My dad was diagnosed with stage IV gall bladder cancer. He is carrying a large size tumor that has evaded the liver, small intestine and possibly other organs. We were told with surgery they would be able to remove the tumor and things would be fine. But it turns out they discovered during surgery the tumor evaded the portal and arteries that carry blood flow to the liver. If only one of these were infected then they could have successfully removed the tumor including the gall bladder and part of the small intestine. The surgeons were shocked to see that my father was carrying this huge tumor around without any pain or discomfort. They told us my father was a strong healthy person. He just turned 74. After the unsuccessful surgery he weirdly regained his appetite he has color on his face and walks fairly ok not as well as he use too. He did loose about 25lbs two months prior to the surgery due to lose of appetite. Hes scheduled to see an oncologist next month. My family and I are so sad. Hes such sweet loving wonderful man.
