"People who are survivors might want to know, 'Why did this cancer happen to me?' They may also want to know if they have risk for developing another cancer." — Judy Garber, MD, MPH
About 5 percent of all cancers are inherited. In these cases a person inherits a gene in which the risk of getting cancer is 50 percent or more.
Genetic tests can check whether families with a history of certain types of cancers carry a mutation that predisposes them to the disease. Such tests may help survivors and their family members take special steps to detect cancer early or prevent it altogether.
