It turned out that the procedure to have my tumor removed would result in a black, swollen eye for 3-4 days. And it might hurt afterwards.
So I postponed the surgery. Next available date was this morning, December 12th.
It sounds a little nuts, but I'm sitting here with stitches under my right eye and a little 'shiner', thinking I wouldn't have enjoyed the concert if I was self-conscious and uncomfortable. I'm not hurting at all, but if things hadn't gone right, that Monday and Tuesday in October would have been spoiled. The tumor wasn't going anywhere, so it wasn't an emergency. I was actually told by the dermatologist that I could wait a few months if I needed to.
So, my question for the peanut gallery: Have you postponed anything mildly important for U2?
