Lumpectomy: exercise, OT etc.. before surgery ?

With hindsight, I would have spoken to a good lymphoedema therapist before surgery (as I knew I had a number of suspicious looking lymph nodes which would be removed - all but one were benign) about minimising risk. I did all the recommended exercises religiously, but didn’t notice anything until I realised my watch band was too tight! It may be worthwhile to be prepared! I do have lymphoedema but with a good therapist, it’s quite manageable. Best wishes.
