Showing Cyberknife Cancer Therapy

Traveling From UK

Cyberknife cancer therapy is a non-invasive treatment for cancerous tumours that cannot be removed with surgery. The cyberknife machine is used to give stereotactic radiotherapy. It differs to gamma knife therapy as the patient is not required to keep completely still. The machine is able to accurately locate the site of the tumour and adjusts to any movement by frequently scanning the area. This means there is little damage to the healthy tissue and it can be carried out on areas of the body which move such as the lungs. The patient first has a CT and MRI scan to locate the tumour. This information is then transferred onto the cyberknife machine’s computer. This computer controls the robotic arms that deliver the radiation. The treatment takes 30 to 90 minutes and patients do not need anesthesia. This is a very new treatment and it is still being researched to find out which cancers can be treated by cyberknife therapy.
