Giants co-owner John Mara is battling cancer.

In a statement shared Monday by the team, Mara revealed he has “recently been diagnosed with cancer” and is “feeling strong and optimistic” while “following the treatment plan recommended by an outstanding team of doctors.”

“I’m committed to seeing this through to a positive outcome,” Mara said. “I plan to remain active with the team throughout my treatment, and I’m fortunate to be surrounded by incredible support — personally, professionally and medically.”

The Mara family has requested privacy at this time.

The statement comes one day after the Giants recorded their first win of the season, a 21-18 victory over the Chargers at MetLife.
