Now, after all that has come out, the tattoo embarrasses him and he is torn over what to do.

"I still support the Livestrong cause and I am still in awe of what Lance Armstrong was able to do, doping or not, but both the foundation and Lance are now tainted," he said in a CNN iReport.

"It is incredible that he won seven Tours, but he cheated. It's plain and simple. And the fact that after all the cancer he suffered from he would do unnatural things that could harm his body is just something I can't fathom."

Before he got his tattoo, Schuster started wearing the yellow bracelet in 2004 in an effort to scare himself out of smoking. Then, his father received an abrupt diagnosis of stomach cancer in 2005. Schuster gave him his bracelet when he went into the hospital for surgery related to his stomach cancer. He never left.

The day his father died in 2005, Schuster held his hand and slipped the yellow Livestrong bracelet off his wrist and onto his. When the bracelet wore out a year later, he got it tattooed onto his wrist. The tattoo artist didn't think yellow would wear well and made it red instead, Schuster said, so people don't immediately recognize it.

He has no plans to get rid of it, given all that it means to him. As for his father, he had a dry sense of humor, he said.

"I would like to think he's chuckling somewhere and smiling about the whole situation."
