TULSA, Oklahoma - A Tulsa tattoo parlor is tattooing for 24 hours straight, all in the name of cancer research.

It's called the 24-Hour Tattoo Marathon, it's an annual event sponsored by Spaded and Jaded, a Tulsa tattoo parlor.

Tattoo artists have come to Tulsa from around the nation to be a part of the event; they say it's worth every mile.

"My son has brain cancer and we do everything we can to give back to that community that we are unfortunately having to take from," artist Kenneth Macpherson said.

The marathon started at noon Friday and ends Saturday at the same time.
