Actor Gary Sinise's son, McCanna Anthony Sinise, died last month at the age of 33, the actor announced Tuesday.

"Mac" had struggled with Chordoma, a rare form of cancer for years. He underwent a surgery to remove the first tumor in 2018 and a second procedure the following year, though the Chordoma persisted and gradually saw him deteriorate, the actor stated in a tribute to his son.

Mac was first diagnosed after joining the Gary Sinise Foundation. He often played as a drummer in his father's Lt. Dan Band, a musical project named for his father's iconic role as Lt. Dan in the film "Forrest Gump."

"Like any family experiencing such a loss, we are heartbroken and have been managing as best we can. As parents, it is so difficult losing a child," Sinise said. "My heart goes out to all who have suffered a similar loss, and to anyone who has lost a loved one. We've all experienced it in some way."

Sinise further touched on his son's Catholic faith, including his son's favorite quote from St. Augustine: "You have made us for yourself oh Lord, and our hearts are restless until they rest in you."

The actor also confirmed that his son's final musical album "Mac Sinise: Resurrection and Revival" will soon become available.
