How long can you live if lung cancer recurs

How long can you live if lung cancer recurs?

1. If the lung cancer is an adenocarcinoma, since we currently have many new drugs in clinical practice, including good chemotherapy drugs and targeted therapy drugs, patients with adenocarcinoma can maintain tumor shrinkage or non-progression for a long time through treatment, and patients can survive for a considerable period of time.

2. If the patient's pathology is non-small cell lung cancer, targeted drug therapy can be considered, but before taking targeted drug therapy, a targeted drug test is required, and it is only recommended when mutations occur. Lung cancer is a malignant tumor with a relatively high degree of malignancy. After surgery, lung cancer patients often relapse, and this recurrence is more common in patients with advanced lung cancer.

Is a high-density shadow in the lungs on CT scan a precursor to lung cancer?

High-density shadows in the lungs are an imaging description and are not necessarily a precursor to lung cancer. It mainly depends on the comprehensive analysis results of the CT report. In particular, high-density shadows in the upper lobes of the lungs are likely to be congenital or calcifications left by tuberculosis.

The density of lung nodules cannot completely determine whether they are benign or malignant. Among patients with high-density nodules accompanied by calcification, 55% have benign nodules, but 13% of lung cancers also have high-density calcification, such as carcinoid, metastatic osteosarcoma, chondrosarcoma, etc. High-density ground-glass opacities in the lungs are not necessarily lung cancer.
