In brief: Varies
The "family history" of colon cancer needs to be further clarified as to what type of family syndrome this is.
A genetic counselor can help further define the risks and potential surveillance or treatment strategies. The increased risk may be small or may be very large. Specific genetic testing may be indicated.

In brief: Double the risk
If there is personal family history then the risk of getting colon cancer is usually double than that of the general population.
If your family member was young when he/she developed colon cancer then you should have your screening colonoscopy done 5-10 years before the age that your family member developed cancer.

In brief: About 10%
A family history of colon cancer, especially in a close relative, increases the risk of cancer 10% above the general population.
If the relative was diagnosed at a younger age (40's) then the risk is slightly higher.
