Neuroendocrine tumor. Helpful for us.

Hello, Recently 2 years back my father has gone through the right hemicolectomy surgery due to neuroendocrine tumor. Now he been going through the radionulcide therapy in Tata.But recently he is getting stomach problem like obstructions and we have done whole body Cect scan. R And report shows the following impressions: Small polypoidal lesion seen involving the small bowel probably distal ileum. Large heterogeneous SOL with solid and cystic area seen involving the right lobe of the liver with segments vll and vlll. Cholelithiasis noticed. Also we have done FNAC test in that it's shows no malignant cancer cells. We need the detail explanation on this and also what steps we should take for the better treatment.
