Lung cancer occurs when the tissue cells in the lungs lose their normal genetic regulation, mutations occur in the genes, and normal tissue cells grow disorderly, forming a disease characterized mainly by tumors, known as lung cancer. The clinical manifestations of lung cancer can include choking cough, cough, coughing up blood, fever, weight loss, and other symptoms. However, it does not necessarily mean that a choking cough is definitely lung cancer. For example, conditions like bronchitis, asthma, chronic obstructive pulmonary disease, and even pneumonia and lung infections can cause choking coughs. Some colds may also present symptoms of choking cough. Therefore, a choking cough is not necessarily indicative of lung cancer. It is essential to consider the patient's age, occupation, smoking history, and if available, to combine this information with chest X-rays to make a comprehensive determination of whether it is lung cancer.
