The aim of this study was to describe breast ductal carcinoma in situ (DCIS) incidence trends in women in the Girona province during a period of 25 years. The influence of age, use of mammography and implementation of the breast cancer screening programs was explored. Incidence of subsequent invasive breast cancers (IBC) and DCIS treatment was also considered. ⋯ The upward trend of DCIS was mainly related to an increase in mammography use either opportunistic or as a result of screening implementation.
