Sad news for fans of "Paranormal State" star Ryan Buell: He was recently diagnosed with pancreatic cancer and is undergoing treatment, according to his Facebook page.
"You all also know that Ryan is the type of person that not only likes to keep things relatively private, but wants to make sure that others are taken care of first," a staff member wrote on his page. "Ryan has been honored and humbled by the support, but also wants to make sure that we all remember the struggle is not his alone."
He's even trying to pump up others suffering from the disease.
"I know the pain that you will feel. And the pain for treatment. I still say SOLDIER ON! Let's think of one another during those moments, even though we don't know each other," he wrote on a Facebook photo.
Pancreatic cancer is sadly one of the more lethal forms of cancer, but the 30-year-old Buell has youth on his side. He's vowed to fight, just like other celebrities who have suffered from the disease.
Apple founder Steve Jobs was notoriously private about his fight with pancreatic cancer. The mastermind behind the iPhone and other must-have products didn't talk publicly about his disease before he passed away from it in October 2011.
The reason he didn't talk about it? His biographer said that he felt if he didn't acknowledge the disease it would go away.
"I think that he kind of felt that if you ignore something," Walter Isaacson said. "If you don't want something to exist, you can have magical thinking. And it had worked for him in the past."
Sadly, it didn't work that time.
"Dirty Dancing" heartthrob Patrick Swayze was still acting when he was diagnosed with pancreatic cancer in 2007. The disease quickly took hold of his body, but he vowed to fight.
"I'd say five years is pretty wishful thinking," he told Barbara Walters in a January 2008 interview. "Two years seems likely if you're going to believe statistics. I want to last until they find a cure, which means I'd better get a fire under it."
Sadly, he didn't make it until the cure: Swayze passed away from complications of the disease on Sept. 14, 2009.
"Mommie Dearest Joan Crawford was diagnosed with pancreatic cancer in the early 1970's and suffered from the disease until her death in 1977. The legendary actress gave her two younger children, Cathy and Cindy, a sum of $77,000 each from her $2 million-plus estate. Her two older children, Christopher and Christina were specifically denied money in the will.
"It is my intention to make no provision herein for my son Christopher or my daughter Christina for reasons which are well known to them," she wrote in the will, signed in 1976. Christina then published the book Mommie Dearest in 1978 that abuse she said she suffered at the hands of her famous mother. Several of Crawford's friends decried the book, but it became an international bestseller.
