Local doctor talks about mammogram study

A medical study in Canada has raised serious questions about the effectiveness of mammograms.

During the course of 25 years, doctors kept track of 90,000 women. The study concluded that there was no difference in the rate of breast cancer deaths between the women who had mammograms and those who did not.

Dr. Helen Mabry is a breast surgeon oncologist at the University of Toledo Medical Center.

"This study brings up the possibility of overtreatment, and some women are experiencing unnecessary treatments," Dr. Mabry said.

Doctors in the United States recommend that women start getting annual mammograms at age 40.
