In brief: From polyps usually

Almost all colon cancers start off as a polyp, hence the push for colonoscopy screening looking for polyps.
Only 20% of colon cancers are hereditary, meaning the rest are environmentally related to foods we eat and chemicals we are exposed too. If you are over 50 or have risl factors get regular colonoscopies.

In brief: Starts as pre-cancer

Colon cancer often starts with a small pre-cancerous growth, called a polyp.
Most of the time these take many years to grow into a cancer. But there are probably some colon cancers that grow much more quickly, and we are still learning the details on this.
