Pathological sections of intestinal polyps that reveal highly heterogeneous cells may lead to a visit to gastroenterology or oncology to speak with the attending physician and undergo the necessary investigations such as tumor marker tests, rectal, pelvic high-resolution MRIs, and PET-CTs to further clarify the medical condition in order to determine a specific management plan. After a patient undergoes colonoscopic polyp removal, a polyp pathology biopsy is typically performed. Highly heterogeneous cells, which are cells that differ greatly from normal cells, indicate that the patient’s intestinal polyp has the potential for malignant transformation. Tumor marker tests such as carcinoembryonic antigen, rectal and pelvic high-resolution MRI, and PET-CT can be performed to clarify the development of the disease and to determine the next step in the treatment plan, such as close follow-up and surgical resection of the diseased intestinal segments. Highly heterogeneous cells do not mean that cancer has occurred, and patients should maintain a positive and optimistic mindset and cooperate with the doctor to complete the examination and treatment. Patients are advised to consult the doctor promptly if they feel unwell, and not to make blind decisions on their own to avoid delaying their condition.
