The Claim from the blog:
Penny Heals Stage 4 Pancreatic Cancer Naturally!
Update: It is my understanding that Penny passed away sometime after March 2014, as that is the last time she posted on social media. I have not been able to gather any details as to the cause of her death. If she did in fact die of cancer, it is worth noting that the median survival rate of stage IV pancreatic cancer is 2-6 months with conventional treatment. Penny thrived for nearly 3 years after her stage IV pancreatic cancer diagnosis. That is incredible.
The original post about Penelope Villabert’s claim to have healed herself of pancreatic cancer debuted in November 2012. This is the original post. According the Internet Wayback Machine, this post ceased to exist on Wark’s site on September 4, 2016 with a “404/Page Not Found” error message.  Chris appears to have resurrected the blog post recently, with the update, likely in response to the recent publication of this Youtube video exposing the deaths of “healed” survivors that mysteriously disappeared from his blog and Youtube channel.
A 3-second google search finds that Penny died at CEBU DOCTORS HOSPITAL, Philippines on 13 August 2015.

b : to make well again : to restore to health heal the sick
For Chris to have declared, with certainty, that Penelope Villabert “HEALS” stage 4 cancer naturally is exceptionally misleading. There is nothing incredible about death or misleading people into having false hope that they can “HEAL” stage 4 cancer if they buy Wark’s video series, and buy the supplements that are affiliate linked in these testimonials. Chris has a word for this situation, it’s called “failure”:
“A successful treatment means being cured of cancer with no recurrence.
Complete long-term restoration of health is success.
Sickness and death are failure.” – Chris Wark 
In order to pull some sort of victory from the ashes of failure, Wark makes Penny Villabert’s life extension an issue of conventional medicine versus alt-med by adding 3 words to a sentence that does not appear in the resource materials. Chris added “with conventional treatment” despite the fact that the resource page he cited does not mention the words “conventional treatment” or any mention of treatments options pertaining to survival other than surgery.
Median survival is the length of time from either diagnosis or treatment, to the point at which half of the patients are still alive. So while the median survival rate is 2-6 months, 50% of them are still alive. According to the site Chris linked to in his update, generally for adults with pancreatic cancer in England and Wales :
Almost 5 out of every 100 (almost 5%) survive their cancer for 5 years or more
Only 1 out of every 100 (1%) will survive their cancer for 10 years or more after diagnosis
Some people live much longer than 5 years.
Penny’s survival is not unusual or “incredible” and there is no evidence that her holistic treatments can be credited.
And lastly, Chris disrespects the deceased by continuing to have two undisclosed Amazon affiliate links  embedded in Penny’s story. Even in death Chris financially exploits her.
