How to tell if you have lung cancer? What to do if you have lung cancer?

Whether you have lung cancer can be determined through imaging examinations, tumor marker examinations, pathological examinations, etc. If you get lung cancer, you can take surgical treatment, radiotherapy, chemotherapy, targeted therapy and other related treatment measures.

1. Methods to determine whether you have lung cancer

1. Imaging examination

Imaging tests, including chest X-rays, CT scans, MRI, etc., can help doctors observe and evaluate lung lesions.

2. Tumor marker examination

Tumor marker examinations include carcinoembryonic antigen, neurospecific enolase, cytokeratin 19 fragment antigen, squamous cell carcinoma antigen, etc. Through related joint examinations, they have certain reference value for the diagnosis of lung cancer.

3. Pathological examination

Lung tissue samples are obtained through biopsy or surgical resection, and pathological examination can determine whether it is lung cancer.

2. Treatment

1. Surgical treatment

Once lung cancer is diagnosed, it is recommended to perform surgical resection as soon as possible, including local resection, extended resection, etc., provided that the surgical indications are met.

2. Radiotherapy and chemotherapy

Radiotherapy and chemotherapy can be used after surgery to kill remaining cancer cells, thereby improving the efficacy. Among them, commonly used chemotherapy drugs include gemcitabine, cisplatin, etoposide, etc., which need to be used under the guidance of a doctor.

3. Targeted therapy

Targeted therapy inhibits tumor growth and spread by targeting specific cancer-related genes or proteins. Commonly used drugs include bevacizumab, gefitinib, etc., and they must be used according to medical advice.
