A father with leukemia, a daughter who gave him a second chance at life, and a grandson who is a hero in the making. This is the extraordinary story of the love between the three.

Jadyn Jensen is ten years old, typical in a lot of ways. He likes teasing the fish in his grandfather's tank. He's proud of the model car he and his Pop Pop put together.

Once, the two of them shaved their heads to raise money to fight cancer.

"First we were just doing it for fun," Jadyn says.

Two weeks later, he found out Pop Pop had cancer.

"I was just widely surprised,” the ten-year-old says. “It was like predicting the future I guess."

It was three years ago. It was the start of a very unusual story.

"He had everyone there and told me I had leukemia," says Jim Jensen, Jadyn’s grandfather.

For two years, Jim fought his cancer. He says while the chemo did cause him to lose his hair, it never made him sick. But, it also didn't make him better. Doctors gave him seven weeks to live.

"They said he wouldn't be here for Christmas," says Kerry Jensen-Wright, Jim's daughter and Jadyn 's mom.

But, there was hope: An experimental bone marrow transplant at the University of Minnesota Medical Center. Jim’s daughter, Jadyn’s mother, would be the donor.

Doctors first did a blood transfusion, taking the killer cells from her blood and putting them in her father's blood stream to fight the cancer.

"After a period of time, they said 100 percent of Kerry’s killer cells were working," Jim tells us.

Then came the marrow transplant; followed by more good news.

"As of now, the leukemia is gone," Jim says.

That makes Jim the first person in the world to beat leukemia after the particular treatment. That still brings tears to his daughter's eyes.

"It's not rewarding, but it makes you feel good," Kerry says, wiping those tears away.

"What can I say? If it wasn't for her, I wouldn't be here," Jim says struggling for the words.

Jim had to stay near the hospital in Minneapolis until just a couple weeks ago he got to come home to Eau Claire and home to his grandson who kept himself pretty busy during Pop Pop's illness. Jadyn continued the tradition he started with his grandfather. Every year, the Eleva forth grader raises money for the St. Baldrick's Foundation. This year he's collected $400. Last year, he raised $900.

"He's just been there. Just been there. They say there's always a reason something happens and there he is," Jim says smiling over at his grandson.

So while some of the lifesaving efforts of this endeavor go right over his soon-to-be shaved head…

"I prefer bald. I don't have to comb my hair that much," Jadyn says, eyes twinkling.

… Jadyn Jensen is a little kid, doing a big thing, without even realizing it.

Jadyn has a big day coming up in March. The Minnesota Timberwolves are going to honor him as a "Hero in the Making" Jadyn and mom and Pop Pop, his principal and a bunch of friends will all be at the game. Jadyn says he's most excited to be court-side for warm-ups, get an autographed basketball, and of course, the best part, he gets to leave school a little early for the big game.

Jadyn 's head will be shaved this year on March 14 at the annual St. Baldrick's fundraiser in Eau Claire.
