Cancer, a condition resulting from abnormal cell division presents more than 100 types of cancer named after the organ or cell type from which they originate. Irregular splitting up of cells that afterward attacks various body tissues normally causes Cancer diseases. Cancer stretches to various body parts with time making the cancerous cells malignant. If not treated immediately after diagnosis, it can cause complicated illnesses that can cause death. The leading cause of deaths is cancer with almost two-thirds of it being caused by ecological factors. There are various environmental causes of cancer with the term environment referring to the external environment as well as the personal environment.
When determining what factors in the environmental cause cancer, various factors can be attributed to it. The causes of cancer can either be tied to the external or personal environment. The personal environment factors likely to cause the cancer include lifestyle preferences like tobacco and diet. Tobacco has been said to be the cause of about one third of deaths caused by cancer yearly. Ultra violet rays arising from sunlamps, the sun itself or tanning beds are known to cause various kinds of skin cancer like melanoma. The environmental causes of cancer arise from lifestyle factors and exposure to water or air agents. Some of the different environmental agents likely to cause cancer include occupational exposures, ionizing radiation, chemicals, medical drugs and even alcohol.
Over past years, it has been estimated by epidemiologists that there are many death percentages attributed to environmental factors. For example, thirty percent of cancer deaths have been credited to tobacco. Medical procedures, nutrition and diet, alcohol, gynecologic or reproductive factors, chemical substances, asbestos exposure, magnetic field and electric exposure and exposure to nuclear facility are other cancer causes. When finding out what causes cancer, keep in mind that various environmental factors, both external and personal cause cancer. Research has proven Ultraviolet and ionizing radiation to be cancer causes to humans. The sun produces ultraviolet radiation and excess exposure to the UV radiation is the main cause of melanoma, squamous cell and basal skin cancers.
Carcinogens are materials that increase the chances or risk of cancer. When determining what environmental factors cause cancer, consider environmental carcinogens. These carcinogens may make direct or indirect damages to the DNA and may cause cancer. This is a probable explanation as to why not every environmental exposure to carcinogens may cause cancer. The time span of the exposure and its intensity is also a determining factor of whether one will develop cancer. A number of known environmental carcinogens include chemical surfactants, water or air pollution, and various infectious agents like parasites, bacteria and viruses.
Generally, the main environmental causes of cancer are related to the personal environment of an individual and include lifestyle choices such as tobacco use and diet among others. External environmental factors referring to agents in the environment like environmental pollutants, sun exposure and radiation also increase cancer risks.
