Will there be no symptoms in the middle and late stages of lung cancer?

1. Patients with advanced small cell lung cancer may have some clinical symptoms, including cough, sputum, hemoptysis, blood in sputum, asthma, chest tightness, shortness of breath, chest pain, fever, dyspnea, dysphagia, hoarseness, etc., or some general systemic manifestations, including weight loss, loss of appetite, fatigue, fever, malignant diseases, etc., or metastasis, corresponding symptoms of metastatic sites, such as local tenderness, liver pain, hepatomegaly, jaundice, ascites, etc. in bone metastasis. There are very few asymptomatic patients.

2. Lung cancer in the middle and late stages indicates that the patient has lymph node and lung metastasis or remote metastasis. At this time, the patient will have more or less clinical symptoms. Some patients may mainly have lung symptoms, such as irritating dry cough, asthma, coughing up blood, coughing up sputum, and even dyspnea. If lung cancer has metastasized to the liver, when the metastasis is relatively small, the damage to the liver is relatively small, and the patient may not have symptoms of liver dysfunction.

Is chemotherapy effective for advanced lung cancer?

If the patient has a poor physical condition or genetic testing indicates that the lung cancer is effectively treated with targeted drugs, chemotherapy cannot be chosen and targeted therapy can be chosen. In advanced non-small cell lung cancer, targeted therapy is also mentioned as the first-line treatment, which is no less effective than chemotherapy and has much milder side effects than chemotherapy. Therefore, chemotherapy is still useful for advanced lung cancer, but we should choose according to the patient's physical condition.

For lung cancer patients, chemotherapy is still very effective in removing residual lesions after surgery, preventing recurrence, metastasis, killing and controlling tumors. Except for a few early-stage small cell lung cancers that can be removed surgically, the vast majority of small cell lung cancers are mainly treated with chemotherapy. Even in late-stage small cell lung cancers with extensive metastasis, the lesions may still regress significantly after chemotherapy.
