Breast self examination provides entry strategy

Given what is now known about the long subclinical growth phase
of human breast cancers, the finding of a recent study from Shanghai,
that teaching breast self examination did not detectably improve
survival, is not surprising.1 None the less, Austoker's related editorial, proclaiming the death of breast self examination, should not go unchallenged.2
Many studies have reported a reduction in primary tumour size dependent
on breast self examination, which may in turn enable more conservative
surgery.3 The editorial's implication that all such end
points are rendered illusory by the Shanghai study is overstated; as if
to acknowledge this, Austoker concedes that prompt symptomatic
presentation ("breast awareness") remains important. But is the
timely presentation of breast symptoms
of which palpation of a lump is
the commonest
so different from what most people understand by breast
self examination?
False positive and false negative "costs" are attached to breast
self examination
