Radiation Oncology for Early Detection of Cancer

Cancer is considered to be the number two cause of death for US residents. Globally people are trying to find out different methods for early detection and treatment of the disease. New treatment technologies, such as radiation therapy are being developed and researched to reduce the cancer mortality rates.

Radiation oncology is one such treatment based on radiation therapy that is used for treating cancerous tumors via radiation. Radiation oncology involves specialized treatment methods which implement latest sophisticated technologies and equipments to deliver precise beams of radiation to the affected area without affecting the surrounding areas.

The oncologist uses multitude of specific therapy methods for treating cancerous tumors via radiation. Intense Modulated Radiation Therapy and Tomo Therapy are some of the effective methods for issuing precise doses of radiation. A radiation oncologist uses radiation therapy as the main modality of treatment for treatment of cancer patients. The radiation oncologist decides the form of radiation therapy that might be apt for a particular type of cancer. Radiation can be   given as a curative modality or to relieve symptoms in patients with incurable cancers. Radiation can also be given in-combination with surgery or chemotherapy.
