Following publication of the original article [1], the authors flagged the following error in the '3. Formula to estimate the contralateral breast cancer risk using PredictCBC-2.0A' section of additional file 1: ‘+ 0.065 × I[Radiotherapy to the breast = yes]’ had been written in place of ‘− 0.065 × I[Radiotherapy to the breast = yes]‘.

The file has since been corrected. The authors thank you for reading and apologize for any inconvenience caused.
