I am concerned about my son's swollen axillary lymph node. It is 1cm in size, movable, soft but has been there for 2 1/2 months. The doctor has said there is no need for biopsy, as it is small ,not getting bigger and there are no other prominent nodes. His CBC shows a normal WBC profile but his RBC is microcytic, hypo chromic. His eosinophils are about 10 times normal . He has been given worm medicine and has been on a course of iron therapy for 2 months but the follow up blood work still shows no change. Should the lymph node be biopsied?
