What disease process can mimic acute diverticulitis and should be evaluated with a colonoscopy post-symptoms?

Colorectal cancer can indeed present with symptoms that closely resemble those of acute diverticulitis, such as abdominal pain and changes in bowel habits. Both conditions can cause left-sided abdominal pain and tenderness, making it challenging to distinguish between them based solely on clinical presentation. Symptoms like rectal bleeding or anemia may also be present in colorectal cancer, further complicating the diagnosis.

Given the possibility of overlapping symptoms and the serious nature of colorectal cancer, it is crucial to evaluate patients, especially those who are older or have alarming features. A colonoscopy is the best diagnostic tool for visualizing the colon and identifying any masses or lesions indicative of colorectal cancer, allowing for tissue biopsy if needed. This approach helps determine whether colorectal cancer is the underlying cause and clarifies the treatment plan moving forward.
