He's going for testing on 7/22. There's a 'spot' on his pancreas that they can't reach by a needle biopsy. He's on medication, which I can't spell: something like 'Kumoden', and he must be off that for 5 days before they can run the test.
They are trying to see just what exactly IS the situation, but he's not a happy camper.
Please keep him and his wife in your prayers.
