New research on benefits of breast cancer screening

Posted: Updated:
LOS ANGELES -

Some women over 65 diagnosed with low-grade breast cancer that is fueled by hormones may be able to avoid radiation. New research presented at the San Antonio Breast Cancer Symposium looked at hundreds of older patients treated with or without radiation and found no difference in overall survival and small differences in recurrence rates after five years.

There have been a lot of recent studies with varying results on the benefits of mammography. Researchers for the American Cancer Society took another look at the data from four large studies. They say when they focused the findings specifically on women over 50, there was a clear benefit to screening.

"All of them show within this age group a consistent benefit in reducing the mortality from breast cancer," said Dr. Freya Schnabel of NYU Langone Medical Center.

Studies show that African-American women are more likely to get aggressive breast cancers and now new research finds vigorous exercise may offer protection.

"Women who over the course of a long period of time exercised three or more hours per week had a 47 percent reduction in the risk of developing these more aggressive types of breast cancer," Schnabel said.

Women in the study did exercise including brisk walking, tennis and aerobics.

In the exercise study, researchers looked at about 45,000 women over 30.
