Lung cancer is one of the most common malignant tumors and has the highest mortality rate among cancers. The question of how long one can live with lung cancer depends on the pathological type of cancer, tumor stage, patient’s age, basic physical condition and whether one can receive timely and reasonable treatment. Generally speaking, there are two types of lung cancer: small cell lung cancer and non-small cell lung cancer, which are discussed separately. Non-small cell lung cancer: common adenocarcinoma, squamous carcinoma, alveolar carcinoma, etc. Early stage (mostly stage I) 5-year survival rate after radical surgery is about 45%, in other words: 45% of early stage lung cancer patients can live past 5 years after surgery; early and middle stage (mostly stage II) 5-year survival rate after radical surgery is about 30%. The average survival of late stage is 11.5 months. Small cell lung cancer: high malignancy and rapid disease progression, average survival of 12-18 months in limited stage, and 6-10 months in extensive stage. Once diagnosed with “advanced lung cancer”, many patients are in infinite panic and feel that death is coming. In the treatment of lung cancer, only 15% of lung cancer patients can be treated by surgery to remove cancer cells; about 5% of lung cancer patients cannot be operated due to the limitation of tumor growth site; and more than 70% of lung cancer patients cannot be treated by surgery due to the lack of timely detection of the disease. If not treated in time, the survival time of stage IV lung cancer patients is about 3-6 months. In fact, there is no general rule on how long a patient with advanced lung cancer can live. As long as patients with advanced lung cancer are actively treated, they can also extend their survival period. Lung cancer is mainly divided into non-small cell lung cancer and small cell lung cancer. The survival rate of non-small cell lung cancer patients five years after surgery is 44.5% for stage I, 36.1% for stage II, and less than 30% for stage IIIA. For early stage small cell lung cancer patients, if surgery is combined with biologic therapy and radiotherapy, the survival rate can reach 65% in three years and 50% in five years without lymphatic metastasis. However, if lymphatic metastasis of lung cancer is present, the survival rate of patients will be reduced by 15-30 percentage points. Special symptoms of late stage lung cancer: Lung cancer, also known as bronchial lung cancer, is called the cancer of cancers. Since the industrial era, the incidence rate and death rate of lung cancer have been increasing year by year at an alarming rate. For patients with advanced lung cancer, their symptoms are very obvious, including lumps, pain, shortness of breath, coughing up blood, fever, etc. Patients are often suffering from unimaginable pain. If you find that the patient suddenly loses speech, changes color, or stops breathing, you must immediately report to the doctor for emergency resuscitation.
