Different Hormonal Therapies Cause Different Side Effects

When deciding on the best treatment plan for YOU, you and your doctor will consider the benefits of each treatment, as well as the possible side effects of each option.

A study showed that two hormonal therapy medicines used to reduce the risk of breast cancer coming back (recurrence) have different side effects. Women who received tamoxifen were more likely to have hot flashes and vaginal bleeding than women who got Aromasin (chemical name: exemestane). Women who got Aromasin were more likely to have bone and muscle aches, vaginal dryness, difficulty sleeping, and decreased interest in sex. These differences are probably because the two medicines work in different ways.

If you're taking adjuvant hormonal therapy medicine to reduce your risk of breast cancer coming back, you might have some of the side effects mentioned here. If the side effects are a problem, talk to your doctor about managing them or switching medications. Don't let side effects stop you from doing all you can to lower your risk of recurrence.
