Throat cancer is a malignant tumor that occurs in the throat area. Its causes are not clear, but it is generally associated with long-term smoking, drinking, exposure to toxic and carcinogenic substances, as well as gastrointestinal dysfunction, acid reflux irritation, prolonged loud speaking, staying up late, fatigue, and malignant transformation of benign tumors, which lead to symptoms in the throat area. It causes persistent hoarseness in patients, and the symptoms progressively worsen. Patients may also experience a foreign body sensation in the throat, a feeling of blockage, a burning sensation, and sometimes difficulty swallowing. Patients should first go to the hospital for a detailed examination with an electronic laryngoscope, which can reveal cauliflower-like neoplasms or ulcers in any part of the throat. If such findings are present, a local biopsy is needed. If the biopsy confirms the presence of a malignant tumor, local surgery, radiotherapy, or chemotherapy is required for treatment.
