Narrator: This is Science Today. A new radiation technique for breast cancer is being successfully implemented at the University of California, Davis Cancer Center. UC Davis is part of the National Cancer Institute Centers, where such advances are often first available. The treatment involves implanting a catheter into the site where a tumor was removed and then applying radiation directly to that cavity. Dr. Jyoti Mayadev, a radiation oncologist at UC Davis, says they're trying to preferentially put radiation where it's needed most.
Mayadev: And so this catheter or form of partial-breast radiation program we have at UC Davis allows us to do just that. In traditional breast cancer radiation, we have to radiate the entirety of the breast as well as the chest wall, including the lung which is not optimal due to the potential of long-term side effects.
Narrator: Research has found that the results with the new technique are similar to whole-breast radiation, which decreases the chance of tumor recurrence by more than 60 percent. For Science Today, I'm Larissa Branin.
