I grew up in California and my sister and I spent days in the pool, never with any sunscreen because we were the brown-as-a-berry type girls. Also, it was the 1970s. In my adulthood, I have reaped the rewards of this lifestyle in the form of the occasional spot of skin cancer. It's the basal cell type; inconvenient and unattractive but not really dangerous.
This summer, I had a spot scraped off my nose. The resulting pathology showed that the margins were still funky. This spot would require a Mohs procedure, which is as much fun as it sounds. I underwent that procedure on Tuesday of this week. An 8 mm chunk on the surface of my nose is gone (as is the skin cancer).
