Choroidal tubular adenoma may become cancerous after resection. Because it contains a villous component, it is a progressive adenoma. Because it has a certain rate of malignant transformation, it should be removed endoscopically as soon as it is detected and should be followed up regularly. After resection of villous ductal adenoma, studies have reported that the risk of colorectal cancer in progressive adenocarcinoma is twice that of non-progressive adenoma after resection and three times that of adenoma-free adenoma. However, if the disease is not treated promptly, it is likely that the choroidal tubular adenoma will persistently increase in size and may then become cancerous. Therefore, patients with choroidal adenoma should be treated promptly, such as by surgical removal. Postoperative treatment and care are also important. After surgery, patients should take rest and eat a light diet that is nutritious and easy to digest, such as millet porridge, noodles, milk, eggs, etc., to reduce the stimulation of the intestinal tract. Pay attention to rest and avoid staying up late, as well as regular postoperative review.
