Matt Damon's father has died after a long battle with cancer.

Kent Damon passed away on December 14, the actor's publicist told the Boston Globe. He was 74.

The family patriarch had been diagnosed with multiple myeloma, a rare type of blood cancer, in 2010, and while promoting his new film "Downsizing," Matt revealed his father's illness had worsened in recent months.

"It's been a slow unfolding; my dad's sick, so that's a process we're going through," he told TV show Extra earlier this month. "We'll take any prayers you got, so throw 'em up there."

Kent's death occurred four days before the U.S. premiere of "Downsizing" in California on December 18. Matt skipped the red carpet event, with his representative citing a "family issue" for his absence.

The 47-year-old actor had also scrapped an appearance at the recent Britannia Awards in October.

Matt previously went public with his dad's health crisis in 2011, when father and son took part in the One Hundred Celebration in their native Boston, Massachusetts, where the movie star thanked the medical staff at Massachusetts General Hospital for their help and care.

At the time, sources told U.S. news show Today Kent was in remission.

"My family is so grateful for the care you've given us," Matt said at the event. "It's deeply humbling to see how many people here are committing their lives to helping others.

"We've lost some close personal friends to cancer in recent years, but I never thought it would happen to my dad, the marathon runner. It sucked."
