Cancer is a group of more than 100 diff erent diseases.
Benign tumors are not cancer; malignant tumors are cancer. Most cancers are named
for the type of cell or the organ in which they begin. When cancer spreads (metastasizes),
the new tumor has the same name as the original (primary) tumor. Skin cancer is
the most common type of cancer for both men and women. The second most common cancer
in men is prostate cancer, in women it is breast cancer. Lung cancer is the leading
cause of death from cancer for both men and women in the U.S. Cancer is NOT contagious.
