Controversial: Colon cancer would start as microscopic cells that are unable to be detected by any test. Some reports suggest that a colon cancer has been present for 20 years or more before even a small tumor can be seen and located. The cell type and tumor dna tell more about how fast it may grow, invade, or spread once the tumor forms. So changes from one stage to another is highly variable.
