What are the risk factors for laryngeal cancer?

In today's society, various diseases endanger human health. Diseases come like a mountain, and no matter whether they are successful or not, diseases treat everyone equally. Of course, with the continuous advancement of science and technology, there are more and more methods to treat laryngeal cancer, and the effect is getting better and better, but the harm caused by laryngeal cancer to humans should not be underestimated. Let's take a look at the harm of laryngeal cancer.

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 ipsilateral headache and ear pain. These symptoms mainly occur in patients with supraglottic tumors.

5. Precancerous lesions occur: Some laryngeal diseases such as laryngeal pachyderma, laryngeal leukoplakia, laryngeal papilloma, etc. may also turn into cancer. This is called precancerous lesions and must be followed up regularly to be on the safe side.

6. Difficulty breathing: This is a symptom of the later stage, indicating that the cancer has developed to the point of blocking the throat.

7. Cervical lymph node metastasis: This is one of the early symptoms of laryngeal cancer. It can metastasize to the deep middle cervical lymph nodes on the same side, and may metastasize to the opposite side in the late stage.

Generally, the early symptoms of laryngeal cancer are not very obvious, so many people ignore the common early symptoms of laryngeal cancer. Neck lumps, abnormal sensations in the throat, etc. are all early symptoms of laryngeal cancer. The following is a detailed introduction of the early symptoms of laryngeal cancer by experts.

Neck lump: The early symptoms of laryngeal cancer are often a lump in the upper neck behind the mandibular angle. Patients often do not have any obvious symptoms, but seek medical treatment for a lump in the neck. This type is mostly supraglottic laryngeal cancer, with no other obvious symptoms and metastasis early.
