Safety is a concern for complementary therapies. Unlike standard medical treatments, many complementary therapies are not regulated by the federal government and may not have quality controls.

Although the idea of "natural" products is appealing, "natural" does not mean "safe" (think about poison ivy and poisonous mushrooms). The Food and Drug Administration (FDA) has limited oversight on dietary supplements and does not regulate them as strictly as medications.

If you suspect a product or therapy is making a false claim that it prevents or cures cancer, check the Federal Trade Commission (FTC)'s Cancer Treatment Scams website for any consumer warnings. Your health care provider is also a good source for this information.
