Radiation therapy is the use of high-energy X-rays to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external radiation therapy) or from putting materials that produce radiation (radioisotopes) through thin plastic tubes into the area where the cancer cells are found (internal radiation therapy, also called brachytherapy). Radiation therapy is often used in combination with surgery or chemotherapy or both.
Radiation following surgery for stages II or III non-small cell lung cancer may reduce the risk of cancer recurrence in the chest, but long-term survival rates are not significantly improved because cancer may have already spread to other areas of the body.
Dr. Shamsuddin Khwaja specializes in using the Cyperknife Robotic Radiosurgery System in order to provide a non-invasive alternative to surgery for the treatment of both cancerous and non-cancerous tumors. The CyberKnife System is the world’s first and only robotic radiosurgery system designed to treat tumors throughout the body non-invasively. It provides a pain-free, non-surgical option for patients who have inoperable or surgically complex tumors, or who may be looking for an alternative to surgery.
