Esophageal cancer and laryngeal cancer are both malignant tumors. Esophageal cancer refers to the malignant tumor occurring in the esophagus, while laryngeal cancer refers to the malignant tumor occurring in the larynx. Therefore, their tumor locations are different. The pathology of both is generally squamous cell carcinoma. The main symptom of esophageal cancer is obstructed eating; patients will feel difficulty swallowing, obstruction, and worsening of these symptoms as they eat. The primary symptom of laryngeal cancer is typically a hoarse voice, which distinguishes the symptoms of the two cancers.

Where is throat cancer likely to metastasize?

The metastasis of laryngeal cancer primarily involves local spread, mainly to the lymph nodes in zones 2, 3, and 4 of the neck. When the cancer becomes more severe, it can break through the lymphatic vessels and spread to the liver, kidneys, spleen, brain, lungs, and other related areas. Laryngeal cancer is a malignant tumor of the pharyngeal region, typically caused by long-term smoking, drinking, immunodeficiency, and cellular mutations. It commonly occurs in the vocal cords, esophagus, laryngeal ventricle, piriform sinus, base of the tongue, and epiglottis. It causes patients to feel a foreign body sensation in the throat, persistent hoarseness that progressively worsens, irritative cough, difficulty swallowing, and difficulty breathing. An examination with an electronic laryngoscope can help diagnose the condition. If an abnormal mass is found, a local biopsy is necessary. If laryngeal cancer is confirmed, related surgical treatment as well as radiotherapy or chemotherapy may be required.

Precursors of throat cancer

Nasopharyngeal cancer, located behind the nasal cavity and above the oropharynx, is generally difficult to diagnose early due to its concealed location. However, there are early signs, such as nasopharyngeal bloodstained mucus experienced during sniffing, which should raise suspicions of nasopharyngeal cancer. Additionally, early-stage nasopharyngeal cancer may present with unilateral nasal obstruction, which gradually progresses to more severe blockage. Another indication is the presence of a neck lump or enlarged lymph nodes, which also suggests the possibility of nasopharyngeal cancer. Other nonspecific reactions, such as dermatitis, dermatomyositis, or a general skin rash, should also be considered potential indicators of nasopharyngeal cancer. These signs require attention.

Can throat cancer be contagious?

Laryngeal cancer is not contagious. Current medical evidence and research indicate that laryngeal cancer does not have a definitive contagious nature. There are many factors involved in the onset of laryngeal cancer, and clinically, the possible inducing factors have not been completely determined yet. These factors may include having a family history, or frequent exposure to radioactive or chemical substances, as well as potentially due to long-term smoking and drinking, which are risk factors that could lead to the disease. Overall, the exact cause of the disease is not particularly clear, but regardless of the factor, no contagious nature has been found. Therefore, laryngeal cancer is not infectious and is not considered a communicable disease. In terms of treatment, surgery is primarily considered, and some cases may also require consideration of radiotherapy or chemotherapy. Generally, it is regarded as a relatively common malignant tumor of the head and neck.

Will throat cancer recur after surgery?

After undergoing surgical treatment for throat cancer, it is important to pay attention to your diet, arrange your daily routine reasonably, maintain a cheerful mood, and have regular follow-up exams as directed by your doctor. Generally, there is a possibility of recurrence within five years. It is recommended to consume some traditional Chinese medicines that have good anti-tumor effects to prevent the recurrence of the disease. Additionally, change your physical constitution and enhance your body's immunity.
