Pain following mastectomy surgery for breast cancer can be significant. Poorly managed pain
in the immediate time-period following surgery can potentially lead to long-term (chronic)
pain conditions. There is still a need to find the safest, least invasive, and most effective
method to manage this pain. The investigators believe that a new technique of injecting local
anesthesia (freezing) in to specific areas at the end of mastectomy surgery may be a very
important step to managing pain after breast surgery. The investigators would like to begin
by performing a pilot study, meaning the investigators will perform the technique in patients
and compare what their pain outcomes are to patients who have not had the technique.
