Dennis Farina was being treated for cancer

Dennis Farina’s doctor says the actor died while being treated for lung cancer.

Farina, who died Monday after suffering a blood clot in his lung, had been under treatment for the cancer for several months, according to his cardiologist, Dr. Marc A. Kates.

Thirteen years ago Farina had been diagnosed with “a small cancer that was treated and cured with surgery,” Kates said in a statement on Tuesday.

But in recent months the cancer had recurred and, despite ongoing treatment, the blood clot “unexpectedly and suddenly took his life,” Kates said.

The 69-year-old Farina, who died in a Scottsdale, Ariz., hospital, was known for such films as Get Shorty and Out of Sight, and for TV series including Law & Order and Luck.
