question: My father who is diabetic hypertensive and IHD with stent placement done in MAy 2012. now doctor while taking ultrasound is suspecting Gall bladder cancer , so MRI was taken. Doctor told its stage IV with liver and periportal lymph nodes ivolvement . Doctor suggested palliative open colecystectomy? Father is right now very fine doing his normal duties, no symptoms. I went to take second opinion from another doctor. He ask for CT scan saying MRI is little doubtfu. it might be chronic inflammmation too. Now is a CT scan actually required? Other people are telling not to subject him to surgery as it will only torture him. Please advice????
