The 46-year-old Lavin said in a statement Friday he was diagnosed in September and was told he could delay treatment until after the season. He will begin treatment in the coming weeks. The statement did not say how he will treated.
"My family feels fortunate that through annual health exams, we detected my condition at an early stage," Lavin said. "This past fall I didn't want to distract our team, but with the season behind us, we are now working with medical experts and taking the proper steps to tackle this health challenge head on."
Lavin's urologist, Jonathan Schiff, described Lavin's condition as a "relatively low-grade cancer."
Lavin inherited a roster with 10 seniors. After a rough start, St. John's won eight of nine with four of the wins over ranked teams. The Red Storm lost three of five to end the season.
Lavin was hired at St. John's in April after seven years as an ESPN analyst. He coached at UCLA from 1996 to 2003 and was fired after leading the Bruins to a 145-78 record that included six NCAA tournament berths.
The Detroit Pistons announced that billionaire California investor Tom Gores has agreed to buy the struggling NBA franchise, ending a drawn-out sale by longtime owner Karen Davidson that stretched back before the season.
The tentative deal, which also includes the Palace of Auburn Hills and DTE Energy Music Theatre, must be approved by the NBA. Terms were not disclosed, but the deal is expected to close by June 30.
Gores, the chairman and CEO of Beverly Hills-based Platinum Equity, also is buying the operating rights to the Meadow Brook Music Festival.
Gores founded Platinum Equity in 1995. In its 2010 list of the 400 richest people in America, Forbes put him in a tie for 153rd with a net worth of $2.4 billion. Gores, 46, is a Flint native and has a degree from Michigan State.
New Jersey Nets point guard Deron Williams is going to have wrist surgery and will miss the final week of the season. The two-time All Star will have bone fragments and scar tissue removed from his right wrist Monday.

Williams strained his right wrist in January and the Nets were aware of it when they acquired him from the Utah Jazz on Feb. 23 in a multiplayer deal.
Del Mar adjusts purses for stakes races
Four stakes races on Del Mar's summer schedule will have their purses cut by $50,000 each when the track's 37-day meet opens July 20.
The seaside track plans to race five days a week through Sept. 7.
The races with reduced purses are the Del Mar Oaks, Del Mar Mile, Pat O'Brien Stakes and Del Mar Derby. The track says the decreases were necessary to stay within the allowed percentage guidelines for its stakes purses set by the Thoroughbred Owners of California.
The track's 11 overnight stakes races will increase in value from $75,000 to $85,000 each.
Del Mar's showcase race, the Pacific Classic on Aug. 28, will carry its usual $1 million purse.
