Overview

Complementary and alternative medicine (CAM) includes a wide variety of therapies, botanicals, nutritional products, and practices. These forms of treatment are used in addition to (complementary) or instead of (alternative) standard treatments. The 2007 National Health Interview Survey reported that about 4 out of 10 adults use a CAM therapy, naming natural products and deep breathing exercises as the most commonly used treatments.

One large survey reported on the use of complementary therapies in cancer survivors. The therapies used most often were prayer and spiritual practice, relaxation, faith and spiritual healing, and nutritional supplements and vitamins. CAM therapies are used often by children with cancer, both in and outside clinical trials. CAM therapies have been used to manage side effects caused by cancer or cancer treatment.
