theories Cancer triggers

According to the above theory are mainly influences that alter the genetic material, cause cancer. Particularly sensitive for the cell during cell division, so are cells that divide quickly, particularly vulnerable. Even influences that prevent the immune system from recognizing and eliminating malignant cells are considered carcinogenic. Especially dangerous are therefore: * Physical

pollutants
o ionizing radiation such as ultraviolet light, X-ray or gamma radiation. Example: When Koronaruntersuchung by computer purchase is the increased sensitivity of patients with an increased risk of cancer. American scientists thus calculated that sick at twenty year olds of 143 examined by coronary CT women in their lives due to this radiation angiography with cancer, but only one of 686 men the same age. The CT angiography of the coronary arteries seems especially among women and young people to increase the cancer risk is not negligible [3].
* Chemical pollutants
o mutagenic chemicals. The most important are large polycyclic aromatic hydrocarbons, Benzene, chromium (VI) compounds and nitrosamines.
* oncoviruses (as estimated by the American Cancer Society, about 17% of cancer cases [4])
o Several DNA viruses (eg hepatitis B virus (HBV), which hepatocellular carcinoma, and HPV, which can lead to cervical cancer)
o Several RNA viruses
* Some tumors can be transmitted from animal to animal, including the Sticker sarcoma of dogs and DFTD (Devil Facial Tumour Disease) of the Tasmanian devil. [5]
* stem cells can trigger in certain circumstances cancer. [ 6]
* The Million Women Study confirmed the assumption that obesity increases the risk of cancer. An elevated body mass index had both the incidence and mortality increase as the following cancers: endometrial cancer, esophageal cancer, kidney cancer, multiple myeloma, pancreatic cancer, non-Hodgkin's lymphoma, ovarian cancer, breast cancer and colon cancer after menopause. This can be according to the study authors 5% of all cancer cases in overweight and obesity lead back.
