You will have a short scar in the shape of a line where the biopsy sample was taken. Usually breast lumps are not large enough for them to cause a change in your breast shape when they are removed. Most women have some soreness in their breast and some swelling near the surgery site for a few days.
Some patients experience some nausea from medicines used for anesthesia or anxiety.
These complications are mostly heart and lung problems and infections. For breast surgery, the risk of complications from anesthesia are smaller than average, because you will not be receiving anesthesia for very long and because the surgery is only slightly more than skin-deep.
