Effective measures for the primary prevention of adenocarcinoma of the lung include smoking cessation, eliminating secondhand smoke, reducing or eliminating exposure to radon, and reducing or eliminating occupational exposure to lung carcinogens.

Effective measures for the primary prevention of adenocarcinoma of the lung include:^[1]

• Smoking avoidance:

• Based on solid evidence, cigarette smoking causes lung cancer and therefore, smoking avoidance results in decreased mortality from primary lung cancers.

• Smoking cessation:

• Based on solid evidence, long-term sustained smoking cessation results in decreased incidence of lung cancer and of second primary lung tumors.

• Eliminating secondhand smoke:

• Based on solid evidence, exposure to secondhand smoke causes lung cancer and therefore, preventing exposure to secondhand smoke results in decreased incidence and mortality from primary lung cancers.

• Reducing or eliminating occupational exposure to lung carcinogens:

• Based on solid evidence, occupational exposures such as asbestos, arsenic, nickel, and chromium are causally associated with lung cancer. Reducing or eliminating workplace exposures to known lung carcinogens would be expected to result in a corresponding decrease in the risk of lung cancer.

• Reducing or eliminating exposure to radon:

• Based on solid evidence, indoor exposure to radon increases lung cancer incidence and mortality, particularly among cigarette smokers. In homes with high radon concentrations, taking steps to prevent radon from entering homes by sealing the basement would be expected to result in a corresponding decrease in the risk of lung cancer.
