I am not a physician. But my experience is that there are differing opinions on resection. It can depend on co-morbidities and overall health of the patient.
I was stage IV and did have liver resection. I am now having a “blip on the radar” which may require chemo or lap surgery to get one more out.
I would definitely get a second opinion from surgeon who does this regularly. They can be found by a call to PANCAN
