What is Cancer?: Cancer is the uncontrolled growth of a part of the body, with the potential for spread locally or to distant locations, causing dysfunction or organ failure and, ultimately, death.

Cancers tend to deprive a patient of nutrients, damaging the immune system, increasing infection risk.
