To call attention to colorectal cancer -- Canada's second biggest cancer killer -- the Colorectal Cancer Association of Canada has set up a giant walk-through colon at the World Congress of Gastroenterology in Montreal.
The colon -- designed and built in Brazil -- is a 31-metre model that members of the public can go through to see the entire process of what happens inside the colon.
Volunteers will answer questions about the colon and cancer.
After the Montreal visit ends on Sept. 14, the giant colon will be sent to Toronto, Calgary and Vancouver for more public tours.
The Colorectal Cancer Association estimates that 19,600 Canadians will be diagnosed with colorectal cancer and 8,400 will die from it in 2005.
One in 14 men and 1 in 16 women are expected to develop colorectal cancer during their lifetime. The association says that colorectal cancer is 90% treatable if detected early.
