On his show he says a speedy MRI was done on it and the docs are concerned. It’s not a lipoma nor a cyst, apparently.
Pray that it is benign, because it appears to be a tumor, at least from what was said on the show.
My friends cousin had a growth behind his ear a few yrs back, the 1st doc said it was nothing, then it kept growing and it turned out to be non hodgkins lymphoma, he needed 6 rounds of chemo but thank God it has not returned, very high cure rate..not sure how old Dan is just praying he will be alright
