Colorectal Polyps: What to Expect After Removal and Follow-Up - Surgery

Understanding colorectal polyps, particularly adenomas, is crucial for managing your health and mitigating cancer risks. It sounds like you've been proactive with your health by undergoing annual colonoscopies, which is commendable, especially since you have a history of developing polyps.
Colorectal polyps are growths on the lining of the colon or rectum, and while many are benign, some can progress to cancer over time. Adenomatous polyps, like the tubular adenoma you mentioned, are considered precursors to colorectal cancer. The risk of cancer associated with adenomas depends on several factors, including the size, number, and histological characteristics of the polyps. Low-grade dysplasia, as noted in your pathology report, indicates that the cells are abnormal but not cancerous.
In your case, since the adenoma was found to be benign, your doctor likely recommended a follow-up colonoscopy in one year as a precautionary measure. This is standard practice. The rationale behind this approach is that while the adenoma is currently benign, there is a potential for new polyps to develop or for existing ones to change. Regular surveillance allows for early detection and removal of any new or changing polyps before they can progress to cancer.

Regarding your concern about why the doctor did not remove the adenoma during the recent colonoscopy, it is possible that the polyp was small enough that the physician felt confident in monitoring it rather than performing an immediate removal. In some cases, if a polyp is very small and appears benign, doctors may opt for a conservative approach, especially if it can be easily monitored in the near future. The decision often balances the risks of additional procedures against the benefits of close surveillance.

It is also important to understand that not all adenomas will progress to cancer. The majority remain benign, especially those classified as low-grade dysplasia. However, the presence of any adenoma does increase your risk for colorectal cancer, which is why continued monitoring is essential.
In terms of follow-up, the typical recommendation is to have a colonoscopy every one to three years after the removal of adenomatous polyps, depending on the number and characteristics of the polyps found. Since you have a history of developing polyps, your doctor’s recommendation for a follow-up in one year is appropriate and aligns with guidelines for individuals at increased risk.

In summary, while it is understandable to feel anxious about the presence of adenomas, your proactive approach and your doctor's recommendations for regular monitoring are key strategies in preventing colorectal cancer. Always feel free to discuss any concerns with your healthcare provider, as they can provide personalized advice based on your medical history and current health status. Regular screenings and being vigilant about any changes in your health are the best ways to manage your risk.
