Anecdotal, but my cousin was stage 4 skin and throat cancer (2 separate origin cancers), tumor ridden, on the way out. His doctor somehow got him in on a clincial trial (immunotherapy) at the Dana Farber cancer institute in Boston, MA.<p>That point-blank saved his life. The cancer was gone within 4 months; he&#x27;s been cancer free for 5 years. His younger brother was not so lucky, lung cancer (heavy smoker), he didn&#x27;t last long after diagnosis.<p>Anyway, the OP isn&#x27;t looking for miracles, he&#x27;s preparing for his departure, in a beautiful and dignified manner -- totally respect the choice, but longshots are not the same odds they used to be wrt to cancer treatments, even stage 4.
