The purpose of this booklet is to provide information about an inherited type of colon cancer that may be more common among men and women of Ashkenazi Jewish heritage (Jews of Eastern European or Russian ancestry). The information provided is intended to add to, and is not a substitute for, discussions with doctors, genetic counselors, nurses, and other members of the health care team. We encourage you to read the entire booklet in the order in which it was written, since each section is built upon information in preceding sections. We emphasize the need for regularly scheduled, thorough medical examinations for persons who already have had colorectal cancer. Equally important, relatives at risk for this condition need to have regular examinations. For additional information you are encouraged to contact your own personal health care provider or the Hereditary Colorectal Cancer Registry at the Johns Hopkins Hospital, (410) 955-3875 or toll free 1-888-77COLON (772-6566).
