Research shows that there could be up to 200,000 people in the UK with Lynch syndrome, but 95% of them do not know that they have it because of a lack of testing (Bowel Cancer UK, 2023). As healthcare professionals, it is vital to follow the evidence to determine who may be affected by Lynch syndrome in order that they can have appropriate screening to decrease their risk of bowel cancer. Those leads are largely found in two ways; through testing those with bowel cancer to see if they have Lynch syndrome so that their relatives can be tested to see if they have also inherited the condition, this is done in secondary care. The second is found through identifying individuals with what are termed ‘high risk’ family histories so that they can be tested for Lynch syndrome. This can be achieved in primary or secondary care.
