The 79-year-old revealed he was diagnosed with stage 4 pancreatic cancer in March.

"Now normally, the prognosis for this is not very encouraging, but I’m going to fight this, and I’m going to keep working," he said in a video at the time. "And with the love and support of my family and friends and with the help of your prayers also, I plan to beat the low survival rate statistics for this disease."
