How to diagnose lung cancer? Cough and hematemesis, if not tuberculosis, can it be lung cancer?

Hello! We can't judge your situation until further examination. The diagnosis of lung cancer is mainly through radiological examination, as follows:

1. No symptoms or signs. If X-ray chest film finds isolated nodules or masses in the lung, which are lobulated or have fine burrs, or CT examination proves that there are signs of bronchial obstruction, it should be suspected as lung cancer.

2. Long-term smoking male, over 40 years old, accompanied by irritating cough, intermittent or persistent hemoptysis, chest X-ray showed localized lung lesions, which were ineffective after active anti-inflammatory or anti-tuberculosis treatment (2-4 weeks) or enlarged lesions.

3. Segmental pneumonia develops into atelectasis within 2~3 months, or atelectasis develops into total atelectasis in a short time, or a lump appears at the root of atelectasis, especially a growing lump.

4. There is no other reason for the increase of pleural effusion on one side in a short time, or a large amount of bloody pleural effusion with atelectasis on one side needs to be verified by bronchoscopy.

5. Obvious shortness of breath, cough, miliary or diffuse lesions on both sides of X-ray chest film, miliary tuberculosis, lung metastatic cancer, pulmonary mycosis and other lesions should be excluded.

6. Lung is found in the chest, accompanied by hilar or/and mediastinal lymph node enlargement, and neurovascular compression symptoms such as superior vena cava obstruction and recurrent laryngeal nerve paralysis, or accompanied by distant lymph node metastasis.

7. Cytological examination or biopsy confirmed the diagnosis.

Lung cancer patients with headache, nausea or other nervous system symptoms and signs should consider the possibility of brain metastasis. Bone pain, blood alkaline phosphatase or elevated blood calcium should consider the possibility of bone metastasis. If the right epigastric pain, swelling, alkaline phosphatase, aspartate aminotransferase, lactate dehydrogenase or bilirubin increase, the possibility of metastasis should be considered. Nodules can be touched under the skin during subcutaneous metastasis; When blood is transferred to other organs, you can see the symptoms of the corresponding transferred organs. If auxiliary therapeutic drugs such as ginsenoside Rh2 (life-saving factor) can be used in combination with routine treatment, the disease can be stabilized and the tumor can be reduced.
