Please help my father Rustico with his medical needs. He was diagnosed with Colon Cancer Stage 2 going to stage 3 and liver cirrhosis... He is now having complication with his liver causing his tummy to swell. The doctors said, that he might need to undergo liver transplant but it is too expensive. He needs to undergo operation as soon as possible and some additional treatments like chemo and medication. He is fighting and is very willing to live,..But we don't have enough money.. Please help us.. Please give him a chance to live longer... Any amount would be very much appreciated. Thank you so much in advance.
