As soon as you eat, there is phlegm, which has no inevitable connection with cancer. It may be related to cancer, or it may not be related to cancer at all. Some patients with lung cancer may have cough, expectoration, chest tightness, and shortness of breath. The cough of lung cancer is often an irritant cough, and a small amount of white sputum or white mucus foam sputum can be coughed. If the secondary infection can cough purulent sputum, sputum often with blood or blood clots, can also be complete blood sputum. When a patient with lung cancer eats, it may stimulate the patient to cough with a small amount of sputum. Some benign diseases, such as chronic pharyngitis, may cough and discharge oral secretions when eating. Therefore, people with chronic pharyngitis should not eat too stimulating food, nor too salty or too sweet food to avoid stimulating phlegm.
