Hi, Thanks for writing in. There are channels in liver through which bile passes Goatskin tumor or Hilary cholangiocarcinoma is a cancer at the point where the biliary channels from right and left lobe of liver meet. This is a difficult condition and staging is required to discuss the treatment options and curability. Free fluid is the fluid that is collected due to many causes like inflammation and cancer. The fluid collection amount can vary but usually collection of fluid in a cancer patient means that the disease is progressing. The prognosis of goatskin tumor is good in early stage but when detected at later stages chemotherapy is best to extend survival. He should be under complete treatment at a cancer center for chemotherapy as required and given medicine to reduce pain. Please do not worry.
