My Uncle Is 48 Years Of Age And Has Just

My uncle is 48 years of age and has just received news that he has been diagnosed esophageal-cancer. He has taken tests to find out if it has spread at all. His stomach, lungs and everything is clear except his lymph nodes have it too. The doctor gave his a 45% chance. They are removing his esophagus and going to try to stretch his stomach to replace it. He starts chemo in a week and has surgery in 2 wherw they said he will have to stay in hospital for aboht 2 weeks then have a 3 month recovery. Can you please help provide me with all the info you can about this? Does being found in the lymph nodes make it Matastatic-esophageal cancer? Meaning it can't be cured? Can he beat this? Is there more we can do? Light therapy? Himalayan salts? Vitamin b17? THC oils? I need all the help I can get.. please help me
