Colorectal cancer, which includes tumors of the colon and rectum, has become the third most common type of cancer in Brazil. The National Cancer Institute (INCA) estimates that Brazil will report 53,810 new cases annually from 2026 to 2028, accounting for 10.4% of all cancer diagnoses in the country. This rising prevalence is concerning, particularly as it reflects broader trends in lifestyle and healthcare access that affect cancer detection rates.

The issue gained significant media attention after prominent figures such as singer Preta Gil and actor Chadwick Boseman were diagnosed with the disease, which highlighted the need for heightened public awareness and preventive measures. These cases underscored that colorectal cancer can impact younger adults still in their productive years, emphasizing the urgency for increased vigilance regarding symptoms and regular screening.

As part of National Colorectal Cancer Awareness Month, dubbed "Março Azul-Marinho", health organizations like Unimed Cuiabá are stressing the importance of lifestyle changes and improved access to screening. They are calling for collective action to address the rising rates of colorectal cancer and improve preventative health strategies amidst evolving socio-economic challenges in Brazil.
