Welcome back MGF. The study you describe is very interesting. There is now some thought that "heavy" smokers who have smoked a long time get the CT scans. while there is evidence of some benefits in the 20% reduction in lung cancer deaths, the cost associated with the studies don't appear to warrant wide spread screening. However, that is based upon statistical analysis and costs to society. But to the individual, what is the cost? Yes most long time heavy smokers may expect consequences, and even accept them, but would likely spare no expense for an individual "cure." Would society deny that "cure" because they "did it to themselves?" With dwindling resources (money) and a growing desire to reduce government expenditures, such testing may not happen anyway.
Just my 2 cents
