If your father does not have insurance, get him Medicaid. There are other programs available to get help but they may take a while and your father probably does not have very long unless treated. Removing the glalbladder is an option, but if it is stage 4, then it has already metasicized soemwhere else -probably the liver. He needs treatment. CAll medicaid tomorrow and keep calling doctors until someone agrees to help. They are out there!
