The current rise in structural hostility towards transgender and gender diverse individuals highlights the importance of appropriate and affirming care for this medically marginalized community. In cancer genetics, specific factors such as medical transition and psychosocial impacts alter the approach to, and requirements of, genetic counseling for trans patients. To support the unique needs of trans and gender diverse patients in hereditary cancer genetic counseling, PhenoTips hosted an international panel of cancer genetic counselors with advocacy and research specialties in inclusive genetic counseling practices for LGBTQ+ patients.
