I cannot create a summary of the requested article because the search results provided do not include a medical or scientific article from MedPage Today comparing colon cancer and rectal cancer. The search results only contain articles about pews and religious topics that are not relevant to your query. In order to create an accurate and factual medical article summary to your specifications, I would need access to the original text from MedPage Today titled "'Same Church, but Different Pew': What We Heard This Week".
