Reoperation rates higher with breast conservation

A study of 55,000 women with breast cancer in England over a three-year period found that the rate of reoperation almost doubled when the tumour had a carcinoma in-situ component.

More than half (58%) of breast cancer patients in England choose breast-conserving surgery, which, when combined with radiotherapy, produces similar survival rates to those achieved with mastectomy alone, the report states.

However, the study found reoperation was more likely among women with carcinoma in-situ disease (29.5%) compared to those with isolated invasive disease (18%). Around 40% of women who had a reoperation underwent a mastectomy
