question: hello my mother had gallbladder surgery because her gallbladder quite working. they removed it and they sent it for path study it came back positve for cancer of gallbladder the Doctor felt it did not go through the lining of the gallbladder. He said they would do routine blood work If liver functions go up they would do a Ct Scan. Her liver was elevated once and then they did CT Scan It showed swollen lymph nodes throughout her stomach but she feels great no symtons went oncologist and he did a CA19-9 the reading was 7 no cancer is this test reliable? The Doctor states that the reason why liver function was elevated because the lymph nodes in the area where the gallbladder was removed was pushing against the bile duct, her labs are good now. Does she have cancer or not?
