Eating Soy May Confer Survival Benefit in Lung Cancer

According to results recently published in the Journal of Clinical Oncology, greater consumption of soy prior to a lung cancer diagnosis is associated with improved survival among women.

Clinical studies continue to unveil results that indicate diet and exercise play a significant role in the prevention and/or outcomes of certain cancers. Extensive research continues in this area to further elucidate details on associations between diet and cancer, so that individuals are able to receive accurate information from which to base their decisions.

Researchers from China collected data from the Shanghai Women’s Health Study, in which 444 women had been diagnosed with lung cancer. The women’s soy intake was assessed prior to their diagnosis of lung cancer.

Higher intake of soy foods prior to diagnosis of lung cancer was associated with higher overall survival.
The more soy that was included in a woman’s diet prior to diagnosis, the greater her chances of survival.
Although the mechanism for which soy intake may be associated with improved survival for lung cancer patients is not known, the researchers stated that “This study suggests, to the best of our knowledge for the first time, that, among women with lung cancer, prediagnosis intake of soy food is associated with better overall survival.”More studies are necessary to confirm this finding.
