What causes the symptoms of throat cancer

What is laryngeal cancer? Laryngeal cancer is a general term for nasopharyngeal cancer, oropharyngeal cancer, and laryngeal cancer. It is a malignant tumor that occurs in the rhinitis, oropharynx, and larynx.

Throat cancer risk

1. Persistent hoarseness: Laryngeal cancer often affects the vocal cords. Even if the size is small, it can cause the patient to have hoarseness. Hoarseness is the earliest sign of laryngeal cancer. Adults who have unexplained hoarseness that lasts for more than two weeks should undergo a detailed laryngeal examination and should not take it lightly.

2. Abnormal sensation in the throat: foreign body sensation, urgency or swallowing discomfort are early symptoms of supraglottic laryngeal cancer. However, the initial symptoms of this type of cancer are often not obvious and are not discovered until the second or third stage. Therefore, if middle-aged and elderly people have throat discomfort, they should undergo a comprehensive and detailed examination.

3. Coughing with blood in sputum: Tumor stimulation may cause irritating dry cough with blood in sputum, and patients often feel sticky mucus. When the tumor grows, it will block the airway, making it difficult for tracheal secretions to be discharged, causing respiratory infections, wheezing, and even dyspnea. In the middle and late stages, it will manifest as persistent coughing and changes in pronunciation.

4. Reflex pain: When laryngeal cancer is combined with ulcers, inflammation or laryngeal cartilage periostitis, it can cause reflex pain in the nerves, manifested as headache and ear pain on the same side. These symptoms mainly occur in patients with supraglottic tumors.
