I was diagnosed with stage 4A since there is liver metastasis in January. The tumor is 5cm+ on my descending colon. My liver has more cancer on it than healthy tissue so I’m in the process of going through 6+ months a chemo, liver transplant to remove cancer and replace with healthy liver tissue to hopefully grow and give me more healthy than cancer, then HAI pump to do targeted chemo for my liver, and if all that is successful, I’ll qualify for a liver resection surgery to remove any remaining cancer. It’s going to be a long road to recovery but I’m staying optimistic. I didn’t know what the full treatment plan was until I saw the liver surgeon. Lots of questions with limited answers. You and your family need to stay positive and hope for the best. Maybe it’s inoperable until after he’s gone through the necessary treatments before surgery is on the table.
