A Cancer in the Family

Oncologist and cancer gene hunter Theo Ross delivers the first authoritative, go-to for people facing a genetic predisposition for cancer.

There are 13 million people with cancer in the United States, and it's estimated that about 1.3 million of these cases are hereditary. Yet despite advanced training in cancer genetics and years of practicing medicine, Dr. Theo Ross was never certain whether the history of cancers in her family was simple bad luck or a sign that they were carriers of a cancer-causing genetic mutation. Then she was diagnosed with melanoma, and for someone with a dark complexion, melanoma made no sense. It turned out there was a genetic factor at work.
