New study supports DCIS breast cancer treatment
Mar 23, 2011
Ductal carcinoma in situ (DCIS) is a form of non-invasive breast cancer for which treatment is controversial but supported by a new study from the Stanford Cancer Center, according to the Seattle Times.
As a non-invasive breast cancer, DCIS cancer cells are only found in the milk ducts of the breast.
The new study, which looked at approximately 2,600 women over the span of five years, shows that treating DCIS early on with drugs and chemotherapy led to lower risks of cancer later on.
"We're coming into an era where treatments are going to be more tailored to the individual. Women who were treated by lumpectomy alone, 65 percent of them didn't have a recurrence of cancer," said Dr. Irene Wapnir, the study's principal investigator and chief of breast surgery at the Stanford Cancer Center.
About 200,000 women in the U.S. are diagnosed with breast cancer. The disease is the most frequent cancer in American women. Yearly mammograms are recommended for women over the age of 40.
