Screening Guidelines

Although data on transgender patients is limited, breast cancer screening guidelines in this population are evolving. 

Transgender women have a high prevalence of dense breasts, which is an independent risk for breast cancer. Increased breast density is also associated with increased rates of false negative mammograms.  

Transgender women differ from non-transgender women in the length of exposure to estrogens as well as variable exposure to progestogens. Therefore, it is recommended that screening not begin in transgender women until after a minimum of five years of feminizing hormone use, regardless of age.

Some providers may choose to discuss the risks and unknowns with patients and delay screening until after up to 10 years of feminizing hormone use, regardless of age. If you are unsure when to start screening, discuss this with your provider, or ask about consulting with one of our radiologists.
