Deane Berg, who filed a first-of-its kind lawsuit blaming her ovarian cancer on Johnson & Johnson talc powders

Deane Berg’s doctor called her in the day after Christmas, 2006, to give her the crushing news. She’d had her ovaries removed, the pathology results were back, and they could not have been much worse.  Berg had stage III ovarian cancer, and her prognosis was poor.

Despite her 25 years as a physician’s assistant, Berg, then 49, knew next to nothing about ovarian cancer. Grappling with the “why me?” question, she studied the risk factors, finding just one that could apply: regular use of talcum powder for feminine hygiene.

Talc powder might be a cause ovarian cancer–who knew? It turned out that some people did.

With the introduction of DNA analysis three decades ago, criminal investigations and prosecutions gained a powerful tool to link suspects to crimes through biological evidence. This field has also exposed scores of wrongful convictions, and raised serious questions about the forensic science used in building cases.

This week, The Washington Post reported the first results from a sweeping study of the FBI forensic hair comparison unit, finding that 26 of 28 examiners in the unit gave flawed testimony in more than 200 cases during the 1980s and 1990s. Examiners overstated the accuracy of their analysis in ways that aided prosecutors.
