Lesbian and Bisexual Women’s Health: Breast Cancer and Gynecological Risk Factors
December 2014 | Felixia Barias
Information on breast cancer rates amongst lesbians and bisexual women have been inadequate and inconsistent. Only a handful of studies have specifically addressed lesbian cancer risks and experiences and their findings have been contradictory.
Some researchers such as Cochran, Mays, Bowen et al. (2001) have speculated that lesbians may have an increased risk for developing breast cancer. Researchers have found that lesbians (between the ages of 18 and 75) were more than likely than women overall to have several behavior risk factors for breast cancer and gynecological cancer.
In 2001, Rosenburg’s study analyzed various questionnaire responses from surveys conducted from 1987 and 1996, in which 11, 876 were involved in the study. These responses were compared to the national average of women. The study indicated that more than 12% of lesbians reported to having history of problems with alcohol. Lesbians were also more likely than average to use tobacco (21% vs. 16%) and to have used tobacco in the past. They were also less likely to use birth control pills. In addition, lesbians overall were less likely to be covered by health insurance (86% vs. 93%), which also meant they were less likely to have undergone cancer screenings. Only 73% reported having recent pelvic examinations, compared to the standard estimate of 87% for women nationally, and lesbians in their 40s were less likely than women overall ever to have had a mammogram (Rosenburg, 2001).
The most cited risk factors in the research on lesbians and breast cancer and gynecological risk are:
Cigarette smoking - studies have indicated that lesbians smoke cigarettes at a drastically greater rate than of heterosexual women.
Alcohol use- Some investigations have stated higher frequencies of heavy drinking among lesbians than heterosexual women.
Obesity- Some research report that lesbians are more likely to be overweight or have a BMI higher than 25.
Pregnancy- Lesbians are less likely to have biological children before the age of 30. (Early pregnancy and the use of birth control pills are known to decrease risk of breast cancer.)
