Radiation Therapy Mesothelioma - Some Hope

Radiation therapy mesothelioma is the use of high-dose radiation to destroy or reduce malignant tumors. The radiation used is high-energy x-rays, neutrons, photons, cobalt or other radiation sources. Radiation can be delivered by way of internal radiation therapy, external-beam radiation therapy, or radioisotopes. Internal radiation therapy delivers radiation through sealed thin plastic tubes, needles, wires, or catheters and placed near or into the tumor being targeted. External-beam radiation therapy delivers radiation through a machine directing a beam of radiation. Radioisotopes are materials that produce radiation. In a series of treatments the radiation damages cancer cells so they no longer divide or multiply. The tumor is thereby reduced in size.
