A study published in the Journal of Clinical Oncology, July 18, 2000 shows that Ontario women diagnosed with breast cancer in 1994 or 1995 elected to use some form of what the study termed, "Complementary/Alternative Medicine" including chiropractic. The study conducted at the Centre for Studies in Family Medicine, Faculty of Medicine and Dentistry, University of Western Ontario, randomly surveyed women from Ontario diagnosed with breast cancer.
Overall, 66.7% of the respondents reported using some form of Alternative Medicine most often in an attempt to boost the immune system. The most common form of what the study classified as alternative medicine was chiropractic. In addition, 62.0% reported use of home alternative products, most frequently vitamins/minerals, herbal medicines, green tea, special foods, and essiac. Interestingly though was that slightly less than half of the patients using these procedures informed their medical doctors.
