Partial Breast irradiation is a minimally invasive method of delivering radiation therapy to breast cancer patients who have recently undergone a lumpectomy. With this technology, breast cancer can be treated in five days instead of six to seven weeks. Methodist Sugar Land Breast Center offers both Mammosite and Contura treatment modalities.
Your Breast Care Team will determine if you are a candidate for partial breast irradiation based on your individual case.
Whole-breast irradiation has been the standard treatment until recently for women who have recently had a lumpectomy. It has been proven that partial-breast irradiation will lessen the chances of breast cancer recurring without subjecting the entire breast to radiation. Partial breast irradiation is able to deliver radiation therapy at higher doses to a more precise location of the breast. With these new capabilities, the patient is able to receive radiation in as little as 5 days versus the normal 6 weeks while minimizing radiation exposure to the entire breast, skin, ribs and lungs.
After the surgical lumpectomy is completed, a small balloon-like catheter is inserted into the lumpectomy cavity. This catheter will remain in place during radiation planning and for the duration of the five-day treatment course. During the actual treatment process, the catheter is attached to a high-dose rate machine which delivers radiation directly through the catheter to the tumor site and the area immediately surrounding the cavity.
The patient will undergo this treatment twice a day for five days. At the end of the treatment course, the balloon is deflated and permanently removed. Partial breast irradiation is becoming a suitable and convenient option for patients due to the reduction in overall treatment time.
