Patients with large breasts may have back pain. Back pain can be caused by many different things. Back pain may improve with a breast reduction. Intuitively it makes sense, because surgery will reduce the overall weight of the breasts, thus putting less stress on the back. There are numerous studies in the literature that support this concept. I do tell patients that back pain can occur for many different reasons and that symptoms may not improve after breast reduction. Fortunately, many patients do have improvement of back pain after undergoing a breast reduction.
