What are the differences between esophageal cancer and laryngeal cancer

What is the difference between laryngeal cancer and esophageal cancer? Nowadays, many cancer diseases continue to trouble people and make people very upset. The following is an introduction to the difference between laryngeal cancer and esophageal cancer. What is laryngeal cancer like? Let's learn about it together. I hope it will be helpful to everyone.

The incidence of laryngeal cancer accounts for 8% of all malignant tumors in the body, ranking third in the field of otolaryngology, after nasopharyngeal cancer and nasal and paranasal sinus cancer. The most common age group is 50 to 70 years old. The highest incidence rate is in the northeast of my country, and most of the patients are men. The cause of the disease is not yet clear, but the air pollution in cities with heavy pollution is higher than that in cities with light pollution.

There are differences in the symptoms between laryngeal cancer and esophageal cancer, and patients should correctly identify them. In the early stages of esophageal cancer, patients often experience dysphagia, accompanied by intermittent pain, dryness and tightness in the throat, and a sense of oppression, distension, and belching behind the sternum. The dysphagia of esophageal cancer is a transitional process. Usually, it is difficult to swallow solid food first, then semi-solid food, liquid food, and finally even no one can swallow it. Its symptoms are much more serious than pharyngitis, and the consequences are disastrous.

Symptoms of throat cancer include:

1. Hoarseness: It is the earliest symptom of vocal cord cancer, which is usually persistent and gradually worsens. The early symptoms of subglottic cancer are not obvious, while hoarseness is a symptom of the later stage.

(ii) Coughing and coughing up blood: Coughing is mostly irritating and dry, and when there is sputum, there is blood in the sputum. When the tumor grows, it will make the secretions in the trachea difficult to discharge, often causing respiratory infections. It is a more serious symptom among the early symptoms of laryngeal cancer and should be diagnosed and treated in time.

(III) Abnormal sensation in the throat: foreign body sensation, urgency or swallowing discomfort in the throat are symptoms of early laryngeal cancer. The early symptoms of this type of disease are not obvious, and because the lesions are relatively hidden, they are often difficult to detect. Therefore, middle-aged and older patients with throat discomfort should undergo a comprehensive and detailed examination, and should not be hastily treated as pharyngeal paresthesia or chronic pharyngitis, which may lead to misdiagnosis.

(IV) Neck lumps: lumps often appear behind the mandibular angle in the upper neck. Most patients have no obvious symptoms and seek medical attention for lumps in the neck. This type is mostly supraglottic laryngeal cancer, with no other obvious symptoms and early metastasis.

The above is an introduction to the relevant content. I hope it will be helpful to patients and friends.
