[|Human|] My husband has colon cancer spread to the liver. The tumor is in the sigmoid colon . A stent was put in to try to help his obstructed bowel but it didnt work. A loop colostomy was performed & appeared successful but he has swelling in his scrotum & legs. They are taking steps to relieve him of this, but we are concerned that he may be in liver failure & they arent telling us. He has had 4 bouts of chemo & his ct scan showed good results on the liver. Thanks for your input
[|AI|]  Good evening. I appreciate your worry for your husband. There can be multiple reason for swelling like low blood albumin level, venous thrombosis in blood vessels of lower limbs or some tumor node pressing on the blood vessels. He does not seem to be in liver failure as he is tolerating chemo well. You can discuss these possibilities as I have mentioned with your doctor, and he can advise more test accordingly. Regards
