Gary Sinise shared the heartbreaking loss of his son, Mac, who passed away on January 5, 2024, at 33, after battling chordoma, a rare bone cancer. Mac’s diagnosis came shortly after his mother, Moira, was diagnosed with stage-three breast cancer in 2019. While Moira survived, Mac’s cancer returned after surgery, and Sinise paused his career to care for him during his treatment.

Sinise described Mac’s battle, saying the tumor appeared like a “monster” on the MRI. Despite the struggles, Sinise remained hopeful, focused on supporting his son. Tragically, Mac lost the fight, passing peacefully surrounded by family.

Sinise, deeply affected, has since chosen to prioritize his family, focusing on healing and cherishing the time with his loved ones. He expressed that his time in the spotlight may come later, but for now, family is his priority.
