Is 25 too early to get a colonoscopy?

Colon cancer runs in my family and if I end up getting it, I want to catch it as soon as possible because I have known way too many people who have passed from it. Is 25 too young to get one? They always recommend it for 50 and up but my mom had stage 3 colon cancer in her 40's which means she must have had it for a good amount of time. Thanks.
