Swollen breast on opposite side of breast cancer

DabbaDeb1956

I had breast cancer 30 years ago (right breast). I had lumpectomy, axillary dissection(lymph node removal), chemo, and radiation. My right breast and arm have always been slightly larger than the left since the treatments. I battle cellulitis and lymphedema in the right arm too. I frequently use care specialists for manual lymphatic drainage sessions and wraps in the right arm when the swelling is severe. I wear a compression sleeve.

Here's my problem: now my left breast is very swollen. (My right side is under control). I've had a mammogram and it showed nothing. My care specialists are trying lymphatic draining massages on the left side, but the breast swelling is not going down.

Any help or suggestions would be appreciated. I've got a compression bra being ordered for me
