Radiation for Breast Cancer

Learn about the new radiation treatment options available at the MedStar Health Baltimore Cancer Network in the videos below: 


Breast cancer treatments generally involve some combination of radiation, surgery, chemotherapy, hormone therapy, and targeted therapy. Often, radiation destroys cancer cells that might be left behind after surgery.

MedStar Health brings together a team of experts from a variety of specialties to evaluate your particular case and determine the best plan for you and your family. We tailor every approach we use to your specific needs. We target the radiation to spare as much healthy tissue as possible.

Multiple radiation techniques and technologies can be used to treat breast cancer, including:

3D Conformal Radiotherapy

This therapy sculpts radiation beams to the shape of a tumor and is ideal for irregularly shaped tumors or those close to healthy tissues and organs. Our specialists view a tumor in three dimensions with the help of advanced imaging and deliver radiation beams to the tumor from several directions.

Intensity Modulated Radiation Therapy (IMRT)

IMRT sends tiny beams of radiation that conform to the shape of the breast and the area of risk. This technique allows for different areas to receive different highly-sculpted doses of radiation. IMRT helps protect healthy tissue and critical nearby organs from unnecessary radiation exposure and reduces skin damage around the breast.

Accelerated Partial Breast Irradiation (APBI)

APBI is an advanced method of internal high-dose radiation used for select breast cancer patients after a partial mastectomy/lumpectomy. It delivers radiation to the area where the tumor was removed and eliminates the need for whole breast radiation.

External beam radiation therapy for Partial Breast Irradiation (PBI)

This procedure uses a linear accelerator to aim high-energy radiation beams at the tumor from outside your body. Our specialists treat as small an area of your breast as possible to avoid causing unnecessary damage to your healthy tissue.

Intraoperative Radiation Therapy (IORT)

It is a single-dose radiation alternative for women with early stage breast cancer. Standard treatment can involve five to six weeks of treatment; with IORT, a single dose is delivered in the operating room immediately following a partial mastectomy/lumpectomy.
