Breast swelling is not something we have seen after tummy tuck over many years of practice. Some would wish breast swelling to be so, yet we don't have any explanation as to a relationship between the two. Best of luck, peterejohnsonmd
Although a tummy tuck would not cause breast swelling, it is possible you are experiencing overall body swelling from fluid retention that makes your breasts appear larger. You may also be noticing a greater difference between your breast and your tummy. Checking your weight will help to differentiate this.
