Is vaginal estrogen safe after breast cancer?

Answer published
Low-dose vaginal estrogen — cream, ring, or tablet — produces minimal systemic absorption (serum levels stay in the postmenopausal range with consistent use). ACOG, NAMS, and the American Society of Clinical Oncology have all moved toward considering it acceptable for many breast cancer survivors with severe genitourinary syndrome of menopause (GSM), particularly when non-hormonal options have failed. The decision is individualized and should involve your oncology team, especially if you are on an aromatase inhibitor. The non-hormonal first-line is high-quality moisturizers and lubricants.

Estrogen-alone HRT does not raise breast cancer risk in WHI data. Combined HRT shows a small absolute increase after ~5 years. Risk is lower than alcohol or obesity.
