Somewhere he said he was cancer free....
No such thing as cancer free. Reason cancer occurs is because body has lost ability to recognize cancer cells as non-normal. Surgery, radiation, chemo can stop cancer temporarily. Given enough time, cancer will always come back.
The real bad part is all cancer treatments also kill normal cells and weakens the body. Therefore enjoy everyday we are blessed with health. We are all here temporarily. Even Soros will die regardless of how much wealth he has.
