TO SCREEN OR NOT TO SCREEN?
What are the pros and cons of breast screening?
Lucy, Glasgow Breast screening is offered every three years for women aged 50 to 70, although younger or older women may also be offered it. Mammograms use X-ray imaging to detect breast cancer before a lump can be felt, but they also pick up harmless changes. A recent review found that, for every 1,000 women screened over 20 years, about five breast cancer deaths are prevented at the expense of around 17 women who are diagnosed and treated for a cancer that would never have caused a problem. Also, 200-plus women will experience distress due to false positive findings.
