Are placebos ever used in breast cancer treatment trials?
Placebos are never used when a cancer patient would be put at risk by not having effective therapy for their cancer. Patients who join cancer clinical trials that are testing a new cancer treatment are given either the standard of care (the best treatment available for their specific cancer), or receive a new treatment being investigated. Only in the rare instance that there is no treatment proven to be effective against a certain type of cancer would patients be randomized to a placebo.
