Can early lung cancer be detected by CT?

For example, the diagnosis of lung cancer should be based on symptoms and signs, sputum cytology, CT, MRI, bronchoscopy, pathological histology, lung puncture biopsy and tumor markers. Generally, small nodules with a diameter of less than 2 mm can be clearly displayed by CT scan. If you want to make a specific diagnosis of the lesion, you need to combine it with pathological examination. CT can detect space-occupying lesions, and pathological tissue biopsy is required to confirm lung cancer.

Is chemotherapy necessary after surgery for early stage lung cancer?

In most cases, patients with early-stage lung cancer can achieve clinical cure through radical surgery, while some lung cancer patients need adjuvant chemotherapy after surgery to control existing subclinical lesions, thereby reducing the risk of recurrence of lung cancer after surgery. If the pathological staging after lung cancer surgery is found to be a very early stage, such as t1n0m0, no postoperative adjuvant therapy is required. Lung cancer is a malignant tumor of the lungs. Generally speaking, chemotherapy is not required for consolidation treatment in the early stages.

Why does lung cancer cause vomiting after eating?

Even patients with liver metastasis of lung cancer may experience vomiting. Active treatment of the primary disease is needed. For liver metastasis, radiotherapy can be considered to shrink the tumor. If the examination confirms brain metastasis, mannitol should be used to reduce intracranial pressure and drugs should be used for symptomatic treatment. There are two possible causes of loss of appetite in late-stage lung cancer: one is vomiting after chemotherapy.
