Prayer request

I doubt anyone reads this anymore, but I have to post this. My dad is going to have surgery soon, but I don't have the date yet. He has a tumor in his bladder, and it's cancerous. The doctors don't seem to be worried about it, but it scares me some anyway. It's not yet three years since cancer killed mom, and I'm definitely not ready for dad to go.
If anyone's reading anymore, please pray for my dad. Thanks.
