Labriola works with cancer patients who wish to pursue both conventional treatment, such as chemotherapy and surgery, and alternative medical approaches, such as dietary, botanical and psychological therapies. His book, Complementary Cancer Therapies, has received praise from both the mainstream and alternative cancer communities for its balanced approach, making Labriola one of the few physicians in the United States to successfully bridge the two. He works as a consultant to hospitals, bone marrow transplantation centers, and cancer treatment facilities worldwide.
