In brief: Varies. ~10yrs
In general, we think about 10 years.
Hence the "standard" colon screening recommendation (by colonoscopy) of every 10 years if the colon is well prepped and without pre-cancerous polyps. Colon cancer can grow faster especially in some familial syndromes. Individuals with polyps may and likely do need more frequent followup. Recs individualized by the GI physician.

In brief: Years
Colon cancers generally start as colon polyps and it takes several years for a polyp to become cancer.
This is true most of the time, but not always.
