Cracked tongue is not a precursor to cancer.
1. Cracked tongue may be caused by chronic diseases such as gastroenteritis, cholecystitis, diabetes, hepatitis or tuberculosis. These chronic diseases will gradually affect the digestive system, leading to impaired nutrient absorption and relaxation of the tongue mucosa, thus leading to tongue cracks.
2. In addition, due to the decline in body functions of elderly patients, the tongue’s ability to absorb nutrients decreases, leading to metabolic disorders, and cracks or grooves will occur in the middle of the tongue. In some cases, it is a congenital genetic factor and does not require special treatment if there are no obvious discomfort symptoms.
Cracked tongue is not a precursor of cancer; there are many precursors of cancer. If deep cracks with ulcers appear on the tongue, as well as obvious and severe pain that does not subside for more than three weeks, it is recommended to go to a regular hospital for examination. If necessary, a local biopsy may be performed to confirm the diagnosis.
