Kevin McHugh, 47, was diagnosed with pancreatic cancer in 2010.

"He came home from the doctor's appointment, and I was cooking lunch in the kitchen," his wife, Tammy McHugh told ABC News. "I could tell by the look on his face that something was wrong."

She continued: "He said, 'I have cancer.' At first, I thought he was kidding. And he said, 'No, I have cancer.' The kids came home from school, and we were all silent. It was just somber."

After years of chemotherapy, doctors recommended Ken focus on living his final days comfortably.

"The doctors are hesitant to give an exact time frame, but they are saying this is the last turn of the season and to get anything done that he wants to get done," said Tammy.

Ken told his wife one of his dying wishes was to walk his four children down the aisle.

"The most horrible and emotional thing my wife and I have ever had to do was to tell our children I was dying," Ken wrote on his GoFundMe page. "To tell them I wouldn't see them all turn into teenagers, wouldn't see them graduate high school, get married– that I wouldn't walk any of my three beautiful daughters down the aisle or get to hold and spoil any of their children, my grandchildren."

With the help of Team CMMD, a Pennsylvania-based cancer foundation, Ken was able to walk his daughters Samantha, 19, Julia, 15 and Kathryn, 14, and son Dylan, 17, down the aisle on Oct. 3. The organization planned the event in just six days, arranging a deacon, a chapel, a limousine, flowers, dresses, tuxedos, a videographer, music and a cake.  

"He walked them down the aisle and read them a letter he wrote to each of them talking about how they came into this world, reflecting on their persona and character and what he sees for them in the future," said Tammy. "Even though he won't be there, he will always be by their sides."
