Each year approximately 3,900 adolescents and young adults aged 18 to 39, AYAs, are confronted with a cancer diagnosis. Together they make up 3.5% of the total number of cancer patients. This patient group requires additional support due to the unique physical, psychological and social challenges faced by young adults with cancer. Testicular cancer is the most common in young men. From a clinical point of view nutrition and exercise, family and friends, work/education and reintegration, insurance, emotions and sexuality are common themes among patients with testicular cancer. Age-specific AYA care should therefore be an integral part of the care of patients with testicular cancer. © 2023, The Author(s).
