Ontario is lowering the starting age for colorectal cancer screening from 50 to 45, the provincial government announced on Tuesday. The change, effective immediately, is expected to increase early detection and reduce mortality rates.
Earlier Detection Saves Lives
Health officials say the move aligns with recent medical guidelines that recommend screening at age 45, especially for those with a family history or other risk factors. Colorectal cancer is the second leading cause of cancer deaths in Ontario, but when caught early, survival rates are high.
“This change will allow more Ontarians to benefit from early screening, which is crucial for successful treatment,” said Dr. Jane Smith, a gastroenterologist at St. Michael's Hospital in Toronto. “We encourage everyone aged 45 to 74 to discuss screening options with their doctor.”
How the Screening Works
Eligible individuals can receive a fecal immunochemical test (FIT) kit by mail or through their healthcare provider. If results are abnormal, a follow-up colonoscopy is recommended. The province will also expand colonoscopy capacity to meet increased demand.
The government estimates that an additional 1.5 million Ontarians will become eligible for screening under the new guidelines. Public health campaigns will promote awareness, particularly among underserved communities.
Reactions and Next Steps
Cancer advocacy groups praised the decision. “This is a life-saving step that will reduce the burden of colorectal cancer in Ontario,” said a spokesperson for the Canadian Cancer Society. “We urge other provinces to follow suit.”
The Ontario Medical Association also supported the change, noting that it brings the province in line with recommendations from the Canadian Task Force on Preventive Health Care and the U.S. Preventive Services Task Force.
