hi, i am a 30 yr old male, fit, healthy, not overweight, eat well, non smoker etc. have quite a good size lump under my right armpit, non painful, not soft nor very hard, gland like texture. had smaller lumps checked last year at docs, blood tests etc all came back fine. not sure now if this large lump is new or an existing one that has grown. have history of lumps, had Gynecomastia as a teenager. generally feel well, no weight loss or fever etc just a bit concerned by the size of the lump and what it may be. any advice bar the obvious go see my GP would be appreciated. thanks
