Actor Gary Sinise shares tribute to son, Mac, after 33-year-old died of rare cancer

Mac Sinise was first diagnosed with chordoma in August 2018. He underwent multiple spine surgeries to remove the initial tumor, but the chordoma returned and began to spread.

According to the National Cancer Institute, one in a million people worldwide are diagnosed with chordoma each year. Chordomas are difficult to treat because they grow “near important tissues like nerves and blood vessels.”

The cancer left Sinise paralyzed from the chest down, but he used his limited mobility in his right arm to pursue his passion project — in his final year, Sinise dedicated his time to creating music with an old friend and his father’s bandmates.

Sinise recorded two pieces, one unfinished from his college days and another on the harmonica, which he learned to play while undergoing medical treatment. His success inspired Sinise to create an entire album.

The album titled, “Resurrection & Revival,” will be available soon.

“He gave his family and friends so much during his 33 years, and he accomplished great things in those final months,” Gary Sinise wrote. “Thank you, Mac. You did it. Resurrection & Revival will live on. And so will you. In our hearts forever.”
