The TTHealthWatch podcast discusses lung cancer screening as a function of smoking duration and the association of antiviral herpes medications with Alzheimer's disease.[1] Recent studies show that the risk of lung cancer depends more on years of smoking than on the number of daily cigarettes; doubling the daily dose doubles the risk, and doubling the years of smoking increases the risk by five to six times.Smoking causes 90% of lung cancers in men and 80% in women.1[4] Screening can catch cancers in I. and Stage II cancers with cure rates of 80 to 95% and reduces mortality by 26% in men and 61% in women over a ten-year period.1 Other sources report that smoking causes 85% of lung cancers, 10% of passive smoking and 5% with no clear cause.[2] A pilot screening programme in Slovakia is targeting at-risk people aged 55-75 years who smoke at least one pack a day.6 A study in Slovakia confirms that the risk is 107-fold higher in male smokers and 10.1-fold higher in female smokers compared to non-smokers.7 [3] A study in Slovakia shows that the risk is 107-fold higher in male smokers and 10.1-fold higher in female smokers compared to non-smokers.
