Lynch syndrome

 

Lynch syndrome (HNPCC or hereditary nonpolyposis colorectal cancer) is an inherited genetic condition that has a high risk of colon cancer as well as other cancers including endometrial cancer ovarian and stomach cancer. If certain cancer-fighting genes are broken or mutated, you may be at higher risk for these conditions.

Testing for lynch syndrome can be done through a saliva sample. If the conclusions of the test show a mutation in the MLH1, MLH2, MSH6, EPCAM or PMS2, you are considered to have Lynch syndrome. Individuals with Lynch syndrome have an up to 82% change of getting colorectal cancer and women have an up to 71% of uterine cancer. These risks can be reduced by having more frequent colonoscopies, ultrasounds, and even surgery if necessary.

If you have Lynch syndrome, sharing the information with your family is very important because direct relatives have a 50% chance of having the same mutated gene. Hereditary cancer testing is the only way to know who has the broken gene in the family.
