Before molecular genetic diagnostics came of age in the 1990s, a comprehensive family history was the only basis on which familial risk of colorectal cancer could be estimated. In the case of hereditary nonpolyposis colorectal cancer (HNPCC), also known as Lynch syndrome, the historic perspective offered by Warthin in 1895 has not changed appreciably (1). Warthin's seamstress confided to him that one day she would die of cancer of the colon or of the female organs, "because everyone in my family died of these diseases." Her prophecy proved accurate because she died of endometrial cancer at a relatively young age. In 2007, many patients still base their expectations and plan their behaviors around a similar sense of fatalism, and little else.
The seamstress's family, now known as family G, was subsequently updated (2) following the report of two strikingly similar families, which, for the lack of
