Tubular adenoma 0.8cm has a very small chance of recurrence after surgery, which needs to be judged according to the size of the adenoma, the amount of chorionic tissue and gender habits. 1. Size of adenoma: most foreign scholars think that adenomatous polyps with diameter ≥10mm are easy to become cancerous, and the cancer rate of polyps increases with the increase of diameter. Therefore, adenomas with a diameter of 8mm are smaller in size and have a lower chance of recurrence. 2. How much chorionic tissue is there: the proportion of chorionic component of tubular adenomas in neoplastic adenomas is the smallest, less than 25%, while tubular chorionic glands and chorionic adenomas account for a larger proportion. Research shows that choriocapillaris may have the characteristics of tissue cell division and faster growth rate, and choriocapillaris may have malignant changes in the process of growth, and even develops into heterogeneous hyperplasia which is not regulated by the organism, so its malignant rate may be higher than that of tubular tissue, and it is easy to be recurred as well. 3. Gender and life habits: men have more bad life habits such as smoking and drinking, etc., while the content of estrogen and progesterone in women’s body is much higher than men’s, which can play a certain anticancer role, and also have a certain role in reducing the recurrence rate of intestinal polyps in patients. Therefore, when diagnosed with tubular adenoma, don’t worry, the probability of recurrence is very small after active treatment, and regular review can be done according to the doctor’s instructions.
