question: My father has a grapefruit size lump in his armpit. He has had an MRI recently and they are going to remove it. He is scheduled for surgery in two weeks. They are taking it out to check to see if it is cancerous. He had prostate cancer 3 yrs. ago (had prostate removed)- counts /margin came back good then.  His Dr. is saying that he may have nerve damage due to the size of the armpit lump...is thim common?
