Jagged tongue is not stomach cancer.
Early stage of stomach cancer patients usually have no obvious symptoms, and a small part of them may have bloating, early satiety, indigestion, etc. In the late stage of stomach cancer, they may have vomiting blood, abdominal pain, abdominal mass, black stools, anorexia, etc., which are usually not accompanied by tongue changes.
Causes of jagged tongue include lymphatic malformation of tongue, ulcer of tongue, hemangioma, enlarged tongue caused by leukoplakia of mucous membrane of tongue, and it may also be caused by extrusion of teeth or partial loss of teeth in the mouth, which leads to outward growth of tongue and physiological enlargement of tongue, resulting in jagged tongue. Therefore, jagged tongue is not directly related to stomach cancer.
It is suggested that if tongue shows jagged shape, one should go to stomatology department of regular hospital for early diagnosis and treatment. Usually, you should eat less spicy and stimulating things, eat more fresh vegetables and fruits, develop a good habit of rest and relaxation, and keep a happy mood.
