Is it lung cancer if there is blood in sputum after recovering from a cold?

Blood in sputum after recovering from a cold may be caused by lung cancer, or it may be caused by other diseases such as bronchitis and pneumonia.

1. Lung cancer

If a patient has lung cancer, cancer cells will gradually spread to the lung tissue, thus affecting normal respiratory function. This will cause irritation of the respiratory mucosa, and even symptoms such as coughing, expectoration, and blood in the sputum. Once lung cancer is diagnosed, surgery to remove the lesion is necessary, and radiotherapy and chemotherapy are also needed to assist in improvement after surgery.

2. Not lung cancer

1. Bronchitis: Bronchitis refers to an inflammatory reaction that occurs in the bronchial area. When it occurs, there will be severe coughing and sputum. In severe cases, it will cause blood in the sputum. You can follow the doctor's advice and use drugs such as dextromethorphan hydrobromide granules and ambroxol hydrochloride oral solution for treatment.

2. Pneumonia: Pneumonia is usually caused by bacterial or viral infection. After the disease occurs, it is easy to cause symptoms such as fever, chest pain, cough and sputum. As the disease progresses, it may also cause blood in the sputum. If it is caused by bacterial infection, you can take amoxicillin capsules, cefixime tablets and other drugs for treatment as prescribed by the doctor. If it is caused by viral infection, you can take ribavirin granules, oseltamivir phosphate granules and other antiviral drugs for treatment as prescribed by the doctor.

In addition, tuberculosis and other causes cannot be ruled out. Patients are advised to seek medical examination and treatment in time.
