Hello. I am a 25 year old female. I am 5'4 and weigh approximately 120 pounds. In February I noticed a small bump in my left underarm right by my breast. The area was sore and when I touched the bump it would move around without a problem. I went to a gynecologist as I thought it was a breast lump and he sent me for a sonogram. The sonogram results are attached. Generally, they found the bump to be a lymph node less than 1 cm and benign in appearance. They told me it was nothing to worry about. Not being completely happy with that answer, I went and saw a hematologist. He felt the lymph node and read the sonogram report. He indicate he thought there was less than a 0.1% chance it was anything to worry about as cancer does not usually hurt and because of my age. I made a follow up appointment a month later and when I went the second time he send me for a follow up sonogram to see if the node as grown. The sonogram had the same results, except the node has actually gotten smaller. I never went back to the doctor. It has been about two months since my follow up sonogram and I started getting pain in that arm pit again. I can still feel the node but it is not as big. Today I found a small bump on the right side of my crotch which feels the same as the node in my underarm. It does not hurt and it moves around easily. It feels small. This is causing me some concern. My question is based on the sonogram results and my symptoms should I go for what would be a third opinion on the node in my underarm and have the one in my groin checked out? The doctor indicated that sometimes lymph nodes can be felt easily on thin people so that may be why I can feel some. I have no other symptoms. Thank you for your help.
