I am exactly one year out from my WLE on my central to upper back, and SNB from my left armpit. Today at Physical Therapy for pain in my left shoulder my therapist found a large lump in my armpit. I’m doing my best staying calm and collected tonight but I’m not going to lie, my head is spinning a bit. I’ll be calling my dr and possibly the surgical oncologist tomorrow morning, but I am curious if anyone else here has found a lump a year after the SNB near the site of lymph node removal. Thanks!
