Colorectal cancer (CRC) is one of the few cancers where prevention is possible through effective screening, particularly colonoscopy. Recent changes in guidelines now recommend starting screening at age 45 due to rising cases in younger individuals, with particular concern for early-onset CRC in South Africa’s diverse population. The effectiveness of colonoscopy relies not only on early detection but also on the specialist’s skill and the use of complete polypectomy rather than biopsy alone. Advances in technology, such as robotic surgery, further enhance outcomes in complex cases, and medical aid schemes are increasingly recognising and funding preventive screening. Choosing a specialised, evidence-based approach offers patients the best protection against CRC.

We understand that undergoing a colonoscopy may seem daunting or unfamiliar to you. However, rest assured that it is a routine procedure performed to detect and prevent colorectal diseases. This introduction aims to provide you with valuable information about colonoscopies, helping you feel informed and prepared for the procedure.
