What is the Lynch syndrome (LS)?
LS is the most common hereditary bowel cancer syndrome and is the cause of approximately 1–3% of all bowel cancer. LS causes an increased risk of bowel (25-70%), ovarian (~10%), stomach (5%), womb (30-70%) , prostate (18-30%) and other cancers. It has been estimated that in Europe approximately one million people have LS. If someone has LS, regular bowel screening with colonoscopy is vital and other risk-reducing strategies will be considered. These strategies include detecting and treating an infection called Helicobacter Pylori as well as taking aspirin, and, in women, consideration of risk-reducing surgery.
