Tongue cancer is a type of oral cancer, with clinical symptoms primarily manifested in the following aspects. Many patients develop lumps on the tongue, which generally have unclear boundaries and easily adhere to surrounding tissues, showing limited mobility. The lumps exhibit persistent rapid growth, and when they invade nearby tissues, patients can experience ear pain and difficulties in tongue movement. In advanced stages, patients with tongue cancer may have a fixed tongue, drooling, difficulty eating, and unclear speech. Additionally, lumps in tongue cancer can undergo necrosis, ulceration, and secondary infections, bleeding, and some may have an abnormal taste. The disease can lead to lymph node metastasis, causing lymph node enlargement, often manifesting as neck lumps. Some patients may also experience metastasis to bone tissues, resulting in bone pain.
