Risk Factors for Cancer495 Views
Understanding Cancer will start in
Over a million people are diagnosed with cancer every year. Understand cancer better and you may minimize your risk and cope with it better if you or a loved one is diagnosed with it.
Description: You can't always avoid cancer, but sometimes you can lower your risk factors for cancer. Learn about what you can, and can't, control, in this video.

Anyone can develop cancer, and many people do. Some form of this disease is likely to affect one-third of American women and one-half of American men in their lifetimes. Cancer stems from genetic mutations in the body’s DNA. The result is the rapid growth of unhealthy cancerous cells in the body. If left undiagnosed, or if treatment fails, these cells can migrate, or spread, to vital organs. The result can be severe illness or even death. Cancer-causing DNA mutations occur for a variety of reasons, some of them uncontrollable.
For example, more than 75 percent of new cases are diagnosed in people who are 55 years of age and older.
Heredity plays a role in 10 percent of cancers, whereby a mutation is passed from one generation to the next. Prostate cancer in men, and breast cancer in women, are especially likely to be hereditary. Perhaps 15 percent of cancers stem from viral infection. Notably, the human papillomavirus, or HPV, is a sexually transmitted virus that can result in genital warts or cervical cancer. Another STD, hepatitis B, can lead to the development of liver cancer. In addition, HIV, the virus that causes AIDS, can lead to several potentially deadly cancers such as Kaposi’s sarcoma or non-Hodgkin’s lymphoma. However, having protected sex, and engaging in intercourse with a limited number of partners can help reduce the risk of contracting cancer-causing viruses. Even better, some cancer risk factors ARE controllable, like the use of tobacco products. Last year, more than one-third of cancer-related deaths were from lung cancer. Another third of cancer-related deaths, such as those from thyroid and colon, may have been preventable by engaging in certain healthy lifestyle choices, like regular exercise and excellent nutrition. In addition, the one million cases of skin cancer which are diagnosed each year are often related to overexposure to the sun’s rays. Even one’s environment can lead to cancer. Children and spouses of smokers, for example, are much more likely to develop lung cancer. Chemicals like asbestos can still be found in some workplaces and homes and can lead to cancer of the lung, kidneys, and larynx. While these factors are very real, a number of myths regarding cancer abound. These so-called risk factors actually have no bearing on the development of cancer. For example, there’s no conclusive evidence that using underarm deodorant causes breast cancer, or that microwaving plastic containers or wraps releases cancer-causing toxins. Even more importantly, cancer is NOT contagious, which means you can not catch it from spending time with someone else. That’s good news, because with the millions of new cancer cases diagnosed each year, you probably know someone with the disease. Although many cancers are not preventable, some, such as cervical, breast and prostate can be slowed or even eradicated with early detection. For this reason, people with multiple risk factors should talk to their doctors about regular screening.
