They estimate that this screening strategy would
reduce lung cancer mortality by 9.05 % compared to no screening, with an incremental cost - effectiveness ratio of $ 41,136 Canadian dollars per life - year gained.

Risk assessments estimate that lowering occupational exposure limits from the current to the proposed standard will
reduce silicosis and
lung cancer mortality to approximately one - half of the rates predicted under the current standard.
Now, on Nov. 5, a news story likened those findings to the results of a large trial by the National
Cancer Institute, which showed that CT scans reduced mortality rates among the highest - risk lung cancer patients by 20 pe

cancer patients by 20 percent.
The biological mechanisms by which toxins in tobacco smoke cause
lung cancer are complex and still not completely understood, but carcinogens in tobacco smoke may not only act as genetic inducers but also act to promote progression of the disease.6 7 As well as potentially
reducing the risk of
cancer related morbidity and
mortality, quitting smoking at diagnosis could
reduce overall
mortality, as smoking cessation
reduces mortality from other diseases such as heart disease, stroke, and chronic obstructive airways disease.8 9
It can pick up early
lung cancers and can
reduce mortality from
lung cancer by about 20 %, but a large number of the early lesions that are seen probably never would go on to being lethal
cancer and being able to discriminate between those that will cause trouble and those that won't make a huge difference in
cancer therapy.
Moreover, the paper gets its history wrong when it notes that «Total
cancer mortality rates did not decline until 1990, 25 years after the identification of the effect of smoking on
lung and other
cancers...» Well, actually, it was more like 50 years, because the earliest studies to connect smoking and
lung cancer were conducted not by NIH - funded scientists but by Nazi scientists in the run - up to World War II.4 By the logic of the PNAS paper, then, ought we to be crediting the Nazi health science agenda with whatever progress has been made on
reducing lung cancer, rather than the incredibly protracted and difficult public health campaign (that, for the most part, NIH had nothing to do with) aimed at getting people to cut down on smoking?
