I have found an oval shaped lump in my armpit and it is quite big. I have not noticed it before so I was really panicked when I saw it. I went to the GP today and she said to wait six weeks which I really can't see myself doing. She then said she didn't know what it was! Has anyone had something similar to this as I wondered if it was a lymph node enlarged. I am even considering going privately for a biopsy as I can't wait six weeks.
