In 2008, Nancy White Gamble learned that she had a rare form of leukemia called acute promyelocytic leukemia. APL, a type of acute myeloid leukemia, used to be a difficult cancer to manage. Fortunately, today it is not only treatable, but curable. After two years of treatment, Gamble, now 59, got a clean bill of health and resumed her active charity work in the Napa Valley, where she lives.
