Hi, Thanks for writing in. A cancer of gall bladder possibly infiltrating the liver is a difficult situation. The liver contains small channels through which bile passes and then when the cancer starts infiltrating the area, the bile channels get blocked. This leads to impaired biliary drainage and exactly what has happened with your cousin. As far treatment is concerned, surgery has been done but there was infection in the area for which they have given medication. Regarding diet and food, it is best to give healthy food cooked at home. The food must cause the least stress on the liver. A low oil and non spicy diet is suggested. You can give lots of fruits and boiled vegetables. Proteins are to be given as per liver function.
