Scientists at The Institute of Cancer Research and London Research Institute, funded by Cancer Research UK, have identified two new genetic variants that increase a person’s risk of getting bowel cancer. Their findings are published in this month’s Nature Genetics*.
These results, combined with genetic variants found in previous studies, have identified a group of people who are four times more likely to get bowel cancer. The significance of these results is that once a test has been developed, this group of people would be suitable for intensive screening for the disease.
The teams carried out a 'whole genome search' to pinpoint the two genetic variants, which are located on chromosomes 10p14 and 8q23.3.
In the UK, more than 36,000 people are diagnosed with bowel cancer each year and around 16,000 people die.
Professor Richard Houlston, joint lead researcher based at The Institute of Cancer Research, said: "This is an exciting development in our understanding of how bowel cancer develops. By pinpointing individuals at a significantly increased risk of the disease we can begin to develop techniques for targeting screening. Ultimately we hope to reduce the number of people dying of this disease.”

- Every year in the UK, around 36,000 people are diagnosed with bowel cancer. It is the third most common cancer after breast and lung and the disease causes almost 16,100 deaths in the UK every year.
- Around two-thirds of cases are in the large bowel (colon) and the remaining third are in the back passage (rectum). The occurrence of bowel cancer is strongly related to age, with over 80 per cent of cases arising in people who are 60 years or older.
About The Institute of Cancer Research
- The Institute of Cancer Research is Europe’s leading cancer research centre with expert scientists working on cutting edge research. It was founded in 1909 to carry out research into the causes of cancer and to develop new strategies for its prevention, diagnosis, treatment and care. Website at: www.icr.ac.uk.
- The Institute is a charity that relies on voluntary income. The Institute is one of the world’s most cost-effective major cancer research organisations with over 90p in every £ directly supporting research.
