Trends Over Time
Between 1950 and 1991 deaths from lung cancer in the United States increased by 550%
In 1975 the one year survival rate for lung cancer was 34%. This survival rate increased to 41% in 1995 due to improvements in surgical techniques. 
Unfortunately, the five year survival rate for all stages combined has not changed in 30 years and remains at 14%.
