Some people are more sensitive than others to factors that can cause cancer. Many cases of cancer can be prevented by not using tobacco products, avoiding the harmful rays of the sun, and choosing foods with less fat and more fiber. Although many risk factors can be avoided, others, such as inherited factors, are unavoidable. Still, it is helpful to be aware of them. People who have an increased likelihood of developing cancer can help protect themselves by avoiding risk factors whenever 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.
