DENVER -- The battle against cancer is still an uphill battle, but doctors at the University of Colorado Cancer Center believe it's making progress.

"Cancer is increasingly a curable or manageable disease," said Dr. Tim Byers at UCCC.

That means more and more cancer survivors are living longer. UCCC started a trial focusing on helping breast cancer survivors live healthier lifestyles after treatment. Rehabilitation, Exercise, Guided Assistance, and Information or REGAIN are the four areas UCCC hopes will help patients after cancer.

Kate Layhe is a breast cancer survivor. She's going through the study.

"I found a lump in 2005 just before I was going to have my mammogram," said Layhe.

Doctors at UCCC put about 100 breast cancer survivors like Layhe on the REGAIN program. They wanted to see if physical activity combined with healthier living helped survivors.

"Now our challenge is how can we make breast cancer survivors healthier? Maybe even healthier than they were before they had breast cancer in many cases," said Dr. Byers.

For Layhe, the program has helped her get back to doing all the things she loved before being diagnosed with cancer, she said.

"If any of us were to feel a little bit depressed or sorry for ourselves, when you start exercise, you completely forget about that for a while," said Layhe.
