How long can a person with lung cancer live?

How long a person with lung cancer can live all depends on the stage at which lung cancer is discovered. Lung cancer has the potential to be cured when caught early.

How long a person with lung cancer can live depends on the type of lung cancer, age, comorbidities (the presence of other diseases) and staging. The chances of survival decrease if the cancer has spread to any other organs or lymph nodes. That said, every survival rate is determined on a case-by-case basis.

The length of time a person can live depends on what stage of cancer is in when diagnosed, how well the cancer responds to therapy and what mutations the cancer cells have. 
  • Stage 1: The cancer is small and limited to the lung. It can be treated with either surgery or radiation therapy alone. These patients have the best chance for cure and survival.
  • Stage 2: The cancer is either larger, has grown into the chest wall, or has spread to local lymph nodes. Multiple different types of treatment are required, including chemotherapy, radiation therapy, and surgical resection. Survival in this stage is worse than that seen for patients in stage 1.
  • Stage 3: The cancer has spread to regional lymph nodes and tumors may have grown into other organs. Multiple types of treatments are required. For some patients, surgical removal of tumors is no longer an option. Survival in this stage is worse than that seen for patients in stage 2.
  • Stage 4: Cancer has spread to other parts of the body. Patients do not typically have a chance at long-term cure with surgery. They typically undergo chemotherapy and are occasionally treated with radiation to help with their symptoms. The chance of long-term survival is worst in this stage of lung cancer.

The answer to this question depends on the stage of the lung cancer.  If the lung cancer is diagnosed in an early stage, this is potentially a curative disease and can be often cured with surgery or radiation or chemotherapy.  However, if the lung cancer is diagnosed with late stage, this is not usually a curative disease and the life expectancy depends on multiple factors.  A lot of that depends on the stage of the disease, the site of metastases, the performance status of the patient, in other words, how good general health the person is, and the nature of the lung cancer.  In short, there is no one answer to this question.   We now know that we can identify a separate group of patients with variable types of lung cancer and their survival rates are different.  In conclusion, I would like to say that every person with lung cancer is different and their survival depends on multiple factors.
