Definition of CancerDefinition of Cancer
What is cancer?What is cancer? The body is made up of trillions of living cells. Normal body
cells grow, divide, and die in an orderly way. During the early years of a person's life, normal cells divide faster to allow the person to grow. After the person becomes an adult, most cells divide only to replace worn-out, damaged, or dying cells.
Cancer begins when cells in a part of the body start to grow out of control. There are many kinds of cancer, but they all start because of this out-of-control growth of abnormal cells.

For this reason, major neither test helped patients live longer. For this reason, major medical organizations have not recommended routine medical organizations have not recommended routine screening with these tests for the general public or even for screening with these tests for the general public or even for people at increased risk, such as smokers.
