CHARLOTTE, N.C. (CBS) -- A stranger gave Patricia Curry the lift she needed, in more ways than one. The 58-year-old was on her way to treatment for stage 3 breast cancer.

"When you're going through this, you need to try and think positive," she said. "I've cried many days just thanking God, you know, because they was right on time, you know."

She's talking about ChemoCars, a service in metro Charlotte offering free rides to cancer patients getting treatment. It's Zach Bolster's brainchild and passion.

"Cancer can be scary and feel uncontrollable," Bolster said. "We want to take this one piece of the process, transportation, and make it simple so they can focus on what matters most, getting better."

Bolster's mother, Gloria, had stage 4 pancreatic cancer. He quit his job on Wall Street and moved to Charlotte to drive her to doctors appointments and chemo sessions. Bolster noticed that many patients, often older and lower-income, missed treatments because they had no reliable ride.

"It was heartbreaking and unfair to see that some people didn't have the exact same shot at beating cancer as others," Bolster said.
