Bowel cancer, also known as colorectal cancer, is a prevalent and serious form of cancer, ranking as the second most deadly cancer in the UK after lung cancer. UK researchers in Glasgow have made significant strides in diagnosing this disease without the need for biopsies.
Traditionally, biopsies have been a standard method for diagnosing bowel cancer, involving the removal and examination of tissue samples. However, researchers at the Cancer Research UK Scotland Institute and the University of Glasgow have found that positron emission tomography (PET) imaging technology can revolutionize this process. PET scans provide detailed three-dimensional images of the inside of the body, allowing for a comprehensive examination of the entire bowel and precise study of tumours while they are still in the body. This technology, when combined with regular testing, can improve the monitoring and diagnosis of bowel cancer.
Dr. Catherine Elliott, director of research at Cancer Research UK, highlighted the significance of PET imaging in diagnosing bowel cancer, stating that it offers a promising alternative by enabling a thorough examination of the cancer landscape.
Last year, the NHS introduced DIY testing kits for bowel cancer, aiming to encourage early detection and improve survival rates. Adults over 54 in England are being sent at-home screening kits, expanding the screening to include younger adults who are not typically included. Early detection is crucial, as it can lead to earlier treatment and improved outcomes.
Symptoms of bowel cancer can include abdominal pain, unintentional weight loss, abdominal swelling, and bowel obstruction. It is essential to seek medical advice if any of these symptoms persist for three weeks or more.
Several factors can increase the risk of developing bowel cancer, including age, genetics, lifestyle factors such as diet (e.g., eating too much red and processed meat, or too little fibre), obesity, smoking, and alcohol consumption. A family history of bowel cancer and certain medical conditions can also elevate the risk.
These advancements in imaging technology and screening methods are promising steps forward in the early detection and treatment of bowel cancer, potentially saving thousands of lives.
