Complementary and alternative medicine (CAM) is the term for medical products and practices that are not part of standard medical care.
Standard medical care
Standard medical care is medicine that is practiced by health professionals who hold an M.D. (medical doctor) or D.O. (doctor of osteopathy) degree. It is also practiced by other health professionals, such as physical therapists, physician assistants, psychologists, and registered nurses. Standard medicine may also be called biomedicine or allopathic, Western, mainstream, orthodox, or regular medicine. Some standard medical care practitioners are also practitioners of CAM.
Complementary medicine
Complementary medicine is treatments that are used along with standard medical treatments but are not considered to be standard treatments. One example is using acupuncture to help lessen some side effects of cancer treatment.
Alternative medicine
Alternative medicine is treatments that are used instead of standard medical treatments. One example is using a special diet to treat cancer instead of anticancer drugs that are prescribed by an oncologist.
Integrative medicine
Integrative medicine is a total approach to medical care that combines standard medicine with the CAM practices that have shown to be safe and effective. They treat the patient's mind, body, and spirit.
Are CAM approaches safe?
Some CAM therapies have undergone careful evaluation and have found to be safe and effective. However there are others that have been found to be ineffective or possibly harmful. Less is known about many CAM therapies, and research has been slower for a number of reasons. More read about this National Cancer Institute as the source.
