A 70-year-old lung cancer patient is himself a senior lung cancer patient and is at an advanced stage, which may not be amenable to surgical treatment. It is impossible to determine exactly how long a patient will live, because even without lung cancer, the exact life expectancy of a 70-year-old is uncertain. Patients with advanced lung cancer may not have a long survival time without effective treatment, which is usually in the range of 1-2 years. If a patient with advanced lung cancer cannot be treated with surgery but is suitable for targeted therapy, the survival time may be longer. For example, if a patient with lung cancer has genetic testing, and if targeted therapy, such as Trokai or Erythroxa, is effective in application, the survival time can be extended. Some patients with advanced lung cancer have a survival time of more than 5 years after targeted therapy, and the treatment effect is better. For patients with advanced lung cancer at the age of 70, they can only try to reduce the pain and prolong the survival treatment, and observe while treating.
