Found lump in left arm pit, same side I had lumpectomy done on April 27th, terrified.

I'll be watching for your update! I, too, found a lump directly behind my axillary scar, but it turned out to be a seroma. As my provider said, 'nature abhors a vacuum', thus the seroma developed. Prayers for a good report.

Great news! I learned not to Google my symptoms 😖

I have a big knot under my surgical arm also. I had it checked and they did an ultrasound and it's just a pocket of fluid. In fact. it's about gone. Massage it a little every day and it will be fine. Also I had been doing some kind of heavy lifting cleaning out my storage building, and I thought that might have caused it, but it may have no relation. I don't think you need to be scared. Just have your doctor check it out! Prayers! You probably know by now, I'd like to know what they said.
