Hormone therapy is proven to be an effective treatment for breast cancers that are found to have receptors for the naturally occurring hormones estrogen or progesterone. Aromatase inhibitor therapy is one of the most effective ways to treat ER-positive breast cancer in people who have gone through menopause. Studies show 95% of people who receive aromatase inhibitor therapy after breast cancer surgery don't have breast cancer signs five years after completing treatment.

Aromatase inhibitor therapy has side effects that may affect your quality of life. For some people, these side effects can be managed. The choice to discontinue treatment is a personal choice. If you’re taking an aromatase inhibitor, you may wish to talk to your oncologist or symptom management nurse about ways to reduce side effects so you can continue treatment that helps you live free of breast cancer.

Strength and weight bearing exercises and a positive attitude are not a substitute for hormonal therapy. That said a healthy lifestyle that includes eating well and physical activity as well as taking care of your emotional health contribute positively to one's overall health and wellbeing.
