Wife went to dr b/c we noticed large bump (size of baseball but more oval) on back. The dr looked & said it resembled a lipoma. He sent her for an ultrasound. The dr called back & due to size & growth, they would like her to have an FNA biopsy.We have a consult with surgeon Thurs. I have read that FNA's aren’t the best type of biopsy for diagnosis b/c they contain only cells & don’t provide any info about the overall tissue architecture. Can we, or should we, ask for a Core Needle biopsy instead?
