Abstract
Lesbian and bisexual cisgender women have higher rates of breast cancer and breast cancer mortality than their heterosexual counterparts (Committee on Lesbian, Gay, Bisexual, and Transgender Health Issues and Research Gaps and Opportunities, 2014). There is not much known about why this is the case, although most researchers revert to the common hypotheses that the increased prevalence of obesity, substance abuse, and nulliparity (not having given birth) among lesbian and bisexual women contributes to incidences of breast cancer (Committee on Lesbian, Gay, Bisexual, and Transgender Health Issues and Research Gaps and Opportunities, 2014). These hypotheses place individual responsibility on sexual minority women with breast cancer as opposed to identifying complicated, underlying structural problems. This literature review argues that homophobia and bisexual invisibility, in conjunction with fatphobia and inaccurate research methodology, have prevented clinicians and scientists from thoroughly examining the ways in which increased rates alcohol abuse, the physiological effects of stress due to discrimination, and a lower rate of receiving mammograms caused by perceived negative judgment from healthcare providers contribute to the higher prevalence of breast cancer among lesbian and bisexual women.
