Estrogen receptor-positive (ER-positive) breast cancer means the cancer cells have receptors that attach to estrogen, which helps them grow. It's one of the most common types of breast cancer.
The good news is that ER-positive breast cancer tends to respond well to hormone therapies, which work by either blocking estrogen receptors or reducing the amount of estrogen your body produces. Here are some key things to know about ER-positive breast cancer:
- Hormone therapy (like tamoxifen) is a common treatment that blocks estrogen from fueling cancer cell growth
- Recurrence risk is generally lower in the first five years compared to ER-negative cancer, but the risk can increase after 10 or more years
- Targeted drugs like ribociclib (Kisqali) may help reduce the chances of recurrence
- Diet considerations matter — certain foods like grapefruit and tangerines can interfere with tamoxifen's effectiveness, so it's worth discussing your diet with your oncologist Always work closely with your oncologist to find the treatment plan that's right for you. Everyone's situation is a little different, and your care team can help tailor the best approach based on your specific diagnosis.
