Giants owner John Mara announces cancer diagnosis

New York Giants co-owner John Mara announced his cancer diagnosis on Monday.

The 70-year-old team president and chief executive officer said he is feeling "strong and optimistic."

"I have recently been diagnosed with cancer and have been following the treatment plan recommended by an outstanding team of doctors. I'm feeling strong and optimistic, and I'm committed to seeing this through to a positive outcome," he said in a statement released by the team.

"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. I ask that you respect my privacy and my family's privacy at this time."

Mara did not provide any specific details about his diagnosis.

His revelation came one day after the Giants earned their first win of the season, defeating the previously unbeaten Los Angeles Chargers 21-18 at home behind rookie quarterback Jaxson Dart.

Mara has been the president of the Giants since the death of his father, Wellington Mara, in 2005. John Mara's grandfather, Tim Mara, founded the franchise in 1925.

The Giants have won two Super Bowl championships (XLII, XLVI) during John Mara's tenure.

Mara and his wife, Denise, have one son and four daughters.
