Genetic testing for cancer: Why it makes sense

Genetic testing has several important implications in the management of cancer

Genetic testing is generally done for patients with a significant family history of cancer, or some specific patterns of presentation of cancer. If a causative germline mutation is identified, the individual’s family members are also screened for it.

Thus, a cancer patient who gets suitable genetic testing done also helps save lives of family members by making them aware of any causative mutation present in their genes.
