Breast Cancer


Cannabis for Breast Cancer

About 1 in 8 U.S. women (about 13%) will develop invasive breast cancer over the course of her lifetime. Except for skin cancers, breast cancer is the most common type of cancer amongst women in the US. About 281,550 new cases of invasive breast cancer will be diagnosed in women, of which an estimated 43,600 women will die. Breast cancer is the second leading cause of cancer death in women, after lung cancer.

Although conventional treatments can work very well for many types of breast cancer, some types are very aggressive and do not respond as well to chemotherapy or radiation therapy. Alternatives are needed, and cannabinoids could represent one of them. Both THC and CBD may be useful for treating the side-effects of chemotherapy and cancer pain as well. Lower amounts of THC may be needed for estrogen-positive breast cancer., but we do not have any clinical evidence to suggest dosing guidelines regarding specific cannabinoids, so information at the moment is speculative and based on theory derived from the current body of literature on the subject.
