Medical Experts Debate New Breast Cancer Screening Guidelines

The U.S. Preventive Services Task Force now recommends women begin screening for breast cancer at age 40 instead of 50.
There is disagreement among medical organizations about when women should start getting mammograms, causing confusion.
Earlier screening finds more cancers but also leads to unnecessary biopsies and procedures that stress patients.
The new guidelines fail to provide specific advice for minority women and call only for more research.
The goal should be to detect cancer thoughtfully and determine appropriate responses.
