Transgender people are a growing population with specific healthcare needs, barriers to care, and disease risk factors. Cultural competencies for working with transgender people in healthcare settings are essential to reduce barriers to care and combat the associated health disparities. Genetic counselors support their patients to understand and manage medically and personally complex life events and decisions. A genetic counselor caring for a transgender patient or a patient with a transgender relative will therefore require specific cultural competencies and medical knowledge that may not have been covered in their training. Transgender health is also a relatively young field in which new insights may quickly become fundamental. The present paper therefore provides an overview of current best practices for culturally sensitive working with transgender patients, and an introduction to the additional considerations for assessment of disease risk in transgender people. Guidance on how to ensure communication with patients and other stakeholders is inclusive and affirming of transgender identities, is offered. Medical interventions used for gender transitions are described, and their (potential) effects on cancer and cardiovascular disease risk are discussed. Furthermore, the effects of sociocultural risk factors such as minority stress are outlined. In sum, we invite the reader to consider the specific biological, psychological, and social context of the consultation. Finally, we explore culturally competent approaches to pedigree charting and physical examinations with transgender people and provide recommendations for practice.

Purpose of Review To best support all patients with inherited cancer risk, we must broaden our scope of practice to consider the needs of the transgender and gender diverse (trans) community. We considered best practice for supporting trans patients including tailored risk assessments and management recommendations. Recent Findings There is limited literature considering trans patient care in cancer genetics. Small case studies have highlighted how medical transition and cancer risk–reducing options intersect with the need for individualised care. Studies have also shown that cancer genetics professionals do not feel prepared to support trans patients. Summary Patient-centred care for trans patients relies on a multidisciplinary team (MDT) engaged in shared decision-making. National guidelines are needed to standardise access to appropriate discussions around risk-reducing options and screening. International collaborative research is required to provide empiric data on the impact of gender-affirming treatments on cancer risk, and more experiential data is needed from trans patients accessing cancer genetics services. Finally, education and training in this area should be formally embedded for all cancer genetics professionals.
