What causes pea size lump under right arm?
Patient: I discovered a pea size knot under my right arm, when I press on it, it feels as if the mass may be the size of a grape. I have had cancer twice. At the beginning of this year tests have been very good and the doctors said they need not see me for one year. I am frightened. Doctor: Hi,It seems that there might be having enlarged axillary lymph nodes giving rise knot and and lump.As there is h/o cancer, keep watch on it and if size increased or becomes painful, get it removed and go for biopsy.Ok and take care.
