The survival time of patients with invasive lung adenocarcinoma is related to the size and location of the tumor, the presence or absence of distant metastases, and the treatment method, and cannot be generalized. Invasive lung adenocarcinoma is mainly a malignant tumor caused by cancer cells infiltrating into the tissues surrounding the lungs. Patients usually experience breathing difficulties, physical fatigue and weakness, yellowing face and cough. If the tumor can be radically removed surgically, the 5-year survival rate can reach more than 60%-70% with radiotherapy and chemotherapy after surgery. However, for some lung cancers that have metastasis or patients with poor heart and lung function and cannot tolerate surgery once they are found, most of the lung adenocarcinoma that cannot be surgically removed may have a survival period of less than 3-5 years, but if genetic testing is done and they can be treated with targeted drugs, such as Erythropoietin and Troche, the survival period will be greatly extended. In addition, patients with invasive lung cancer should eat more fresh vegetables and fruits after surgery, which can effectively increase body immunity, try to avoid stimulating foods, avoid shrimp, crab and other foods that can cause allergy, and quit smoking and alcohol.
