Skin cancer and skin cancer risk behaviors among sexual and gender minority populations: A systematic review.

BACKGROUND

Individuals of sexual and gender minorities may have different lifetime risk of skin cancer and ultraviolet radiation exposure than heterosexual persons.

OBJECTIVE

To systematically review the prevalence of skin cancer and behaviors that increase risk of skin cancer among sexual and gender minority populations.

METHODS

We performed a systematic literature review in PubMed/MEDLINE, Embase, Cochrane, and Web of Science, searching for articles through October 18, 2019, that investigated risk of skin cancer and behaviors among sexual and gender minority populations.

RESULTS

Sexual minority men have a higher lifetime risk of any skin cancer (odds ratio range: 1.3-2.1) and indoor tanning bed use (odds ratio range: 2.8-5.9) compared with heterosexual men, whereas sexual minority women may use indoor tanning beds less frequently than heterosexual women and do not have an elevated risk of lifetime history of skin cancer. Gender-nonconforming individuals have higher lifetime prevalence of any skin cancer compared with cisgender men.

LIMITATIONS

Most variables rely on self-reporting in their original studies.

CONCLUSIONS

Sexual minority men disproportionately engage in use of indoor tanning beds, which may result in increased lifetime risk of skin cancer. Recognition of this risk is important for providing appropriate screening for patients in this population.
