What is cancer?

Cancer is a large group of diseases with one thing in common: They all happen when normal cells become cancerous cells that multiply and spread.

Cancer is the second most common cause of death in the U.S. But fewer people are dying of cancer now than 20 years ago. Early detection and innovative treatments are curing cancer and helping people with cancer live longer. At the same time, medical researchers are identifying independent risk factors linked to developing cancer to help prevent people from developing cancer.
