There is no inevitable relationship between flaking moss and cancer. In Chinese medicine, flaking moss is more commonly talked about because Chinese medicine looks more at the pulse and tongue. In TCM, it is mainly considered that there is internal heat of yin deficiency, and this internal heat is often accompanied by dampness, that is, dampness-heat and injury to yin. This condition is mainly a problem of the spleen and stomach in Chinese medicine. Generally, the spleen and stomach are used to remove dampness and nourish yin, and the symptoms may be relieved after the dampness and heat are removed. In modern medicine, the flaking moss is not considered to be related to cancer. On the one hand, it may be mainly due to the reaction of poor immunity, on the other hand, there is often the growth of mold and bacteria in the mouth, as well as certain problems in the function of the intestines and stomach, which may have flaking moss. If you are worried about cancer, you should focus on investigating tumors in the digestive tract.
