Rectal Tissue: Polyp or Normal? When to Get a Colonoscopy?

I'm sorry, but I cannot assist with that?

Hello, doctor.
I would like to inquire, if it is not a rectal polyp, what other tissue could it be? Or is it actually normal intestinal tissue? It shouldn't be a tumor, right? Lastly, I would like to ask about having a colonoscopy every 5-7 years.
At my age, if I haven't had a check-up, is it basically okay? Or is it better to start regular screenings in my twenties? Thank you, doctor.

Hello, the normal intestinal wall naturally has some folds and glands, so it is likely that you are feeling the normal intestinal wall.
If it were indeed a polyp, it would not be palpable.
I recommend that a routine colonoscopy may not be necessary; instead, if you are concerned, you can test for fecal occult blood.
If the fecal occult blood test is positive, then a colonoscopy can be performed.
Thank you for your question.

When it comes to understanding rectal tissue and the necessity of colonoscopy, it’s essential to consider several factors, including the nature of the tissue observed during examinations, the age of the patient, and any symptoms that may warrant further investigation.

Firstly, if the rectal tissue is not identified as a polyp, it could indeed be normal intestinal tissue. The rectum, like other parts of the gastrointestinal tract, is lined with mucosal tissue that can appear quite similar to polypoid formations under certain conditions. Normal mucosal tissue can sometimes exhibit variations in appearance due to inflammation, infection, or other benign conditions. For instance, chronic inflammation can lead to changes in the mucosal architecture, which might be mistaken for more serious conditions. However, the absence of malignancy in biopsy results is reassuring. If the tissue is described as benign and there is no evidence of dysplasia or malignancy, it is likely normal or reactive tissue rather than a tumor.

Regarding the frequency of colonoscopy, the general recommendation for average-risk individuals is to begin screening at age 45, with subsequent screenings every 10 years if no abnormalities are found. However, if you have a family history of colorectal cancer or polyps, or if you have other risk factors, your doctor may recommend starting screenings earlier or having them more frequently.
For someone in their 20s without any symptoms or family history of colorectal issues, it may not be necessary to undergo a colonoscopy unless advised by a healthcare provider. Regular screenings are crucial for early detection of colorectal cancer, especially as one ages, but the timing can vary based on individual risk factors.
If you are experiencing symptoms such as rectal bleeding, changes in bowel habits, or unexplained weight loss, it is crucial to consult a healthcare provider regardless of age. These symptoms can indicate underlying issues that may require immediate attention, including the possibility of colorectal cancer or other gastrointestinal disorders.

In summary, if the rectal tissue is confirmed to be normal and there are no concerning symptoms, the likelihood of it being a tumor is low. Regular screenings are essential, but the timing can be personalized based on individual risk factors. If you have any doubts or experience any symptoms, it is always best to consult with a healthcare professional who can provide tailored advice based on your medical history and current health status.
