Stan Walker has announced an upcoming documentary in which he looks set to address his recent health scare in "his most personal story yet".
The feature-length event, Stan, was announced today at a Mediaworks event where the trailer debuted. It showed Walker with a medical dressing across his abdomen saying, "I just thank god every day that I'm alive."
The Herald understands Walker has had his stomach removed.
Last year, Walker discovered he has a rare cancer-causing gene mutation which runs in his family. The aggressive CDH1 mutation was responsible for his mother's breast cancer and reportedly for the deaths of at least 25 of his family members.
It's estimated 70 per cent of those who have the mutation will develop stomach cancer by age 40, so stomach removal is often the recommended treatment.
