A cure for cancer remains a mystery. But research is focusing on preventing this disease through changes in lifestyle. Studies show that a number of behaviors may affect a person's chance of getting cancer. In fact, as many as half of all cancer deaths could be avoided through changes in diet, smoking, and exercise, and through early detection. Giving up cigarettes is one of the most important ways of reducing cancer risk.
Cigarette smoking is responsible for most cases of lung cancers in women.
There are many other things you can do to reduce your risk of cancer. A diet that includes plenty of vegetables and fruits may reduce a person's risk of some cancers, such as lung and stomach. They are a good substitute for fatty foods. Studies are looking into whether beta carotene can help prevent several cancers, such as cervical. The body turns beta carotene into vitamin A. Calcium may play a role in preventing colon cancer.
