What percentage of lung cancers is attributed to smoking?

The selection of 85% as the percentage of lung cancers attributed to smoking reflects a widely accepted statistic supported by numerous epidemiological studies and reports from organizations such as the American Cancer Society and the Centers for Disease Control and Prevention. Smoking is the primary risk factor for lung cancer, and the vast majority of cases are linked to tobacco use, particularly among long-term smokers.

This significant percentage underscores the strong causal relationship between smoking and the incidence of lung cancer, highlighting the importance of smoking cessation efforts and public health initiatives aimed at reducing tobacco use. The high correlation signifies that preventive measures targeting smoking can potentially lead to substantial decreases in lung cancer rates.

While other options present different figures, 85% is the most commonly cited and accurate estimate based on research within the field, reinforcing the message of the critical role smoking plays in the development of lung cancer.
