What are the early symptoms of tongue cancer?
Generally speaking, tongue cancer refers to cancer of the tongue. Early symptoms of tongue cancer include tongue ulcers, lumps on the tongue, tongue pain, numbness of the tongue, and bad breath. A detailed explanation is as follows:

1. Tongue Ulcers
In the early stages of tongue cancer, ulcers often appear on the tongue's mucous membrane and do not heal for a prolonged period, typically lasting more than two weeks. These ulcers are irregular in shape, with raised edges and a hard base, differing from common oral ulcers, which usually heal spontaneously within one to two weeks.
2. Lumps on the Tongue
Patients may feel painless lumps on their tongue. These lumps are usually hard and poorly defined at the borders. As the disease progresses, the lumps may gradually increase in size, affecting the normal movement of the tongue.
3. Tongue Pain
In the early stages, there may be only mild tongue pain, varying in intensity and possibly intermittent or persistent. This pain may worsen during eating or speaking and can easily be mistaken for oral inflammation or injury from biting.
4. Tongue Numbness
When the tumor invades the nerves of the tongue, it may cause abnormal sensations, leading to numbness. Patients may experience a reduced sense of taste and temperature in the tongue.
5. Oral Odor
The lesion of tongue cancer easily breeds bacteria, causing infection and possibly producing a distinctive oral odor. This odor differs from ordinary halitosis and is difficult to eliminate even through brushing teeth or rinsing the mouth.
In daily life, it is important to maintain good oral hygiene habits, such as brushing teeth correctly in the morning and evening, rinsing the mouth promptly after meals, and reducing bacterial growth in the oral cavity. Long-term harmful stimuli should also be avoided, such as quitting smoking, limiting alcohol consumption, avoiding very hot or hard foods, and minimizing injury to the tongue's mucous membrane.
