Blood test for colon cancer risk

A university researchers are developing a simple blood testbthat can help doctors determine who needs a colonoscopy, a sreening procedure for colon cancer recommended for adults who is above fifty years of ages. The new test, which looks for cancer related protiens in the blood, identifies colon cancer and precancerous polps almost as well as a colonoscopy, according in the study published.

The cancer researchers say the test won't replace colonoscopy but might provided a non-invasive means of identiflying high risk patientsand an incentive for them to undergo the more invasive procedure. Parts of whatwe are trying to do here is use blood markets for cancer like we do cholesterol levels to predict heart diaease risk

The cancer researchers said if he could tell you that you have a 92% changes of having colon cancer, you might be more willing to undergo a colonoscopy. The blood test might also reduce the overall number of people who needs colonoscopy by screening out low risk patients.
