Hi, I'm 21 and have been having a reoccuring lump in my armpit for over a year now. I had surgery to remove it in April because it was the size of a golf ball and painful. It started coming back in a different lymph node this time but still in the armpit. It is about the size of a cherry now and tender but not too painful. I saw a Dr. yesterday who said it is probably a cyst and I'm seeing a surgeon tomorrow who will likely biopsy it. After doing research online yesterday and today I'm reading that this is sometimes a symptom of lymphoma , has anyone had this same symptom? what was the outcome? thank you!
