What do hormone blockers do to get rid of breast cancer?
The most common hormone therapy drug is Tamoxifen. It blocks the estrogen-shaped openings in the cells, preventing estrogen-fueled cancers from growing.
Tamoxifen can be taken as a pill on a daily basis, up to five years after surgery.
What are hormone inhibitors and how do they work?
Hormone inhibitors also target breast cancer cells with hormone receptors, but unlike hormone blockers, they work by reducing the body’s hormone production. When breast cancer cells are cut off from the ‘food supply’ (in this case, estrogen) the tumor begins to starve and die.
Generally, the benefits of using hormone therapy and chemotherapy together have a much greater combined effect than using either alone. If your breast cancer is positive for hormone receptors, your doctor may recommend both therapies.
