Oncologists need to ask about herbs and supplements

A large percentage of cancer patients use complementary and alternative medicine, including herbs and supplements, while undergoing treatment. However, fewer than half of US oncologists ever initiate discussions about the use of these products, according to the results of a new survey. Some research on antioxidant vitamins has shown that when head/neck cancer patients used them during radiotherapy, there was a trend toward increased cancer recurrence and second primary cancers.
