So from all the info I have seen, he has a type of skin cancer that spread to a lymph node...I had never heard of lymph node cancer so I assumed it was lymphoma, which is far worse than what he has, Squamos Cell Carcinoma.
Sounds like they caught this early and it should not be as demanding as I thought when I first saw the news. If it is in the early stages, as they say, this is very treatable.
If he is as tough as my 76 year old mother battling stage 4 neck cancer, then he will be just fine.
