Tangle had accute myleophistic leaukemia in 1997. Fortunately he was young enough to have survived it even without a transplant.
Of course not doing anything and "hoping it will go away" will not work. I suggest you by a copy of Andrew Weil's 8 Weeks To Optimal Health. He begins the book with a case example of a young lady with a similar condition to your father's, axcept worse. She had a remarkable recovery, so did Tangle.
If you will flood his body with theraputic amounts of nutrients, plus medicinal herbs, he should show immediate if not complete recovery in a matter of weeks.
