The "C" word is so scary but keep in mind - it doesn't mean a death sentence anymore. They are make great strides in cancer treatment and research. Your Dad will pull through this, I'm sure of it.

Keep a strong and good attitude and repeat after me "It's only a bump in the road." Puck is right - there's no point in spending energy worrying about that which you have no control over. Instead try to find some humour - I don't mean that in an insulting way. Cancer is nothing to laugh at, I know, but keeping a good attitude and sense of humour is the key to recovery.

Prayers on the way from me.
