Recent clinical trials have shown that 90 percent of early stage breast cancer patients over age 70 do not benefit from radiation after breast-conserving surgery.
Radiation treatment uses high-energy rays to kill breast cancer cells. The rays are directed at the area where the tumor appeared. Two common types of radiation treatment are external beam radiation and internal beam radiation.
Radiation therapy is a form of cancer treatment that uses high energyX-rays to kill cancer cells while minimizing damage to healthy cells. When used for breast cancer treatmentradiation is delivered to the affected breast and, in some cases, to the lymph nodes under the arm or at the collarbone.
