Treatment for cancer

Complementary and alternative therapies

The phrases complementary therapy and alternative therapy are often used as if they mean the same thing. They are sometimes combined into one phrase – complementary and alternative therapies (CAMs). There is an important difference between a complementary therapy and an alternative therapy.

Complementary therapies are used alongside conventional medical treatments prescribed by your doctor. They can help people with cancer to feel better and may improve your quality of life. They may also help you to cope better with symptoms caused by the cancer. Or side effects caused by cancer treatment.

Alternative therapies are used instead of conventional medical treatment. People with cancer have various reasons for wanting to try alternative therapies.
