Abstract
The rate of surgical site infection (SSI) after breast surgery is higher than expected for a 'clean procedure'. There is currently no consensus on the use of antibiotics, and as a result there is variation in use. An infection may compromise cosmesis and delay the start of adjuvant therapy. This research highlight reviews a recent paper by Gulluoglu and colleagues investigating the use of antibiotics in overweight and obese patients undergoing breast cancer surgery and also reviews the current literature on this important topic.
