Our bodies are made up of about 30 trillion cells that together form our tissues and organs. As the body grows and ages, these cells go through trillions of replications and divisions.
Behind the wheel of all this complex growth and division is our DNA, the instruction manual that tells cells how to make and do everything they need to do.
Sometimes this genetic code gets errors.
Most of the time, the body’s highly effective proofreading system goes through and fixes these errors. But sometimes, they’re left unchecked. The resulting cells, which often grow at unexpected and dangerous rates, can become tumors.
When a tumor develops in the colon or rectum, we call this colorectal cancer (CRC).
