More Mammogram Controversy

Posted: Updated:

A Canadian study finds annual mammograms do not reduce breast cancer deaths among middle aged women.

Researchers compared breast cancer diagnosis and death rates among women aged 40 to 59 who either did or did not undergo yearly mammograms. The women in both groups received annual physical breast exams or usual women's care.

Five years later, the mammogram group had a similar number of breast cancer diagnoses and deaths as the non-mammogram group. The results also revealed 22-percent of mammogram detected cancers were harmless and would not have caused symptoms or death during the patient's lifetime.
