The Parkerville resident has hired the Kookaburra Cinema in Mundaring next month to show the documentary series The Truth About Cancer: A Global Quest.
Ms Wallis became interested in natural prevention and treatment of the disease after a skin cancer diagnosis and members of her family being affected by the illness.
“We all know people who’ve had cancer and I want to help people before they get cancer, to provide another perspective on the illness,” she said.
The documentary by American medical researcher, author and health freedom advocate Ty Bollinger explores different approaches to cancer prevention and treatment in nine episodes.
Ms Wallis said the complete series would be screened free-of-charge every Thursday night over five weeks, if sufficient demand followed the first screening on February 11.
In the series, Bollinger sets out to find out more about cancer, its causes and treatment after losing several relatives, including his parents.
He travels the world interviewing more than 130 doctors and researchers, and meets cancer survivors who have chosen holistic care.
Ms Wallis, who previously worked as a doctor’s receptionist, has bought the series, currently free to view online.
She hopes the film will reach more people at a public screening.
Ms Wallis said she was not against conventional cancer treatments but she believed people need to take control of their health care.
She said she had read extensively on the subject and encouraged families to familiarise themselves about the cancer risks associated with high sugar and processed foods.
