The Amsterdam criteria are used to identify families with Lynch syndrome (also called HNPCC) based on their family history. 

Nonetheless, only about 40% of HNPCC affected families fit these criteria. This means that the Amsterdam criteria cannot tell for sure if your family has (or not) the disease.

They are, however, a good indicator for the need to be genetically tested 

Check if your family fits the following criteria: 

_{Check if your family fits the following criteria:} 

• At least 3 relatives with HNPCC*, with one of them being a first-degree relative of the other 2;
• At least two successive generation affected;
• At least one of the relatives with an HNPCC* linked cancer diagnosed before the age of 50
