Physicians' and Women's Views on Hormone Therapy and Breast Cancer Risk After the WHI: A Qualitative Study

Abstract

Background: The use of menopausal hormone therapy (HT) has significantly declined since the release of the Women's Health Initiative findings, but to what extent physicians' and women's concerns about breast cancer contributed to this change is unknown. Our study explored physicians' and women's beliefs about hormone therapy and breast cancer risk.

Methods: We conducted qualitative in-depth interviews with 22 primary care physicians and 45 female patients at two large integrated health care delivery systems in Washington State and Massachusetts.

Results: Concerns about breast cancer risk weighed into the decision-making process for physicians and women in initiating and continuing hormone therapy. For women, control of menopausal symptoms was important and possibly outweighed their concerns about the potential risks of breast cancer. Though concerned about its association with increasing breast cancer risk, physicians were willing to consider hormone therapy to manage women's menopausal symptoms but were frustrated about the lack of available non-hormone therapy alternatives. Most physicians and some women were aware of the Women's Health Initiative, and its findings appeared to influence their beliefs about hormone therapy and breast cancer risk, though doubts remained among both groups about the study findings and implications.

Conclusions: Our qualitative study suggests that after the Women's Health Initiative, concerns about breast cancer risk weighed into decisions to initiate and continue hormone therapy for both physicians and women, but menopausal symptoms often directed use.
