Dear lactnetters, A friend who has asked me to help her with a client she is seeing. The mother had to have a mastectomy a few years ago. She is pregnant and will be having a repeat CS in 2 weeks. A lump has been found on the side that had a mastectomy. Her Dr. will be giving her radiation therapy, starting 2 weeks after delivery. Understandably this is a very sad story but the mother would like to try and nurse at least for a while on the unaffected side. Our question is: will lactating on the one side affect the remaining tissue and cause any problems with the radiation therapy? If she is nursing on the unaffected side is there any chance she could nurse during or after the therapy. If she pumped during the time she recieves therapy could she go back to nursing? Say some prayers for this poor woman.:( Linda Rosetti RN, IBCLC CLarkston, Wa.
