The early symptoms of tongue cancer patients are mainly manifested as ulcerous lesions on the surface of the tongue, which relapse frequently. The effectiveness of common anti-inflammatory drugs and ulcer treatments is poor. The edges of these ulcerative lesions are rough and the bottom is unclean, often accompanied by abnormal secretions. When infected, the area may exhibit bleeding, pain, and other symptoms. Additionally, some early-stage patients may develop nodular lesions on the surface of the tongue. These nodules have irregular edges and tend to adhere to the surrounding tongue tissues. They are relatively hard, and their surfaces are prone to friction, bleeding, and even exhibit signs of inflammation such as redness and swelling.
