What is the survival rate with lung cancer? How long can you live if you have lung cancer? What is the best case scenario?

Depends on stage. Survival for lung cancer is stage specific. Early stage has better survivalmthen late stage. However if you are being treated for lung cancer, the important thing is to stay positive and optimistic, regardless of the stage.
The statistics for. Survival speak to groups with similar factors...For an individual, the outcome is unique. I agree with the other answers as to data, especially the poor outcome with expected survival shorter than a year when disease is outside the chest (brain, liver, bones, etc). If you do not have lung ca, the best choice is to never smoke. Surgery best in nsclc; chemo for sclc. Radiotherapy key roles in each.
Cure is Possible. The chance of cure depends on the type of lung cancer and the stage at which it is diagnosed. Stage i tumors can sometimes be cured quite easily. Stage IV disease in which the tumor has spread to other organs is almost never cured. Talk to your doctor.
Depends. Survival rate: depends on the stage best case scenario: 100% cure which can occur in some lung cancers. For more on lung cancers, you can read: http://www.Cancer.Net/cancer-types/lung-cancer.
Survival . Survival after the diagnosis of lung cancer is a highly variable length of time. This is because there are different types of lung cancer, generally divided into non-small cell lung cancer (most common) and small cell lung cancer, both of which have differing prognoses. Furthermore, the location of the cancer and types of therapy given also affect the length of survival. By far the most important factor that determines survival is the stage (or spread of the lung cancer) at the time of diagnosis. Unfortunately, the majority of lung cancers are not diagnosed until the cancer has already spread to other structures in the chest (stage iii disease) and sometimes even to distant parts of the body (stage iv). To highlight the variability in survival with stage of non-small cell lung cancer, the median survival of patients with stage iiia disease is 14 months, whereas median survival with stage IV disease is 6 months. It is important to note that "median survival" is not an absolute time limit for survival, but rather a way of expressing a time that represents what we expect a half of patients with that stage of disease to live to. Some patients will unfortunately live considerably less, but by definition, some will also live longer. The "best case scenario" for patients with lung cancer clearly applies to patients with non-small cell lung cancer detected at its earliest stage (stage ia). Unfortunately, only a minority of lung cancer patients' fall into this category. For these patients who are healthy enough to tolerate surgical resection of the cancer or lung, median survival times are as high as 60 months (five years).
