You can share with us your questions about Radiotherapy, which is applied in two ways, externally and internally. Treatment centers generally give priority to external radiotherapy. With the help of technological devices to be used, rays are sent to cancerous cells. Thanks to three-dimensional conformal radiotherapy, which has been preferred in recent years and applied with the help of more technological devices, the highest doses are provided. Your doctor will make the decisions about which method and device will be more appropriate.
