What type of breast cancer is caused by estrogen? If a person has hormone receptor-positive breast cancer, it means that their breast cancer cells have estrogen receptors (ERs), progesterone receptors (PRs), or both. Hormone receptor-positive breast cancer can respond well to different treatments.
How much does estrogen increase risk of breast cancer?
