Radiation therapy is a method of locoregional treatment of cancer using radiation to destroy cancer cells by blocking their ability to multiply. The irradiations destroy all the cancer cells while sparing healthy tissue to the periphery.
Radiotherapy is used in more than 50% of patients with cancer. Combined with surgery, this is the most common cancer fighting treatment. It can be used alone or in combination with surgery and chemotherapy. It is usually offered as an outpatient treatment that is to say, without hospitalization. The sessions are short and there are fewer side effects during chemotherapy. Breast cancer is a cancer that is very sensitive to radiation.
