Triple-Positive PALB-2 Breast Cancer in a 27-Year-Old Male-to-Female Patient.

Study design: Case Report
Abstract: Introduction: There is a paucity of literature describing breast cancer prevention and screening guidelines in transgender patients. As more patients undergo gender-affirming care, breast cancer screening guidelines must be solidified for transgender patients. While there are no published incidence rates of breast cancer in the transgender population, case reports continue to underscore the prevalence of breast cancer in transgender females. Methods: A 27-year-old transgender woman with a family history of breast cancer and personal gender-affirming hormone therapy for 9 years was diagnosed with stage 3 invasive ductal carcinoma. The patient presented with a palpable breast lump and had never undergone breast imaging. Conclusions: genes have an increased risk for breast cancer. Hormonal treatment is often used alongside gender-affirming surgeries for development of female secondary sex characteristics in male-to-female patients. Although hormone therapy can have gender-affirming benefits, the increased lifetime exposure to estrogen and progesterone can increase the risk of breast cancer. Mammography guidelines for transgender patients vary by age, familial and genetic risk, as well as duration of hormone therapy. Three current organizations have published mammographic screening guidelines for transgender patients: the University of California San Francisco, the World Professional Association for Transgender Health, and the American College of Radiology. Future research should focus on substantiating these guidelines with greater data to produce evidence-based recommendations to guide the care of transgender patients.
