Colorectal cancer in Ethiopia: Epidemiological trends, diagnostic and laboratory capacities, and challenges

Colorectal cancer (CRC) refers to cancer that develops in the colon or rectum, parts of the large intestine. It ranks as the third most prevalent form of cancer globally. Colorectal cancer is responsible for the morbidity of millions and the loss of hundreds of thousands of lives worldwide although the incidence varies significantly depending on geographical location. In recent years, CRC has decreased in high-income countries due to technological advancements in diagnosis and treatment. However, there is an increased occurrence of CRC morbidity and mortality in low- and middle-income countries. Colorectal cancer is becoming an emerging public health concern in Ethiopia. We noticed that the incidence rates have been lower compared to more developed countries, but recent years have seen a noticeable increase. This rise is attributed to factors such as changes in diet, lifestyle, and an aging population. Common risk factors include dietary shifts towards processed foods and red meat, physical inactivity, obesity, smoking, and alcohol consumption. Unfortunately, in Ethiopia, screening programs for CRC are not widespread, and limited access to diagnostic facilities, lack of public awareness, and insufficient healthcare infrastructure contribute to late-stage diagnoses or left without diagnosis. Treatment options, including surgery, chemotherapy, and radiotherapy, are available but not uniformly accessible across the country, posing challenges for timely and effective treatment. Addressing colorectal cancer in Ethiopia requires a comprehensive approach to enhance public awareness, improve screening and early detection, expand treatment facilities, and train healthcare professionals to provide effective care.
