Hormone receptor-positive (HR+)

Hormone receptor-positive (HR+) refers to cancers, often breast cancers, that have cells with molecules called hormone receptors—specifically for hormones like estrogen or progesterone. These receptors allow the cancer cells to respond to hormones that can promote their growth. Identifying HR+ status helps doctors choose targeted treatments, such as hormonal therapy, which blocks the hormones' effects and can slow or stop the cancer's progression. Essentially, HR+ cancers are influenced by the body's natural hormones, and understanding this helps tailor more effective treatment strategies.
