We don't typically think of a mammogram as something to regret. Who could ever regret such a lifesaver?
Science is slowly convincing us, however, that more mammograms doesn't necessarily equal more lives saved. More mammograms, in fact, sometimes amount to marred lives.
Part of the reason some women are left wishing they never had a mammogram is that we currently treat nearly everything found by a mammo as if it were a threat to a woman's life. But a growing body of research shows we might do just fine leaving some suspicious spots alone.
