"Stage 0 colon cancer is the earliest stage possible and is also called carcinoma in situ. &amp;quot;Carcinoma&amp;quot; refers to cancer that starts in epithelial tissue and &amp;quot;in situ&amp;quot; means original position or place. Colon cancer is considered stage 0 when it hasn&amp;#39;t moved from where it started; it&amp;#39;s still restricted to the innermost lining of the colon."^^<http://www.w3.org/2001/XMLSchema#string>
