For this reason, the National Cancer Institute is studying many screening tests to find out how useful they are. Many cases of cancer can be prevented by not using tobacco products, avoiding harmful rays of the sun, and choosing foods with less fat and more fiber. Many risk factors can be avoided. Others, such as inherited factors, are unavoidable. People who have an increased likelihood of getting cancer can help protect themselves by avoiding risk factors where possible and by getting regular checkups so that, if cancer develops, it is likely to be found early.
Treatment is likely to be more effective when cancer is detected early.
