It is a kind of particle therapy that offers targeted treatment, unlike any other radiation treatment. Proton Beam Therapy is effective for the treatment of cancers like skull base tumors, pediatric cancers, brain tumors, and prostate cancers.. CyberKnifie is another powerful radiation therapy used for cancer treatment. It is a lightweight linear accelerator placed on a robotic arm. Real-time images allow patient movement tracking with high accuracy. The CyberKnife also uses real-time X-rays to find the exact position of the lesion during treatment.

A radiation oncologist is a doctor who uses radiation for the treatment of cancer. Radiation oncologists may use radiation to treat certain benign diseases like benign (non-cancerous) tumors. Radiation oncologists also work with other physicians like surgical oncologists, medical oncologists, medicine subspecialists, and are a part of the cancer team. Radiation oncologists evaluate the nature of cancer and use a wide spectrum of treatment techniques, such as hyperthermia, external beam radiotherapy, and radioactive implantations. They monitor the overall health of cancer patients and suggest and establish long-term relationships with patients post-treatment.
