But you can take the
uncertainty out of treating it.

What is HR+ Breast Cancer?

HR+ breast cancer grows in response to estrogen and/or progesterone, hormones naturally produced in the body. It may also be referred to as estrogen receptor–positive (ER+) or progesterone receptor–positive (PR+).

According to the American Cancer Society, about two out of three breast cancers are HR+.

How Is Anti-Estrogen Therapy Used To Treat HR+ Breast Cancer?

Most women with HR+ breast cancer are prescribed anti-estrogen therapy as part of their treatment, which may suppress estrogen and/or progesterone to help slow or stop additional cancer growth.

While the duration of treatment may vary from patient to patient, at least 5 years of anti-estrogen therapy is typically prescribed with the goal of preventing the cancer from recurring.

Together, she and her oncology team must decide whether the potential benefit of extending her treatment outweighs the potential side effects and risks associated with the medication.

Whether or not she is likely to benefit, Breast Cancer Index^® gives her and her oncology team information they need to make a more informed treatment decision.
