After my article showing that prostate cancer screening with the PSA-test does more harm than good, I was asked to follow up with an article looking at breast cancer screening with mammography. That turned out to be easier said than done, because virtually all studies of breast cancer screening only report the effect of screening on breast cancer mortality, not on overall mortality.
Should you get a PSA test to screen for prostate cancer? What are the advantages and disadvantages of screening? Do the potential benefits outweigh the potential harms? Those are the questions we will seek to answer in this article.
