2) Radiotherapy
on the other hand, is the practice of using a powerful type of radiation called ionizing radiation to kill the cancer cells. The rays are aimed only at the part of the body where the tumor resides to minimize unwanted side effects. When it comes to the treatment of mesothelioma with this modality, radiotherapy is usually employed after surgical resection of the tumor to ensure the destruction of all cancer cells and to decrease the chances of it growing back. In patients who cannot tolerate a surgical operation, whether due to advanced age or severe disease, radiotherapy can be used as a palliative treatment to reduce the size of the tumor and thus decrease the symptoms caused by it to some extent.
