Well this was a roller coaster.
I apparently had a successful visit, because my brother agreed to have the surgery. I think he realized the choice might be taken from him, but he sensed resigned to it, which is about the most optimistic most people would be in his situation.
During the surgery, though, they found that his colon issues were limited to a relatively small portion of the organ, and while it's not the textbook approach, the surgical team decided to remove the damage and repair it instead of going with the colostomy bag. Which is risky, but considering the risk of him taking care of himself long term, it's good news. And he was in a much better mood today.
And now it turns out that they got results from the lab. It was cancerous. They don't know much yet, and he's not ready for any more surgery or other treatment yet so we're in a wait and see mode.
I should have known. This kid can't catch a break. It's one of the more treatable kinds of cancer, but still a huge swing.
So now I'm going to have to schedule a colonoscopy for myself. And a reminder to all of you to get your butts checked too.
