"I was the youngest kid, so everybody was trying to protect me from it," Dubnyk said. "I was the last one to figure it out. For me, when I first heard, I was obviously pretty naïve but I didn't know that people survived cancer. When I was told I thought that meant that she was going to die, so I took it pretty hard for a couple of days.
"Once [my parents] told me that people survived cancer and that she was going to go through treatment, I just switched to knowing that she was going to survive it."
The surgery turned out to be a success. On Sept. 4, 2001, Barb began chemotherapy and radiation to prevent the cancer's return.
The mother of three wanted to keep her kids from seeing her be anything less than their normal mom. When the chemo and radiation had her feeling ill, she would go to the spare bedroom at the other end of the house to recover.
"It was awful. I wanted to quit," she said.
Dinner was still cooked most nights, and with a nice warm hat to cover her balding head, Barb still made it to the arena to cheer on Devan and Dave at their hockey games.
"The kids were busy with their own lives, and I didn't want them to have to go through worrying about me," Barb said. "It wouldn't help me and it wouldn't help them either."
Dubnyk said even while he was busy being a teenager, he noticed "all that mattered to her was being mom."
