Do you administer prophylactic antibiotics during a partial breast balloon brachytherapy treatment course?

We do use prophylactic antibiotics to reduce the risk of infection. One multi-institution study with Mammosite (Cuttino et al in the Red Journal) suggested a reduced infection rate with the use of antibiotics.

Our infection rate is extremely low, with only one case in the past two years, so we also do not use prophylactic antibiotics.
