Every year 900 Australian AYAs (15-25 yrs old) are diagnosed with cancer and the subsequent treatment and interruption of development has long-term consequences. Compared to young people with no cancer, AYA survivors have greater chronic disease, disability and mental health concerns. Also, AYA survivorship has lacked progress compared to paediatric and older adult cancers. Against this backdrop, AYAs with cancer have unique survival challenges – medically, psychosocially and economically. Specific AYA survivorship services must be developed to address unmet needs, offer equitable access and provide developmentally tailored support. This project will investigate successful global AYA cancer survivorship models.
