The doctor took one look at it, and said it was (several multi-syllable words I’d never be able to recall). When I looked blank, he said it was a pre-cancerous growth. Easy to fix, he said, by freezing it. Whereupon he picked up a container and proceded to spray the spot with what I believe was liquid nitrogen. YOUCH! “Well, I didn’t say it would be painless, did I,” said he. It wasn’t that bad, but it sure took me by surprise.
“Come back in a month to be sure it’s come off,” he said as he dismissed me. The whole thing must have taken all of 10 minutes.
