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?
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".
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".
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.
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.
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.
