A landmark British study shows that almost half of all cancers diagnosed in 2010 stemmed from lifestyle and environmental factors.
For both men and women, smoking emerged as the top culprit, driving nearly 20% of new cancer cases.
Researchers drew these insights from data on 134,000 new cases of cancer across the United Kingdom, factoring in lifestyle and environmental exposures from roughly a decade prior.
Men: Following smoking tobacco, poor diet accounted for 6.1% of cases, trailed by occupational exposures, alcohol consumption, obesity, red meat intake, and UV radiation.
Women: Tobacco smoking led again, followed by obesity, infections, UV radiation, low fruit and vegetable intake, and alcohol consumption.
These authoritative findings appeared in the British Journal of Cancer.
