PEORIA, Ill. -- A new Canadian study is sparking some controversy over mammograms.
After a 25 year study, Canadian researchers found routine mammograms did not reduce breast cancer death rates.
A spokesperson for the Susan G. Komen Memorial Affiliate in Peoria said no one can argue that mammograms don't save lives.
And while completing a study takes years, it doesn't always take into account the latest technology.
"When you introduce old technologies into a study, in some cases that makes some of that information, not invalid but irrelevant," said Philip Lockwood with the Susan G. Komen Memorial Affiliate.
Komen officials also said while the study may be trying to discredit mammograms, the death rate of people diagnosed with breast cancer has dropped dramatically.
