Recent increase of breast cancer incidence among women under the age of forty.
Using data from the Geneva Cancer Registry, we found that in 2002-2004, breast cancer incidence in women aged 25-39 years increased by 46.7% per year (95% CI: 7.1-74.0, P=0.015), which surveillance or detection bias may not fully explain.
