RADIATION THERAPY IN CANCER DIAGNOSIS AND TREATMENT
Mahadev Govindrao Tate* and Gayatri Mohan Saini
Radioisotopes are unstable atomic isotopes that give off radiation spontaneously. They can be measured by a suitable apparatus at amounts as small as one-billionth of a gram. Thus, they can be safely used in small amounts as in the body. Today, radioisotopes are used both diagnostically and therapeutically in medicine. Radiation therapy is used against many types of cancer. About 60% of cancer cases require radiation therapy. Carcinomas are an example of a type of cancer that often has high division rates. These types of cancer tend to respond well to radiation therapy. Radiation therapy is delivered in a 'Radiation oncology' department. More than 14 million new cases of cancer are diagnosed globally each year; radiation therapy (RT) has the potential to improve the rates of cure of 3.5 million people and provide palliative relief for an additional 3.5 million people. The success rate of radiation therapy is near about 80% for many cancers.
Keywords: Radioisotopes, Radiation therapy (RT).
