Transgender women on hormones have elevated breast cancer risk

But the absolute overall risk is still low in transgender people

Transgender women on gender-affirming hormone treatment are at increased risk of breast cancer compared with cisgender men, a Dutch study has shown.

In a retrospective, nationwide cohort study, researchers in the Netherlands compared incidence of invasive breast cancer in 2260 transgender women and 1229 transgender men receiving hormone treatment with incidence in the general population.
