Cancer is described as a group of diseases that are typical for the growth of abnormal cells. Cancer is not so much illness is a disease cell of the body of any living organisms.
In our bodies we have control of the regulatory mechanism, which allows you to his birth, life, death and reproduction ability. The rate at which this is carefully controlled. If something happens with this control mechanism, cell division becomes much more quickly then develop tumors. When these tumors are malignant, atypical of their cancer cells may fall into the blood and lymphatic system, and transferred to various parts of the body. This spread of cancer cells is called metastasis. What happens to the control mechanism, which allows this wild growth of cells is a researcher to appear. Only the cancer cells do not produce faster but differ in their nature ". Their structural differences are such that they can in many cases, met under the microscope. Even Though; the specific causes of cancer is unknown, only a number of related contributing factors and possible causes have been identified. Overexposure to radiation was found to be predurcujících factor for the formation of cancer.
Animal cancer have been identified as produced by viruses. There is a suspicion that these micro-organisms also play a role in the development of some human cancers. To date, however, no specific virus has been identified as cancer production in humans. The recent merger of the type of herpes virus with Lymphoma (cancer of the lymph glands), which occur mainly in African children and Baylor University researchers mention virus herpes type II present in 83 percent of patients with cancer of the cervix provides new tools for the investigation along this line.
