Radiation Therapy Options
Conventional External Beam Radiation
- High-energy beams pass through the skin to treat the entire breast and eliminate any cancer cells that could remain after a breast cancer tumor is removed (lumpectomy).
- A daily dose of radiation is delivered for 5-7 weeks.

MammoSite® 5-Day Targeted Radiation Therapy
- Radiation therapy is delivered from inside the breast directly to the area where cancer is most likely to recur.3
- Targeting the area from the inside out reduces the exposure of normal, healthy tissue and organs to radiation.
- Using a highly targeted dose, radiation treatment is complete in 5 days.
- Side effects such as skin burning and fatigue are minimized.
- Most women continue normal activities through and immediately following treatment.
Delivering radiation from inside the body – also called “brachytherapy” – is used to treat many cancers. For example, use of brachytherapy as a treatment of prostate cancer goes back as far as 1917, and has been the standard of care for prostate cancer for several decades.
