A University of Minnesota study reveals that heavy smokers who reduce their cigarette use compensate by taking more frequent puffs or inhaling deeper, leading to higher toxin exposure. The study suggests that quitting smoking is the most effective way to lower risk for tobacco-caused premature death.
A study found that close to half of smokers who underwent early-stage lung cancer surgery resumed smoking within 12 months, with 60% resuming in the first two months. Patients' self-efficacy and perceived pleasure from smoking drove their relapse rates.
A recent study published in Tobacco Control found that halving daily cigarette consumption has no significant health benefits. Among the participants who cut back on their smoking, women actually had higher death rates from all causes combined than heavy smokers.
A recent analysis of tobacco industry defense strategies reveals a shift in arguments as companies publicly admitted to smoking causing cancer. The study found that the industry initially claimed a lack of scientific proof and shifted its focus to mitigating factors and plaintiff free will as public admissions increased.
A Mayo Clinic review found that gene expression profiling has limitations in predicting lung cancer prognosis, with conventional methods remaining more accurate. Despite promising results, the technology's accuracy varies greatly among studies, and its clinical relevance is unclear.
Exercise has been found to reduce colon cancer risk in men who engage in moderate to vigorous exercise for a year.
