Definition: Prognosis. Prognosis is a prediction of the chance of recovery or survival from a disease. Most physicians give a prognosis based on statistics of how a disease acts in studies on the general population. Prognosis can vary with lung cancer depending on several factors, such as the stage of disease at diagnosis, type of cancer, and even gender.
Doctors estimate prognosis by using statistics that researchers have collected over many years about people with the same type of cancer. 1  Several types of statistics may be used to estimate prognosis. The most commonly used statistics include: 2  Cancer-specific survival. This is the percentage of patients with a specific type and stage of cancer who have not died from their cancer during a certain period of time after diagnosis. The period of time may be 1 year, 2 years, 5 years, etc., with 5 years being the time period most often used.
