Cancer
Cancer i/ˈkænsər/, known medically as a malignant neoplasm, is a broad group of various diseases, all involving unregulated cell growth. In cancer, cells divide and grow uncontrollably, forming malignant tumors, and invade nearby parts of the body. The cancer may also spread to more distant parts of the body through the lymphatic system or bloodstream. Not all tumors are cancerous. Benign tumors do not grow uncontrollably, do not invade neighboring tissues, and do not spread throughout the body. There are over 200 different known cancers that afflict humans.

—Ishmael Reed (b. 1938)
“The same people who tell us that smoking doesn’t cause cancer are now telling us that advertising cigarettes doesn’t cause smoking.”

—Gilbert Adair, British author, critic. “Under the Sign of Cancer,” Myths and Memories (1986)
