I have been coughing for more than a month and it hasn't gotten better. Is it lung cancer?

If you have a cough for more than a month and it doesn't get better, it may not be lung cancer. This may be caused by diseases such as chronic bronchitis and tuberculosis.

1. Lung cancer

1. Early stage: If the patient is not discovered and treated in time in the early stage of the disease, it may develop into lung cancer. At this time, the cancer cells will invade the surrounding tissues and organs, and will also metastasize through the lymphatic system and blood circulation, which will make the disease incurable to a certain extent.

2. Middle and late stages: If the patient's condition is serious and has reached the middle and late stages, cancer cells will spread and metastasize, thus affecting the normal quality of life.

2. Not lung cancer

1. Chronic bronchitis: Chronic bronchitis is a common respiratory disease, which may be related to factors such as long-term smoking and alcoholism. After the disease occurs, it is easy for patients to experience symptoms such as coughing and sputum. As the disease progresses, it will also affect normal diet. You can take levofloxacin hydrochloride tablets, amoxicillin capsules and other drugs as prescribed by the doctor.

2. Pulmonary tuberculosis: Pulmonary tuberculosis is caused by infection with Mycobacterium tuberculosis. It is contagious and can be transmitted through the respiratory tract, digestive tract, etc. After the disease occurs, it is easy for the patient to have symptoms such as low fever, night sweats, weight loss, and chest pain, hemoptysis, etc. Patients can take rifampicin capsules, pyrazinamide tablets and other drugs under the guidance of doctors.

It is recommended that patients go to the hospital for medical treatment in time and receive symptomatic treatment after the cause is identified. They should pay attention to rest, avoid overwork, and maintain a good attitude, which is conducive to physical recovery.
