Despite surgical removal of ductal carcinoma in situ (DCIS), recurrences still occur. This retrospective cohort study evaluated the risk of invasive recurrence following surgery and investigated factors which may be predictive of recurrence. We specifically investigated invasive recurrence with respect to mode of detection of DCIS. Patients whose DCIS was detected outside of the NHS Breast Screening Programme have a higher risk of subsequent ipsilateral invasive breast cancer than those whose DCIS is detected through screening. There is no significant difference in risk of subsequent contralateral invasive recurrence according to mode of detection.
