Radiation Treatment Options


External Beam Radiation Therapy


Beams from special X-ray machines, called linear accelerators, are aimed at the breast from outside the body. During your treatment, a beam of radiation (high-energy x-rays or electrons) is directed through the skin to destroy cancerous cells. This form of radiation therapy may be recommended after either breast conserving surgery or mastectomy.


Treatment is typically given on a daily basis, from Monday through Friday, over a period of approximately 6 weeks. Certain women who have undergone breast conserving surgery may be able to have treatment delivered over approximately 3 weeks.


Accelerated Partial Breast Irradiation


This form of radiation therapy, also known as breast brachytherapy, is an option for certain women who have undergone breast conserving surgery for early stage breast cancer or ductal carcinoma in situ (DCIS). Breast brachytherapy is a more localized means of treatment than external beam radiation therapy. Therefore, healthy breast, skin, rib, muscle, lung and heart tissue is exposed to lower doses of radiation. Treatment involves placing one or more catheters into the breast.  Internal radiation treatments are delivered twice daily for 5 days.
