Prevention of Lung Carcinoma
No active interventions to prevent lung cancer are proven to be effective except for Smoking Cessation . Remediation of high radon levels in private residences removes known cancer-promoting radiation, but a reduction in lung cancer incidence is unproven. Increasing dietary intake of fruits and vegetables high in retinoids and beta-carotene appears to have no effect on lung cancer incidence. Vitamin supplementation is either unproven (vitamin E) or harmful (beta-carotene) in people who smoke. Evidence suggesting that nonsteroidal anti-inflammatory drugs (NSAIDs) andvitamin Esupplementation may protect people who formerly smoked from lung cancer has not been confirmed. Chemopreventive interventions, aside from smoking cessation, should be done only as part of a clinical trial. Molecular approaches targeting cell signaling and cell cycle pathways and tumor-associated antigens (precision chemoprevention) are under investigation.
