It's indisputable that colonoscopy screening procedures save lives. If detected early, abnormal cells can be removed before they even become cancerous, with little to no chance of a reoccurrence. Yet, in the later stages of cancer, the five-year survival rates can drop to as low as 7% if left unchecked.
