Cancer Screening Myths

worthwords says...

PSA In particular is not a good screening test.
And prostate unlike most other cancers in that for indolent cancers you can do more harm than good. So not broadly generalisable to all cancers.

Except it ignored that most early screening does lead to better results because early treatment always works better than later treatment (except in rare cases where no treatment is effective).

True, the statistics can be misleading, but you can use statistics to prove anything....forfty percent of all people know that.;-)

Cancer Screening Myths

agree, but here the explanation of lead time bias and overdiagnosis bias is reasonably good.
it's important to note that the studies were regrading primary care physicians who should know about screening and bias, but they are not cancer specialist (oncologist).
The male coming to see doctor asking for a PSA test because a celebrity said they should has presented a problem as doctors are afraid of litigation despite poor evidence for random PSA being a useful screening test. I believe the use of PSA as part of a 'medical' is far more common in the USA than Uk.

Ya, when all you need to add is the understood "in the mind of", I think it's more the listener's mind that's at issue.

A good party trick is to splash a few drops of acetone on polystyrene packaging - it instantly creates holes right the way trough like the Alien's blood.
Convince your guests that it's the strongest acid in nature and then stick your hand in it (even more effective if you are wearing nail varnish at the time).

seems logical. I was thinking with my stomach. I suppose edibility of oysters would depend on how clean the sea is at that point.

I'm guessing it's because over time the oysters will fill up those nooks and crannies between the rocks that are absorbing the energy. Eventually this may turn the complicated maze of directions the water can flow into something that performs more like the stepped gradient.
