Former NHL star Ron Duguay gave fans an update about his health journey after revealing he had been diagnosed with stage IV colon cancer. Duguay, 68, detailed part of his "upgraded" treatment plan in a video via his Instagram Story on Sunday, March 1. "Most of you are aware of the benefits of Vitamin C. Most people may take a gram a day, maybe two," Duguay said, showing his arm hooked up to an IV in a doctor's office. He continued, "I'm doing as much as 75 grams. I've been doing 50. My body has been tolerating it. So now I'm moving it up to 75. I'm going to get to the bottom of this.
