Background The increasing incidence of cancer, coupled with improved survivorship, has increased the demand for cancer follow-up care and the need to find alternative models of care. International and national guidelines advocate for including general practitioners (GP) in cancer follow-up care. Barriers to implementing shared care into practice include having clinical assessment protocols for GPs, and suitable health technology to allow two-way communication to enable oncologists to continue overseeing care.
