourselves that shall state that no evil, plan forming spirit behind it, which she imagines, then some not help but to feel that cancer is pretty scary.
But that's what makes cancer somehow mysterious and - as strange as it sounds - incredibly fascinating.The shape of a cells gets change in the case of cell and the division of cell is not in order.the cytoplasm of cancer cell is small.

Benign tumors copy their environment
Tumors can be benign in (Latin benign) and cancerous (Latin malignant) differ. Benign tumors usually just copy the tissue from which they originate. Accordingly, the individual cells are well developed and healthy cells, even confusingly similar. Benign tumors grow slowly as a rule, have clear boundaries and are limited to the affected organ. So they destroy the environment and do not cause long time with few or no symptoms.

Metastases -
In the jargon as "metastasis" is named - are not benign tumors They can usually be surgically removed easily and are rarely life-threatening. Through their growth, however, the adjacent organs or blood vessels and pressure tested in other organs in the area are damaged - especially if the growth of the space is lacking, as examined in the head. Then, a benign tumor can be so deadly. Examples of benign tumors are the fatty tumor, so the lipoma of the adipose tissue, and the nevus cell nevus of the skin - commonly referred by to as a "mole" or "birthmark".

3D view of Metastases

 Malignant tumors destroy organs
In malignant tumors, although usually recognizable from which they are derived tissue of origin, the individual cells are developed in very different ways. The worse they are developed and the less they resemble the cells of the tissue of origin, the more malignant the tumor. Malignant tumors can arise from previously benign tumors, which is also called "malignant".

Malignant tumors grow quickly, do not have clear borders, destroy neighboring organs and invade blood vessels and lymphatics. This allows tumor cells - almost like driftwood in a river - move to other organs and form metastases. Examples of malignant tumors of the colon, the lung, breast, cervix (cervical cancer), prostate cancer and malignant melanoma of the skin - also known as "skin cancer".

 Malignant tumors

 Cancer can have many causes
 Cancer is not a hereditary disease, but there are some cancers including breast, ovarian or colon cancer an inherited genetic predisposition. Thus, relatives of women with breast cancer, have a significantly increased risk, even to get breast cancer. This is due to differences in the genetic material of the women who are inherited. For most cancers, the genetic alterations develop but only in the course of life. They are not inherited but acquired.

Many cancer-causing factors are still unknown. The only certainty is that, among other environmental factors and lifestyle can contribute to the development. So is scientifically proven that chemical substances such as aromatic polycyclic hydrocarbons, which are in tobacco smoke and exhaust gases of combustion engines, can cause cancer. Other cancer-causing chemicals are aromatic amines such as aniline, which is needed to make dyes and drugs. Nitrosamines, which occur in many foods, such as cured meats, but also occur in the stomach from nitrates and nitrites can cause tumors in high doses. Also are carcinogenic fungal toxins, called mycotoxins. Most famous is the aflatoxin, which is found in the mold of different foods.

Diffrence between normal and cancer cell

The trigger for cancer is also radiation. Thus, a UV radiation (ultraviolet), the skin from the sun and tanning beds cause skin cancer. Radiation, including x-rays can damage the bone marrow. Because the bone marrow, the blood cells are formed, as a result of damage leukemias - that leukemia - arise. In addition, damage to thyroid and lymphatic tissue are possible. This can lead to thyroid cancer and lymphatic cancer called lymphoma come.

Moreover, viruses, such as human papillomaviruses cause tumors. Thus, in women, the human papillomavirus type 16 and 18 have in mucosal cells of the cervix, the risk of cervical cancer, the so-called cervical cancer, increased significantly. Other examples include certain adenoviruses and herpes viruses that can cause lymphatic and blood cancers. In addition, in patients with liver cancer often found the hepatitis B or hepatitis C virus, as liver cancer can arise as a consequence of liver inflammation.Finally, hormones trigger accelerate the growth of cancer, and, in particular, the sex hormones. Thus, the male sex hormone testosterone is associated with prostate cancer.Cancer is widespread

 The three most common cancers in men are: 
* Prostate cancer (more than 64,000 new cases per year),
* Colorectal cancer (about 39,000) and
* Lung cancer (35,000). 
The three most common cancers in women are:
* Of breast cancer (more than 59,000 new cases per year),
* Colorectal cancer (about 33,600) and
* Lung cancer (15,000).
Both women and men cancers lie behind diseases of the heart and circulation for many years, the number two cause of death statistics. In 2006 alone, according to the Federal Statistical Office, died nearly 112,800 men and nearly 98,000 women with cancer.

STATICS OF TYPE OF CANCER

Also in children and adolescents under 15 years are cancers - by accident - the second leading cause of death, although the prognosis in this age group are high at around 80 percent. The number of new cases is with them constantly for many years. The most common cancers are leukemia, tumors of the brain and spinal cord, as well as lymphoma.
