JACKSONVILLE, Fla. -

A 45-ton machine designed to kill cancer cells completed its four-day journey from Boston to Jacksonville.

The towering apparatus called a "cyclotron" arrived in Mandarin Saturday morning. It will generate protons used to treat cancer patients at First Coast Oncology.

The machine can target cancerous tumors with unprecedented accuracy, without hurting healthy tissue or organs.

Scott Ackerman, M.D., with First Coast Oncology, said Jacksonville is just one of four cities to get the technology.

"This project, all told, costs over $30 million," Ackerman said. "I'm very excited that we are able to bring this lifesaving technology into our community."
