Hi, I'm a 19 year-old male and a few weeks ago I noticed a lump under my right arm, just below the armpit. It's approximately pea sized, similar to or smaller than a baked bean, and is a regular oval-ish shape. It feels hard and swollen, but not extremely. Originally there wasn't any pain (or at least I didn't notice any), and whilst it's still not painful to touch, I'm occasionally noticing a feeling of tenderness in the area, though it's not constant. I'd say the lump is movable, but it's a bit difficult to tell- it seems to move from side to side under slight pressure. As far as I can tell I don't have any other symptoms.
I personally don't have any previous medical history that I can think of to explain it, but my maternal grandmother had a mastectomy (although, unlike me and my parents, she was a heavy smoker early in life), and my mother's cousin died very recently in her fifties after suffering from cancer. Although I don't know what kind of cancer it was, I've become very worried about it and if there might be a connection.
I know swollen underarm lymph nodes are a common symptom of lymphoma, but I also know that they swell up for a lot of less serious reasons. I have a long-standing anxiety about going to see doctors/hospitals, but I'm worried that if I have something serious it could be getting worse. I don't know whether, in my case, the stress of getting a consultation, potential scans etc. would be worth putting my mind at ease.
