The natural history of screen-detected breast cancers is not well understood. In this Swedish study, women aged 40-49 years were screened every year and women aged 50-74 were screened every 2 years. All women were followed up after 6 years as well as the control group who went 4 years without screening. The study authors believed that many invasive breast cancers detected by repeated mammography screening do not persist at the end of the 6 years, suggesting that the natural course of many of the screen-detected invasive breast cancers is to spontaneously regress.
