Some breast cancers need the hormones estrogen or progesterone to grow. These cancer cells have "receptors" on their surfaces. Receptors are like doorways to let hormones in.
These types of breast cancer are called estrogen-receptor-positive (ER+) or progesterone-receptor-positive (PR+) breast cancer.
Hormone treatment keeps these cancers from getting the hormones they need. It's like starving the cells so that they stop growing. Sometimes they even shrink.

Managing side effects
Some hormone treatments cause menopause symptoms like vaginal dryness, mood swings, and hot flashes. If you have mild symptoms, you may get some relief if you eat healthy foods, exercise, and lower your stress.
Talk to your doctor if you have severe symptoms that aren't helped by making changes to your lifestyle. You may be able to take medicine to help your symptoms.
Some hormone treatments cause thinning bones. Talk to your doctor to make sure you are doing all you can to protect your bones.
