The diagnosis of breast cancer affects the physical and psychological behavior of each patient. It is necessary to keep in mind the patient's fear, anxiety and depression in relation to the operation. Furthermore, psychological behaviors can affect the physical side effects of patients, and these side effects usually result in a longer recovery. Complications from surgery include pain, seroma, hematoma, infection, fatigue, limited shoulder range of motion, and lymphedema. The physiotherapist conducts an assessment according to the SOAP model, fills in all the necessary components and measurements and, together with the patient, creates a plan and program of physiotherapy procedures. Patients should be encouraged to actively cooperate in their recovery, and physiotherapy procedures can help reduce the negative effects of all complications. Physiotherapy procedures begin immediately after the operation in order to prevent any further complications and enable the return to activities of daily life.
