Table 4. Absolute Risks of Colorectal Cancer for Mutation Carriers in Hereditary Colorectal Cancer Syndromes

Syndrome Absolute Risk in Mutation Carriers 
FAPa90% by age 45 y [1]
Attenuated FAP69% by age 80 y [2]
LS40% to 80% by age 75 yb [3,4]
MYH-associated polyposis35% to 53% [5]
PJS39% by age 70 y [6]
JPS17% to 68% by age 60 y [7,8]

FAP = familial adenomatous polyposis; JPS = juvenile polyposis syndrome; LS = Lynch syndrome; PJS = Peutz-Jeghers syndrome.
aCancer risk estimates quoted here predate the widespread use of surveillance and prophylactic surgery.
bRefer to the Lynch syndrome (LS) section of this summary for a full discussion of risk.
