Cancer identifies a disease that arises due to the cells abnormally dividing then later attacking other body tissues. The cancerous cells usually extend to other parts of the body via the lymphatic or blood system. The environmental causes of cancer refer to those factors that do not relate to inherited or hereditary factors. Cancer has been termed to be one of the major death causes with over two-thirds of it arising from environmental factors. With the knowledge that various environment agents can cause cancer, it is vital for people to change their lifestyles and environmental activities that are likely to cause cancer.
There are many factors that can be considered when determining what environmental factors cause cancer. Tobacco normally accounts for almost one-third of cancer deaths every year. Ultra violet radiation brought about by the sun, tanning beds or sunlamps cause melanoma and other skin cancer forms. Environmental causes of cancer comprise both lifestyle factors like diet and smoking and exposure to particles or agents in water and air. There are many categories of those agents found in the environment that are known to cause cancer. Some of them include infectious agents, tobacco, diet, alcohol, occupational exposures, ionizing radiation and medical drugs.
Over years, epidemiologists have estimated the new cancer cases and death percentages caused by environmental agents. For instance, about 30% cancer deaths are attributed to tobacco. Other cancer cases are caused by water and air pollution, occupations, medical procedures and medicine. When establishing what environmental factors cause cancer, it is important to bear in mind some of these environmental factors. Another environmental cause of cancer is ionizing radiation. Exposure to radiation from sources like radon, cosmic rays, atomic bombs, nuclear bomb tests done on the ground and X-ray is a cause of cancer.

Carcinogens identify substances believed to increase the risk of developing cancer. To make out what environmental factors cause cancer, bear in mind environmental carcinogens. In some instances, carcinogens damage the DNA directly while in some, the cause is indirect. This explains why not each exposure to a carcinogen leads to cancer. The extent and intensity of exposure to ecological carcinogens determines the chances of developing cancer. Some ecological carcinogens include chemicals, infectious agents, and air pollution. Exposure to particular chemicals, parasites, and bacteria are known risk factors for various cancer types.
The main environmental causes of cancer are generally associated with the personal and external environment. Radiation, sun exposure and environmental pollutants are some of the external environmental cancer causes. Individuals ways of life ranging from the diet to the elements one uses or is exposed to like tobacco and nutrition have been proven to cause cancer.
