Canadian study casts doubt on mammograms

(WZZM) - For years, we've heard mammograms can save women from breast cancer, now another study is casting doubt on their value.

The Canadian study included thousands of women between ages 40 and 59. Half received a mammogram, the other half did not.

Over the 25 year study, of the women who had the mammogram, about 3,200 breast cancer diagnoses were made and 500 patients died. For the other group, about 3,100 cases of breast cancer were diagnosed through self breast exams and about 500 of those patients died as well.

Researchers say because the results are about the same for both groups, mammograms have no obvious benefit to women. They also say one in every five cancers detected by a mammogram was not a threat and did not require chemo, radiation or surgery.
