Small Hard Lump in Armpit

Hello everyone. I had a lumpectomy in July 2016, nodes were clear. I’ve just found a small hard lump in my armpit behind the scar from the lymph node removal. I had an ultrasound just three weeks ago which was clear. I found this new lump last night. Feel very worried and wondered if anyone had had any similar experiences - hopefully with a positive outcome. x

Hi buster I found a ump in my remaining breast a year after chemo had finished it turned out to be a cyst hope you get peace of mind soon ?
