Blue tongue

Although cancer patients often have bruising tongues, not all people with bruising tongues have cancer. Other chronic diseases such as coronary heart disease, pulmonary heart disease, chronic liver disease, diabetes, vasculitis, Lupus erythematosus, women's dysmenorrhea, amenorrhea, etc. can also be seen with bruising tongue, but the proportion and severity are far less than cancer. Once the blue-tongue tongue is found, a doctor should be examined in detail to find out the cause and treat it promptly. Don't neglect paralysis.
