Gary Sinise's son dies at 33 due to cancer

Gary Sinise announced the passing of his son, McCanna Anthony "Mac" Sinise, at the age of 33. Mac lost his battle with cancer on January 5, as shared by Gary on the Gary Sinise Foundation's website and his Instagram page.

According to Gary, Mac was diagnosed with Chordoma, a rare form of cancer originating in the spine, on August 8, 2018. Despite receiving treatment, Mac's condition worsened over time, gradually disabling him as the disease progressed.

Before his diagnosis, Mac joined the Gary Sinise Foundation as an assistant manager of education and outreach. He was also a talented drummer who performed alongside his father's band, Gary Sinise and the Lt. Dan Band. Additionally, Mac was a graduate of the University of Southern California, where he studied songwriting and composition.


Throughout his illness, Mac underwent multiple spine surgeries and eventually became paralyzed from the chest down. Despite these challenges, he collaborated with others to create an album titled "Resurrection & Revival," which was completed just before his passing.

Gary expressed his family's heartbreak over losing Mac and acknowledged the difficulties of coping with such a loss. He emphasized Mac's resilience and determination in facing his illness, noting his unwavering spirit throughout the 5 ½ years of their family's cancer fight.

Mac is survived by his parents, Gary and Moira, his sisters Sophie and Ella, their children, as well as other relatives and caregivers. Gary assured that Mac's album would be released and pressed on vinyl to honor his memory.
