From: The clinical significance of oestrogen receptor expression in breast ductal carcinoma in situ

Fig. 1

The graph shows a slight increase in oestrogen receptor (ER) positivity rate over the time accompanied by a quite similar change in breast-conserving surgery (BCS) rates. There was a steady increase in screen-detected DCIS and radiotherapy rates over time. There were slightly lower rates of high-grade DCIS from the start of the study till the end, which were reflected on HER2 positivity rate. Low-risk DCIS rate increased over time as well. *Radiotherapy rate for BCS-treated patients only, **DCIS risk estimated based on tumour size, grade and age at diagnosis.
