回答: Earlier detection seems a strong argument. 由 Latino2 于 2005-10-05, 17:21:51:

early detection does not change the probability of having breast cancer, but artificially shift the time of having breast cancer.

There was a surge of breast cancer when mammography first widely used.

Now after so many years of mammography, the breast cancer rate is even, and the staging of breast cancer is also more likely to be early stage for most women.
