In recent years remarkable progress has been made towards the understanding of proposed hallmarks of cancer development and treatment however with its increasing incidence, the clinical management of cancer continues to be a challenge for the 21st century treatment modalities comprise of radiation therapy, surgery, chemotherapy, immunotherapy and hormonal therapy. Radiation therapy (RT) is the chief non-surgical method to control malignant tumour. RT has advanced in both methodological and biological aspects over the past few decades. RT remains an important component of cancer treatment with approximate 50% of all cancer patients receiving radiation therapy during their course of illness. it contributes toward 40% of curative treatment for cancer. In radiation therapy uses high energy particles or waves such as X- rays, Gamma rays, cancer cell. Our cell normally grows and divide to form new cell but cancer cells grow and divide faster than most normal cells. Radiation work by making small breaks in the DNA inside cells. these breaks keep cancer cells from growing and dividing and cause them to die. Nearby normal cell can also be affected by radiation, but most recover and go back to working the way they should. Some of the latest advances in radiotherapy, including 3-D conformal radiotherapy, Intensity modulated radiotherapy and Image-guided radiotherapy help define the target area with high accuracy and effectively deliver precise doses of radiation causing only minimal damage to healthy cells, tissues and organ. This paper present the history and status of RT studies, and principal of radiotherapy. And also we represent the recent treatment strategies of radiation therapy.
