Lung cancer includes adenocarcinoma of the lung, also known as adenocarcinoma of the lung, which is the most common type of lung cancer. Lung cancer can be divided into small cell carcinoma and non-small cell carcinoma, and adenocarcinoma of the lung belongs to non-small cell carcinoma. It can occur in the central airways and small bronchi, and commonly can grow outside the airways and spread with the alveoli to form nodules or masses. Lung cancer, on the other hand, covers a wide range and can occur anywhere in the lungs. Adenocarcinoma of the lung is more common in women and is slow-growing, with some metastasizing in the early stages and a 5-year survival rate of less than 10% after surgical resection. Patients with lung adenocarcinoma may include lesion types such as fine bronchoalveolar carcinoma, microinvasive adenocarcinoma, invasive adenocarcinoma, and invasive adenocarcinoma variant. The treatment for lung adenocarcinoma is usually chosen to be treated by surgical resection or, if some patients are not suitable for surgical treatment, radiation therapy, etc. Lung cancer includes a wide range, such as small cell carcinoma and non-small cell carcinoma, and non-small cell carcinoma may include squamous carcinoma, adenocarcinoma, large cell carcinoma, etc. Clinically, patients can generally choose conservative treatment, surgical treatment, minimally invasive surgical treatment, etc. for treatment according to their specific conditions. Both lung cancer patients and lung adenocarcinoma patients should follow the principle of early diagnosis and early treatment, and actively receive lung cancer treatment. Attention should be paid to avoid smoking and environments with more dust or harmful gases as much as possible.
