Heavy and regular increased consumption of beer and liquors would cause an increased risk of lung cancer. Contrary to that a modest wine consumption is associated with a reduced risk for the lung cancer.

Chun Chao of the “Kaiser Permanenate Southern California in Pasadena “and his research team conducted this study. Results of meta-analysis after this study established the fact with sufficient experimental analyses and evidences. Findings of this study with detailed analysis have been published in the journal “Cancer Epidemiology Biomarkers and Prevention” recently.

All previously performed epidemiologic studies have indicated that beer, wine, and liquor may have different effects on the risk for lung cancer. Present study focused on the verification of all such previous claims.Chun Chao, from Kaiser Permanente Southern California in Pasadena, planned and conducted a comprehensive search of the ‘PubMed database’ to find studies that examined associations between alcohol consumption and lung cancer.

Subsequently the study planned for ten case-control studies included in the final analysis, resulting in a total of 4391 cases and 10,324 controls, along with four cohort studies. This comprehensive study therefore included a combined total of 453,751 participants. Approximately 4119 participants of these total participants developed lung cancer.

It was observed during this study that drinking beer once a day or more was directly related to an increased risk for lung cancer and the relative risk was 1.23 in comparison to those with no consumption.

People who are taking at least four servings of green salad every week and undertaking gardening once or twice a week have a reduced risk for developing lung cancer, regardless of whether or not they are smokers.

Dr. Michele Forman and his colleague research team presented the findings of this research study in the recently held ‘American Association for Cancer Research’s Frontiers in Cancer Prevention Research conference’ in Philadelphia, Pennsylvania, USA, Dr.Michele Forman and colleagues from the ‘MD Anderson Cancer Center in Houston, Texas’, examined data from an ongoing case-control study to develop separate epidemiologic risk assessment models for lung cancer in current, former, and never smokers.

Potential risk factors causing lung cancer included exposure to second-hand smoke and to dust; a cancer related family history, a history of respiratory disease in the index patient, and history of smoking. This model however revolves around certain limitations demonstrating modest discriminatory power.
