Doctors tend to urge cancer patients to discuss supplements with their doctors before beginning treatment because they may negatively affect chemotherapy. Some herbs interfere with the metabolism of chemotherapy drugs. Another problem is that MDs are not trained in nutrition, herbs and supplements and generally discourage the use of any treatment they are unfamiliar. They should be asking the same questions of most pharmaceutical drugs as well, but tend to trust them blindly. It is possible to treat with supplements away from chemotherapy or radiation treatments. Some herbs could support chemotherapy and others are interesting complementary styles of chemotherapy too.
