Potentially, as said, could represent cancers treated earlier saving
600 lives as well as 3900 (of 37000 high grade dyskaryosis) that
would on average have progressed to cancer.
Probably lives saved based on the cancers going untreated - but that
is purely guessing. Whatever the reason these figures seem unlikely
to represent any recognizable "truth".
The price is 215000 abnormal results of which 37000 were high grade
(bad) abnormalities and now that 1 mild dyskaryosis results in
colposcopy that must mean countless colposcopies.
However the death rate from CA Cervix has fallen significantly, see
for instance:
http://www.cancerresearchuk.org/cancer-info/cancerstats/types/cervix/mortality/uk-cervical-cancer-mortality-statistics#trends
The fall in death rate might suggest 940 lives saved at most in
England, and the only real question is whether a really determined
programme based on condom use as double protection might have saved
more lives, more STD and more terminations - but probably not.
Don't think doing nothing is or should be a realistic option.
