A federal jury has awarded no damages to a woman who allegedly developed baby powder ovarian cancer side effects even after deciding that Johnson & Johnson failed to warn her of the carcinogenic properties of the product.

Deane Berg alleged that as a result of using the consumer giant’s Johnson’s Baby Powder for decades, she had been diagnosed with ovarian cancer. Doctors noted that when they looked at the tumor tissue, there were grains of talc. Harvard University research indicated that there could be thousands of women whose use of the powder and be exposed to ovarian cancer risks.

Scientists who examined eight case-control studies of 8,525 cases and nearly 10,000 controls noted that the use of talcum powder “is a modifiable exposure associated with small-to-moderate increases in risk of most subtypes of epithelial ovarian cancer” side effects. The study, published in a journal of the American Association for Cancer Research, has prompted state-level investigations closely followed by women and baby powder cancer attorneys.

Another study published in 2008 in the European Journal of Cancer Prevention found that there were studies dating back to the 1980s that indicated a link that would indicate the possibility of ovarian cancer for women who frequently used the products, including Shower to Shower and Johnson & Johnson’s Baby Powder, in the perineal area. However, the two public health experts that wrote the overview argued that significant research oversights existed.

They recommend that future studies should examine and separate different methods of applications and other usage and try and compare those to historical usage patterns of talcum powder products.
