Stan Walker has released a new trailer for his upcoming documentary detailing his serious health battles over the past year, this time focusing on the emotional toll the ordeal has had on his mum.
The documentary Walker follows the Kiwi singer through the process of treatment and surgery for a rare cancer causing gene that runs in his family.
But as Walker says in the new trailer, the guilt and fear his mother has endured also played on his mind.
"It's been hard for my mum, she cries everyday and she blames herself too," Walker says.
"What if there's complications, that's how I die."
The trailer also features an interview with his mum.
"I'd rather me go before my children, anyone would, any mother and father would," she said.
Walker posted the Stan trailer to his Instagram page yesterday, also hitting out at nasty speculation last year about the causes of his sudden weight loss.
"I bet half the people thinking i was on crack or whatever y'all were saying are feel pretty dumb right now 😂😂😂," Walker wrote.
"Ah well, we are all know it alls sometimes & just make up stories 😂😂😂 its allgood.
"This is bigger than all the talkers talking."
The gene mutation is responsible for the death of 25 members of his family.
It is understood that Walker has had his stomach removed as a result.
The genetic mutation which runs in Walker's family is expected to cause stomach cancer in 70 per cent of people by the age of 40.
