Telemedicine is defined as the practice of medicine from a distance, without the doctor's physical presence. Teleoncology consist of telediagnosis, teleconsultation, telepathology, telesurgery, distant help in computer-aided radiotherapy planning and telefollow-up. In this paper, we present the wide range of possibilities in providing cancer care at a distance. The theoretical and practical aspects of teleoncology and its current as well as future role in a multidisciplinary approach to cancer patients are discussed.
