Survey data about how many cancer patients use<unk>  or complementary therapies vary from nation to nation as well as from region to region. A 2000 study published by the European Journal of Cancer evaluated a sample of 1023 women from a British cancer registry suffering from breast cancer and found that 22.4% had consulted with a practitioner of complementary therapies in the previous twelve months. The study concluded that the patients had spent many thousands of pounds on such measures and that use "of practitioners of complementary therapies following diagnosis is a significant and possibly growing phenomenon". In Australia, one study reported that 46% of children suffering from cancer have been treated with at least one non-traditional therapy. Further 40% of those of any age receiving palliative care had tried at least one such therapy. Some of the most popular<unk>  were found to be dietary therapies, antioxidants, high dose vitamins, and herbal therapies. Use of unconventional cancer<unk>  in the United States has been influenced by the U.S. federal government's National Center for Complementary and<unk>  Medicine (NCCAM), initially known as the Office of<unk>  Medicine (OAM), which was established in 1992 as a National Institutes of Health (NIH) adjunct by the U.S. Congress. More specifically, the NIC's Office of Cancer Complementary and<unk>  Medicine sponsors over $105 million a year in grants for pseudoscientific cancer research. Over thirty American medical schools have offered general courses in<unk>  medicine, including the Georgetown, Columbia, and Harvard university systems, among others.
