Matt Damon's father Kent is battling multiple myeloma, a blood cancer, and the 40-year-old actor recently flew to Boston to be with him and thank his doctors.
He told ABC affiliate WCVB Television on Wednesday, June 1, that while the disease is incurable, his father is doing well and will "fight it to a standstill."
Kent Damon, 68, and the actor both spoke at Massachusetts General Hospital's Cancer Care Center's One Hundred Gala on Wednesday. Kent Damon touted the success of his son, who won an Oscar for screenwriting along with Ben Affleck for their 1997 movie "Good Will Hunting," which was set in Harvard University in Cambridge, where the actor was born.
"There's the possibility that you'll look in the paper tomorrow, and there will be a picture of Matt Damon," Kent Damon said, according the Boston Herald newspaper. "He's 40 years old, and all that a dad would want in a son. He's happily married, a loving husband ... a dedicated dad to three ... no excuse me, four very fortunate daughters ... he's a caring brother. It's a wonderful ride as a dad."
Matt Damon was also joined by his wife, Luciana. The two married in 2005 and are parents to four daughters, including one from the actor's wife's previous relationship.
"How do you follow that?" Matt Damon said at the hospital event after his father finished his speech. "My dad's biggest fear is public speaking. And I'm like, you've got cancer, man!"
"Cancer has a malign indifference to who it involves," Damon added, according to the newspaper. "But I never would have guessed it would have been my dad. He's a marathoner, a college athlete, he sails up the coast. But 18 months ago, we developed a more personal relationship with Mass Gen ... and it sucked! But the care my dad has received there is just awesome."
Matt Damon's parents are divorced. He has a brother, Kyle, who is an artist. Their mother, Nancy Carlsson-Paige, is a professor of early childhood education at Lesley University in Boston.
Multiple myeloma begins in plasma cells, a type of white blood cell, which are found in the bone marrow and are a vital part of the immune system. The five-year relative survival rate for multiple myeloma is approximately 38 percent, one of the lowest of all cancers, according to the Multiple Myeloma Research Foundation.
