What do you mean by cluster in arm pit, the mammogram showing three lumps in the left breast and a cluster and was advised for a Biopsy?
Patient: My daughter had a mammogram and they found  3 lumps on left breast and a cluster under her armpit. She is 35, went on birth control approx 6 months ago. They are going to do a biopsy on the cluster. She also has a tendency to get kidney stones. I'm worried about the cluster. Can you give me a better explanation of what a cluster is Doctor: Hi, I have read your query and according to my opinion these cluster are enlargement of lymphnode ,that's occurs due to any type of infection in there draining area.That infection may be bacterial or malignant.Thanks for using HCM.
