Final answer:
Visible rectal bleeding and changes in bowel habits, like constipation, are clinical findings more consistent with cancer of the descending colon due to its proximity to the rectum.
Step-by-step explanation:
A clinical finding consistent with a diagnosis of cancer of the descending colon, rather than the ascending colon, might include the presence of obvious rectal bleeding or blood in the stool. This is because tumors in the descending colon are more likely to cause bleeding that is visible as they are closer to the rectum. Additional clinical findings could include changes in bowel habits, such as constipation, which could be due to the physical presence of a tumor obstructing the passage of feces.
