Hi, Thanks for writing in. It is important to confirm the pathological diagnosis of the cauliflower type growth. The growth has transformed from low grade dysplasia to high grade means that there might be active cell division which is a precursor to cancer. In such cases it is better to do a CT scan of abdomens and pelvis and colonoscopy. This will show any more early growths and give a complete picture of the nature of illness. The treatment for high grade dysplasia is surgery and regular follow up to prevent cancer from taking place. Once cancer occurs then it gets difficult to treat. Please take the patient to a cancer research institute and then get a complete cancer screening examination done in view of high grade dysplasia in rectum. Certain blood tests might also be require. Please do not worry.
