Is coughing in late stage esophageal cancer contagious?

Although esophageal cancer is a common and extremely harmful cancer, it is not transmitted through saliva, diet, air, and daily life. So, is the cough of esophageal cancer in the late stage contagious? Although esophageal cancer is a highly malignant disease, its probability of transmission is almost zero. Esophageal cancer can cause swallowing obstruction and pain behind the sternum, often causing severe malnutrition, cachexia, and heavy psychological burden in patients. Therefore, while receiving conventional treatment, it is necessary to pay attention to the patient's psychological activities and provide overall care.

(1) Smoking: In some areas where esophageal cancer is most common, the smoking rate is quite high, while in other areas where residents do not smoke, esophageal cancer is rare. This is because cigarettes contain several types of nitrosamines, which have strong carcinogenic effects.

(2) Eating habits: Long-term smoking and drinking of strong alcohol, long-term consumption of hot food, and eating hard food without chewing it thoroughly are all related to the occurrence of esophageal cancer.

(3) Nitrosamine compounds and fungal toxins: A survey in my country found that the content of nitrates, nitrites and secondary amines in food and drinking water in high-incidence areas has increased significantly. These substances can synthesize nitrosamines in the stomach. Various moldy foods can also produce carcinogens.

(4) Malnutrition and trace element deficiency: People who do not consume enough animal protein and lack vitamins A, B2, E, and C, lack trace elements such as molybdenum, zinc, magnesium, manganese, cobalt, and iron, as well as lack fresh fruits and vegetables are prone to esophageal cancer.

(5) Genetic factors: Patients in high-incidence areas of esophageal cancer have a positive family history of 27% to 61%; the peripheral lymphocyte chromosome aberration rate in the patient's family is relatively high. It can be seen that genetic factors play a certain role in the occurrence of esophageal cancer.

(6) Other esophageal diseases: Some common esophageal diseases, such as esophagitis and leukoplakia of the esophageal mucosa, may increase the incidence of esophageal cancer if not treated in time. Therefore, reducing the irritation of the esophageal mucosa can effectively prevent this disease.

Through the above introduction, I believe everyone has a certain understanding of it. If your health has symptoms of illness, do not delay diagnosis, and go to a regular hospital for treatment in time to avoid delaying the disease and causing serious consequences.
