Oh I'm so sorry! 
Hopefully, it will turn out to be something else.
I don't know about dogs, but I do know horses, believe it or not, get skin cancer. White horses esp. and the fellows with pink on their noses --- people put sunscreen on them, if you can imagine!
Apparently, though, sunscreen works for horses, so just don't see why it can't work for dogs. ? I'd guess the trick would be finding one which wouldn't muck them up. If it's just the belly area, it wouldn't be so bad because not so much fur.
In any case, good luck!
