Complementary therapies are treatments that people may use with, or as well as, conventional medical treatments. Complementary therapies should not claim that they can treat or cure cancer.

Alternative therapies are treatments that people use instead of conventional medical treatments. Some alternative therapies claim to treat, or even cure, cancer.

Most alternative therapies are not scientifically tested and researched like conventional medical treatments. Some have been tested. But no alternative therapy has been proven to cure cancer or slow its growth. Some may even be harmful.

If you are worried about conventional treatment it’s best to talk to your cancer team about your worries. They can talk you through what to expect and how they they can support you through it.
