Anal canal polyp is actually anal papilla hypertrophy, is a benign occupying lesion in the intestinal lumen, cholesterol polyp is common, mostly asymptomatic, it is generally believed that the polyp is a predisposing factor for cancer carcinoma. The disease should be treated surgically and supplemented by non-surgical treatment. In normal human cells, there are two genes, K-RAS and G-RAS. Under normal circumstances, these two genes are in a relatively balanced state, and when the body’s resistance declines, the body’s immune cells are less able to monitor the two genes mentioned above, coupled with cholesterol metabolism abnormalities and other causative factors, there are gene mutations, which cause the cells of the gallbladder wall to undergo a kind of abnormal proliferation and grow into the lumen of the intestine. The growth of redundant organisms, i.e., anal canal polyps. What should patients with anal canal polyps eat? 1, porcini mushrooms: rich in selenium, with an increase in tissue immune function, promote the dissipation of inflammation, can reduce the incidence of this disease after surgery combined with bacterial disease infection. 150g and meat cooked with food. 2, Shiitake mushrooms: rich in selenium, cellulose, protein, amino acids, with the role of increasing tissue immune function, can reduce the incidence of post-surgical infectious inflammation. 150g and meat with stewed food. 3, fish skin: rich in collagen protein, has increased tissue immune function, especially to promote tissue repair, can reduce the healing time of the tissue after surgery. 100g stir-fry consumption.
