I recently visited my doctor and showed him a darkening under a toenail. He looked at it and decided it was just some blood, but he hid tell me that cancer developing under a toenail, while not common, does happen.
Further, he said that it is extemely rare among caucasions.
Someone should alert Jesse and Al about this racist form of cancer!
Do you go around barefoot in the sun alot? I know lots of folks who summers on the beach and boats barefoot - I guess it can happen.
