Radiation therapy is the type of cancer treatment using radiations (beams) of high intensity to kill cancer cells. Radiation therapy damages the cell by destroying their genetic material while doing these there are some normal cell also gets destroyed. The rays that are used are x-rays, gamma-rays, proton rays and neutron rays. Radiation therapy can be used for more than half of the cancer types. Radiation therapy journals covers the use of radiations in the treatment of cancer. Related journals of Radiation therapy Stereotactic Radiation Therapy, Nuclear Medicine and Radiation Therapy, Radiotherapy and Oncology, Radiotherapy in Practice, Radiation Oncology, Radiology & Radiation Therapy. Radiation therapy kills cancer cells by damaging their DNA, Cancer cells whose DNA is damaged beyond repair stop dividing or die. When the damaged cells die, they are broken down and eliminated by the body’s natural processes. Radiation therapy has a side effect i.e. along with the dmage of cancer cells it also damages normal cell.
