Should starting-age for breast cancer screening depend on risk?
The authors of a population-based study think it should
An analysis of more than five million Swedish women has identified starting ages for breast cancer screening based on family history of the disease.
German-led researchers used Swedish registry data on nearly 5.1 million women, including some 119,000 who were diagnosed with invasive breast cancer.
Most of the women with breast cancer (86%) had no family history of the disease in first-degree or second-degree relatives.
Lifetime breast cancer risk for the 14% of women with family histories of breast cancer ranged from 11% to 23%, while it was 9% for the women with no family history of breast cancer.
