Association of Breast Conservation Surgery for Cancer With 90-Day Reoperation Rates in New York State

Use of BCS has decreased overall, most steeply in younger women. Nearly 1 in 4 women underwent a reoperation within 90 days of BCS across New York State from 2011 to 2013, compared with 2 in 5 from 2003 to 2004. Rates vary significantly by surgeon, and initial BCS performed by high-volume surgeons was associated with a 33% lower risk for a reoperation.
