Breast cancer risk in transgender people receiving hormone treatment: nationwide cohort study in the Netherlands

Breast cancer risks for trans women are considered to be the same as cis women. The same screening protocols should be used for both cis and trans women.

This study showed an increased risk of breast cancer in trans women compared with cisgender men, and a lower risk in trans men compared with cisgender women. In trans women, the risk of breast cancer increased during a relatively short duration of hormone treatment and the characteristics of the breast cancer resembled a more female pattern. These results suggest that breast cancer screening guidelines for cisgender people are sufficient for transgender people using hormone treatment.
