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

Sputum and blood after recovering from a cold may be caused by lung cancer, or it may be caused by bronchitis, pneumonia and other diseases.

First, it is lung cancer

If a patient has lung cancer, the cancer cells will gradually spread to the lung tissues, affecting normal respiratory function. At this time, the mucous membrane of the respiratory tract will be irritated, and even symptoms such as coughing up sputum and blood in the sputum may occur. Once lung cancer is diagnosed, it needs to be treated by surgical resection of the lesion in time, and postoperative treatment by radiotherapy and chemotherapy is also required.

Second, it is not lung cancer

1. Bronchitis: Bronchitis refers to an inflammatory reaction that occurs in the bronchial part, which will cause severe cough at the onset of the disease, and is also accompanied by the symptoms of sputum production, and in severe cases, it will also cause blood in the sputum.It can be treated with drugs such as dextromethorphan hydrobromide granules and ambroxol hydrochloride oral solution as prescribed.

2. Pneumonia: Pneumonia is usually caused by bacterial or viral infection, which is easy to cause symptoms such as fever, chest pain, cough and sputum, and may cause blood in sputum with the development of the disease. If it is caused by a bacterial infection, you can take amoxicillin capsules, cefixime tablets and other drugs as prescribed for treatment. If it is caused by viral infection, you can take antiviral drugs such as ribavirin granules and oseltamivir phosphate granules according to the doctor's instructions.

In addition, it is not ruled out that it is caused by tuberculosis and other reasons, and it is recommended that patients seek medical examination and treatment in time.
