Introduction

Under normal circumstances, lung adenocarcinoma is not contagious. This disease is primarily associated with factors such as viral infections, genetics, and smoking, none of which are contagious. However, if there is a family history of lung adenocarcinoma, the risk of developing the disease is higher among offspring. Therefore, regular medical check-ups at a hospital are recommended. If precancerous lesions or other abnormalities are detected, prompt medical intervention is advised.

Generally speaking, lung adenocarcinoma refers to adenocarcinoma of the lung. Lung adenocarcinoma is not contagious. If experiencing any discomfort, timely medical consultation is recommended. Detailed explanation is as follows:

Lung adenocarcinoma is a type of malignant tumor that develops from malignant transformation of lung epithelial cells, usually associated with factors such as viral infections, genetic predisposition, long-term smoking, and exposure to secondhand smoke. None of these causes are contagious and cannot be transmitted directly or indirectly through contact. Therefore, lung adenocarcinoma is not transmissible.

However, lung adenocarcinoma is difficult to treat and prompt treatment is necessary after diagnosis. If diagnosed at an early stage, lobectomy under medical guidance is recommended. This treatment involves surgically removing the affected lobe of the lung containing the cancerous tissue to achieve therapeutic purposes. For locally advanced or metastatic disease, surgical treatment may be less effective; therefore, it is recommended to follow medical advice and use medications such as carboplatin injection, cisplatin injection, and paclitaxel injection for treatment.

Although lung adenocarcinoma itself is not contagious, individuals with a family history of lung adenocarcinoma may have a higher risk of developing the disease. Therefore, regular physical examinations are recommended to monitor health status promptly.

What is the survival period for targeted therapy in lung adenocarcinoma?

The survival period for targeted therapy in lung adenocarcinoma is approximately 1 to 5 years, and the actual survival period may vary due to individual differences.
