This article was designed to help the practitioners by proposing the recommendations for diagnostics and evaluation of the severity of complications of the radical treatment of the patients presenting with breast cancer, stomach cancer, endometrial cancer, cervical cancer, bone sarcoma (osteosarcoma, chondrosarcoma, periosteal sarcoma, et al.). The indications for medical rehabilitation of the patients with these problems are described with special reference to their treatment under the conditions of a multi-disciplinary hospital depending on the type and severity of complications of the radical treatment. The results of the long-term investigations and analysis of a large number of observations were used to substantiate the application of the available physiotherapeutic technologies for the medical rehabilitation of the oncological patients belonging to clinical group III.
