At the age of 70 with advanced lung cancer, if it is advanced small cell lung cancer, the treatment effect is relatively poor, and the survival time of patients can reach about 1 year through systematic treatment is a relatively ideal treatment effect. In recent years, with the rise of targeted therapy, the survival time of patients with advanced non-small cell lung cancer, especially adenocarcinoma, has been relatively prolonged, and it can be prolonged for 2 years or even longer. There is no definite answer to the question of how long can one live with advanced lung cancer, different patients will have different results, and the survival time ranges from a few months to a few years, depending on the extent of spread of lung cancer, as well as the patient’s response to the disease, the patient’s age, state of mind, whether there is any metastasis of the cancer’s pathologic classification, and the surgery, etc. As long as the metastasis is successfully controlled, the patient can have a very long survival period.
