An actor who got cancer

Cancer refers to any one of a large number of diseases characterized by the development of abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal body tissue. Cancer often has the ability to spread throughout your body. Cancer is the second-leading cause of death in the world. But survival rates are improving for many types of cancer, thanks to improvements in cancer screening, treatment and prevention. Signs and symptoms caused by cancer will vary depending on what part of the body is affected. Cancer is caused by changes (mutations) to the DNA within cells.
