FRISCO -- It's a heartbreaking diagnosis that leaves families with little hope; doctors tell patients with terminal cancer they have months to live, with slim chances for survival.
But some patients defy those odds. Dion Raymond of Frisco is one of them.
Raymond is a man on a mission to spread his message of hope to cancer patients and their doctors.
He was in the prime of his life -- 36 years old, climbing the corporate ladder. He and his wife Sofia celebrated the birth of their daughter, Ashley.
Then it happened: A surgeon diagnosed him with glioblastoma, one of the most aggressive forms of brain cancer.
The doctor told the Raymonds Dion had little chance of surviving.
"But [the doctor] just said, 'He's going to have a really rough road, and three to six months with treatment is usually what we see with this," Raymond said.
But 12 years later, Dion Raymond is alive and thriving. He's a tri-athlete. He runs his own successful business. And his daughter is a champion figure skater.
"I knew in my heart that I had to see her grow up," said the Frisco dad.
Raymond has turned his unlikely survival from brain cancer into a personal mission: To tell patients they can also beat the odds, and to let doctors know they should be in the business of providing hope, not timelines on life.
"Don't take away people's hope," he said. "While you're breathing, you still are able to have hope. And with hope, starts everything else."
His wife agrees, and said doctors should not give patients timelines.
"Who is it that defines how long you have on this earth, really?" she said. "It's the man up there."
Dion Raymond has taken his message of hope to cancer patients and a conference of international oncologists. He said with any kind of adversity, it’s hope that gives us something to grab on to... and something to live for.
