Lynch syndrome is a genetic condition that makes people more likely to develop certain cancers. People who have it also have about a 40% to 80% chance of getting colorectal cancer by age 70. They’re also at risk for cancers of the uterus, ovaries, and stomach. And they tend to get cancer at younger ages than other people, often in their 30s and 40s.
Lynch syndrome is sometimes called hereditary non-polyposis colorectal cancer (HNPCC). Other forms of the condition are Muir-Torre and Turcot syndromes, both of which put a person at higher risk of other cancers, and in the case of Muir-Torre, skin lesions.
What Causes It?
It comes from changes in genes that can be passed down in families. If one of your parents has it, you have a 50% chance of getting it too.
How Is It Diagnosed?
We will take a detailed family history to see how many of your relatives have ever had colon cancer. If you’re high risk, we can order genetic counseling and DNA testing through Myriad, one of the sponsors of this event.
If one person in your family is diagnosed with Lynch syndrome, your other relatives may want to get tested.
