Partial Breast Irradiation
What Are the Advantages of Partial Breast Irradiation?
Partial breast irradiation is able to deliver radiation therapy at higher doses to a more precise location of the breast. With partial-breast irradiation, you are able to receive radiation in as few as five days versus six weeks (as was the case with whole breast irradiation). Partial-breast irradiation also minimizes radiation exposure to the entire breast, skin, ribs and lungs. It has been shown that partial-breast irradiation will lower the chances of breast cancer recurring.
How Does Partial Breast Irradiation Work?
After the surgical lumpectomy is completed, a small balloon-like catheter is inserted into the lumpectomy cavity. This catheter remains 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 that delivers radiation directly through the catheter to the tumor site and the area immediately surrounding the cavity.
Treatment occurs 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 due to the reduction in overall treatment time.
