Cancer in people who identify as lesbian, gay, bisexual, transgender, queer, or gender‐nonconforming

Abstract

AbstractBackgroundIndividuals who identify as lesbian, gay, bisexual, transgender, queer, intersex, or gender‐nonconforming (LGBTQ+) experience discrimination and minority stress that may lead to elevated cancer risk.MethodsIn the absence of population‐based cancer occurrence information for this population, this article comprehensively examines contemporary, age‐adjusted cancer risk factor and screening prevalence using data from the National Health Interview Survey, Behavioral Risk Factor Surveillance System, and National Youth Tobacco Survey, and provides a literature review of cancer incidence and barriers to care.ResultsLesbian, gay, and bisexual adults are more likely to smoke cigarettes than heterosexual adults (16% compared to 12% in 2021–2022), with the largest disparity among bisexual women. For example, 34% of bisexual women aged 40–49 years and 24% of those 50 and older smoke compared to 12% and 11%, respectively, of heterosexual women. Smoking is also elevated among youth who identify as lesbian, gay, or bisexual (4%) or transgender (5%) compared to heterosexual or cisgender (1%). Excess body weight is elevated among lesbian and bisexual women (68% vs. 61% among heterosexual women), largely due to higher obesity prevalence among bisexual women (43% vs. 38% among lesbian women and 33% among heterosexual women). Bisexual women also have a higher prevalence of no leisure‐time physical activity (35% vs. 28% among heterosexual women), as do transgender individuals (30%–31% vs. 21%–25% among cisgender individuals). Heavier alcohol intake among lesbian, gay, and bisexual individuals is confined to bisexual women, with 14% consuming more than 7 drinks/week versus 6% of heterosexual women. In contrast, prevalence of cancer screening and risk reducing vaccinations in LGBTQ+ individuals is similar to or higher than their heterosexual/cisgender counterparts except for lower cervical and colorectal cancer screening among transgender men.ConclusionsPeople within the LGBTQ+ population have a higher prevalence of smoking, obesity, and alcohol consumption compared to heterosexual and cisgender people, suggesting a higher cancer burden. Health systems have an opportunity to help inform these disparities through the routine collection of information on sexual orientation and gender identity to facilitate cancer surveillance and to mitigate them through education to increase awareness of LGBTQ+ health needs.
