Definition - Cancer is a group of more than 100 diseases. Although each type of cancer differs from the others in many ways, every cancer is a disease of some of the body's cells.


Healthy cells that make up the body's tissues grow, divide, and replace themselves in an orderly way. This process keeps the body in good repair. Sometimes, however, normal cells lose their ability to limit and direct their growth. They divide too often and grow without any order. Too much tissue is produced, and tumors begin to form.

Tumors can be benign or malignant. Benign tumors are not cancer. They do not spread to other parts of the body and are seldom a threat to life. Often, benign tumors can be removed by surgery, and they are not likely to return.

Malignant tumors are cancer. They can invade and destroy nearby healthy tissues and organs. Cancer cells (such as the cells that make up the skin cancers shown here) also can spread, or metastasize, to other parts of the body and form new tumors. Definition from National Institutes of Health.
