Re: America's Affordable Health Choices Act of 2009 - Part 2 - Deathers vs. Commies
If the test costs, say 1/100th of the later treatment (say, $1,000 vs. $100,000), then you have to catch a case for every 100 tests to make the test "worth it" (from a purely cost point of view). Even if the incidence rate of cancer in the population you're talking about were as high as 1 in 1,000, then 100 tests will, on average, catch only 0.1 cancers (assuming zero false negatives) - so we (as a society) would end up spending 10x as much on testing as we would have on the later treatment. I'm sure these numbers are wrong, but perhaps not unreasonable.
You have to look at the actual numbers involved - not just say "X will get worse or Y will get better." That doesn't mean anything. How much worse? How much better? At what cost?
*And lest you think I'm just being callous, my mother had her first case of breast cancer at age 49, followed by a completely different kind unrelated to the first at age 53. She's since completed 14 marathons and is still going strong at age 65. She found the first lump herself - not via a prescreening mammography.
You're painting with a pretty simplified brush here. What's the cost of the test? What's the rate of false positives and negatives? What's the actual incidence rate of breast cancer? What is the actual ratio of cost between a lumpectomy and the more involved kind?If we have all these women with very nasy, involved cancers instead of the little lumpectomy kind the cost of treatment would be significantly higher...

And that's where the value judgement comes in. Is it worth spending the extra money for testing to reduce the death rate of women between 40 and 50? Well, that all depends on how much value we put on a human life.leswp1 said:...and the risk of death for those women who would be caught later would be extremely high.
Was that the only factor that changed? Obviously not. Treatments changed, awareness changed, etc, etc. And by how much did the death rate change? And even if it was say, cut in half, did it drop from 1 in 1000 to 1 in 2000 (pretty significant), or from 1 in 500,000 to 1 in a million (pretty insignificant)?les1p said:The deathrate from breast CA dropped correlated to the institution of early mammo (I remember seeing this in nursing school when they showed the graph of deaths from breast CA before and after screening was instituted).
