Alex Trebek is trying to help others who might be experiencing early symptoms of pancreatic cancer.

The Sudbury-born 79 year old Jeopardy host was diagnosed with pancreatic cancer last March.

Trebek has created a global public service announcement for World Pancreatic Cancer Day on November 21st, joining 80 organizations from 30 countries to raise awareness of the risks and symptoms.

“I wished I had known sooner that the persistent stomach pain I experienced before my diagnosis was a symptom of pancreatic cancer,” Trebek says in the announcement, adding that other common symptoms include “mid-back pain, unexplained weight loss and the yellowing of the skin or eyes.”

In the PSA, he points out that pancreatic cancer still has an abysmal single-digit five year survival rate in most countries.

Trebek and WPCD (World Pancreatic Cancer Day) ask that the world join him in raising awareness by wearing purple this November 21st, and sharing the hashtag #WPCD on social media, or tagging @worldpancreticcancerday that day on Facebook, Twitter or Instagram. You can also ask your public health officials to support more government funding for pancreatic cancer research.

“Together, we can get it done,” says Trebek.

Our own Libby Znaimer is a pancreatic cancer survivor, one of the few to live long past the five year survival rate.
