Dear krolik: Lymphedema is a relatively uncommon condition that can occur as a result of lymph node damage or removal (which often is done with a mastectomy). Lymphedema used to be more common when the numbers of lymph nodes that were removed were in the 20's and 30's, rather than the 6-12 range that they usually are today. While we cannot evaluate whether there is evidence of lymphedema without seeing you, it may be important to note that our hands are rarely the same size. Usually one is larger than the other. You might benefit from your surgeon or an oncologist to evaluate whether the hand is swollen from the procedure or whether it is really lymphedema. If the concern is lymphedema, occupational therapists who specialize in lymphedema can make good recommendations in terms of what interventions (including compression sleeves) may be helpful.
