In this episode of unPAUSED, Dr. Mary Claire Haver sits down with Dr. Eleonora Teplinsky, a board certified medical oncologist specializing in breast and gynecologic cancers and author of Beyond the Pink. Together they challenge one of the most persistent beliefs in menopause care, that a history of breast cancer means you can never take estrogen or hormone replacement therapy. As Breast Cancer Awareness Month wraps up, Dr. Teplinsky makes the case that awareness is only the beginning, and that what comes after diagnosis deserves just as much attention.

Breast cancer treatment often pushes women into early menopause, yet most breast cancer survivors never get a conversation about hot flashes, night sweats, vaginal dryness, sexual health, or their options. Dr. Teplinsky explains why menopause and HRT after breast cancer were barely part of her oncology training. She also explains why estrogen does not cause breast cancer, though it can fuel the growth of hormone receptor positive cancer cells that already exist.

The conversation then turns to how breast cancer recurrence risk is assessed for an individual survivor. They cover who should hold off on systemic hormone therapy, who may be a reasonable candidate, and what the older trials on hormone therapy after breast cancer can and cannot tell us today. They also point out that for some survivors, drinking alcohol may raise recurrence risk more than hormone therapy would, yet few women are ever warned about it. Rather than a flat refusal, they argue that each woman deserves to weigh her own risks and benefits with her doctor and make the choice herself.

A big part of the episode centers on genitourinary syndrome of menopause, which affects most survivors. It hits especially hard for women on aromatase inhibitors, a treatment Dr. Teplinsky describes as menopause on steroids. They discuss recurrent UTIs and pain with sex. They explain why guidelines support low dose vaginal estrogen even for women taking tamoxifen or aromatase inhibitors, and how to apply it for the most benefit. They also cover vaginal DHEA and a recent oncology guideline change that moved testosterone from contraindicated to use with caution.

The episode closes with a three step script for your next appointment: name your symptoms without downplaying them, ask what hormone therapy would mean for your specific recurrence risk, and ask for a referral if your clinician can’t answer.
