Hereditary nonpolyposis colon cancer
====================================

* Robin S. McLeod

We appreciate Edmond Lemire's comments and agree that people with hereditary nonpolyposis colon cancer have an increased risk of extracolonic malignancies. However, the recently published recommendations from the Canadian Task Force on Preventive Health Care1 were limited to screening for colorectal cancer in people at average and high risk. Thus, screening for other types of cancer, even in people with hereditary nonpolyposis colon cancer, was beyond the scope of this review.
