Matt Damon is a wonderful actor, but it seems like there's something else he is even better at - being a good son.

"He's all you could ever for ask for in a son," Damon's father, Kent, said after completing cancer treatments in 2011. "It's been a wonderful ride being his dad."

At the time, Kent was diagnosed with multiple myeloma, a rare form blood cancer, and had to undergo a few rounds of treatment at the Massachusetts General Hospital. Matt dropped all his commitments to be by his father's side, and support him through the ordeal.

The Good Will Hunting star admitted that although he and his family have "lost some close personal friends to cancer in recent years," they "never thought it would happen to my dad, the marathon runner. It sucked."

Kent, 68, went into remission a few months later, and Damon once again flew home to Boston to extend a personal thank you to the doctors who treated his father.

"My family is so grateful for the care you've given us," Damon said during the hospital's One Hundred Celebration at the Westin Hotel. "It's deeply humbling to see how many people here are committing their lives to helping others."

Six years after his father won his battle against the fatal disease, the actor has once again been forced to cancel work commitments, including attending the BAFTA Awards to be with his family after receiving the unfortunate news of Kent's cancer recurring.

Damon recently opened up about the severity of the situation in an interview with Extra.

Damon found out about Kent's condition back in October, and immediately skipped out on the 2017 Britannia Awards in England, where he was to be presented with the Stanley Kubrick Award for Excellence in Film.

"It's been a slow, unfolding, my dad's sick, so that's been a process we're going through," Damon told Extra.

Damon did not reveal what stage the cancer is at, but he said "We'll take any prayers you got, so throw 'em up there."

Myeloma often exhibits no symptoms until it's advanced. At that point, a person starts experiencing bone pain, infections, bleeding, and anemia. Although it is hard to cure, and doctors often give patients an average of 4 years to live, some people beat the odds.

Kent had already beaten cancer once, so he can surely do it again with his supportive son by his side.

We'll be praying for his swift recovery.
