Can colon cancer develop in 3 years?

Does the size of a polyp indicate cancer?
The size of the polyp correlates with the development of cancer. Polyps less than 1 centimeter in size have a slightly greater than a 1% chance of becoming cancer, but those 2 centimeters or greater have a 40% chance of transforming into cancer.
Do colon polyps grow slowly?
Colon polyps are clumps of cells that form in the lining of the colon. They grow slowly over time and typically do not cause symptoms, particularly when they are small. In time, however, some large polyps may cause bleeding into the colon.
How long does it take colon cancer to go from Stage 1 to Stage 4?
Colon cancer, or cancer that begins in the lower part of the digestive tract, usually forms from a collection of benign (noncancerous) cells called an adenomatous polyp. Most of these polyps will not become malignant (cancerous), but some can slowly turn into cancer over the course of about 10-15 years.
