Ultrasound would determine if the lumps are tumors (mass) or cysts (liquid). If they're cysts, you'll be fine and they will be removed only if they are causing some discomfort. If they are mass, BIOPSY IS NECESSARY to determine if they are malign or benign. If benign, they will be probably removed. If malign, meaning cancer, earlier you know, earlier the treatment can start and be successful!!!
