WHITE PLAINS - An 85-year-old building at White Plains Hospital is set to disappear.

Its demolition marks the start of a major expansion that will double the size of the hospital's Cancer Treatment Center.

"To have to trek to New York City or other places is a lot," said White Plains Mayor Thomas Roach, who completed cancer treatment at the hospital five years ago. "It's a great investment."

Along with the expansion of the cancer treatment center, the other side of the hospital is getting a $100 million transformation of its own.
