Blood test may aid in lung cancer diagnosis and reduce unnecessary invasive procedures
— 15:05 GMT | HealthOf the nearly 150,000 abnormal chest X-rays performed each year in the United States, 25 percent of patients will display only benign lung pathologies on further surgical examination…
Green tea could modify the effect of cigarette smoking on lung cancer risk
— 15:00 GMT | HealthDrinking green tea could modulate the effect of smoking on lung cancer. Results of this hospital-based, randomised study conducted in Taiwan were presented at the AACR-IASLC Joint Conference on Molecular Origins of Lung Cancer, held here from Jan. 11-14, 2010…
In early heart development, genes work in tandem
— 14:55 GMT | HealthStudying genes that regulate early heart development in animals, scientists have solved a puzzle about one gene's role, finding that it acts in concert with a related gene. Their finding contributes to understanding how the earliest stages of heart development may go awry, resulting in congenital heart defects in humans…
