A few question. Why cant measurements be in inches wich is American system. Its very confusion. Also I find it interesting that surgeons referto scans after lymph node biopsy. If you cant see it befor the biopsy why after? Also SURGEONS NEED TO BE UP FRONT ABOUT THE PAIN INVOLVED LYMPH NODY BYOPSY. IT NEEDS TO BE DONE UNDER SEDATION...ITS EXTREMLY PAINFUL.
