Hormone-sensitive breast cancer, also known as hormone receptor-positive breast cancer, occurs when cancer cells grow in response to hormones like estrogen and progesterone. These hormones can bind to receptors on the cancer cells, promoting their growth and division. This type of breast cancer is often detected through imaging and biopsy, and it can be classified based on the presence of these hormone receptors. Treatment for hormone-sensitive breast cancer typically involves therapies that block hormone production or action, such as tamoxifen or aromatase inhibitors. These treatments aim to reduce hormone levels in the body or prevent hormones from binding to cancer cells, thereby slowing or stopping tumor growth. Regular monitoring and follow-up care are essential for managing this condition.
