Metatstatic Breast Cancer Treatment
Metastatic breast cancer (MBC) can be categorized into different subtypes based on the characteristics of the cancer cells. Each subtype may require a different approach to treatment, so your healthcare team will tailor your care plan based on the specific type of cancer you have. Understanding your cancer’s subtype can help you and your doctors work together to choose the most effective treatment options.
Hormone Receptor-Positive (HR+,HER2-)
The cancer cells have receptors for hormones like estrogen (ER) and/or progesterone (PR). These hormones can help the cancer grow.
Treatment Options: Treatment options aim to slow down or stop the cancer’s growth. These often include hormone therapies that either block the hormones or reduce their levels in the body. Additional options may include CDK 4/6 inhibitors, mTOR inhibitors, chemotherapy, or therapies targeting inherited genetic mutations or specific mutations within the tumor.
