Ontario lowers colorectal cancer screening age to 45 years

Toronto —
The Ontario government announced that it will lower the starting age for routine colorectal cancer screening from 50 to 45 years, in a change aimed at detecting the disease at earlier stages and improving treatment chances.

Under the amendment, residents of the province aged 45 will become eligible to enter the organized screening program, instead of waiting until the age of fifty as was previously practiced.

The decision comes amid growing concerns about rising rates of colorectal cancer among younger adults, a phenomenon that has prompted health authorities to reassess the age to start preventive screenings.

The screening usually relies on a home test to detect early indicators that may require additional tests, including colonoscopy when needed.

Health authorities say that early detection remains a crucial factor in improving outcomes, as the disease is more effectively treated when discovered before it spreads.

Lowering the screening age is expected to increase the number of those eligible for the program, which may raise demand for tests and medical follow-up, but it may also help detect early cases that would have remained undiagnosed for years.

The step is part of a broader trend to enhance prevention and early screening of cancer diseases in the province, focusing on reaching the most vulnerable groups and updating public health programs according to changing disease patterns.
