If spicy tongue is a cancer signal, it may be tongue cancer, but there are many symptoms of tongue cancer, and spicy tongue is not one of the typical symptoms, you can’t be sure that it is cancer by this point, but only the possibility exists, and you can further judge it according to the typical symptoms of tongue cancer, and it is better to go to the hospital to further confirm the diagnosis. If the patient has no ulcerated surface of oral mucosa, just a subjective feeling, it is more likely to be burning mouth syndrome. This disease is generally closely related to mental factors, so there is no obvious lesions in the body, patients can distinguish on this basis whether the tongue is hot with burning mouth syndrome. If there is redness and swelling of the papillae of the tongue in addition to the hotness of the tongue, then lobular papillitis can be considered.
