Good news for me. NO CANCER!!! My knee cap had broken off at the end and thats what they saw in the X-Ray. Both side of my knees had torn cartlidge and had bad artritis which they scrapped. Hell of alot of pain and all I can take is Tylenol. They left the broken part of my knee cap in as it's not causing much pain(HaHa) Thought you all like to know
