Cumulative incidence rates of ipsilateral and contralateral invasive breast cancer and 95% confidence intervals in 24 716 women with unilateral ductal carcinoma in situ (DCIS) detected as a result of screening between April 2000 and March 2014 and who had surgery. Women with unknown laterality of subsequent invasive cancer were excluded, as were women with oestrogen receptor positive DCIS and recorded as receiving endocrine treatment. BCS+RT=breast conserving surgery, radiotherapy recorded; BCS-RT=breast conserving surgery, radiotherapy not recorded. *Number of ipsilateral invasive breast cancers during interval. †Number of contralateral invasive breast cancers during interval
