Dear Colleague:
Name of Practice is pleased to offer MammoSite® 5-Day Targeted Radiation Therapy as a treatment option
for patients with early stage breast cancer (see reverse for recommended guidelines for Patient Selection).
MammoSite Therapy offers patients with early stage breast cancer the opportunity to complete their
radiation treatment in 5 days, as opposed to traditional radiation therapy which can take 6 to 7 weeks.
MammoSite® 5-day Targeted Radiation Therapy works from inside the breast, directly targeting the area
where cancer is most likely to recur.1
Moreover, MammoSite Therapy can work with adjuvant chemotherapy. Chemotherapy can be done
before or after MammoSite 5-Day Targeted Radiation Therapy, enabling you to provide a
comprehensive treatment plan for your early stage breast cancer patients.
Five year follow-up data for MammoSite Therapy has shown the following results:
5-Year Initial Clinical Trial Results (N=43)2

No local recurrences.
83.3% of patients had good/excellent cosmetic results.
100% of patients would recommend MammoSite Therapy to a friend or family member.
100% of patients would use MammoSite Therapy if they had to do it over.
We are excited about offering MammoSite 5-Day Targeted Radiation Therapy. We hope you will feel free
to contact us if you should have further questions or if you would like to discuss the appropriateness of this
technique for an early stage breast cancer patient.
Sincerely,
