Following three weeks of trial, lawyers battling over the role Johnson’s Baby Powder may have played in a woman’s death from ovarian cancer spent four hours Thursday rehashing expert testimony and whether the company had any reason to think its talc-based product posed a health risk. 

“This is a big case with big issues that affect thousands of people, and about Johnson & Johnson protecting its corporate image,” said lead plaintiffs attorney R. Allen Smith, representing the granddaughter and estate of Diane Brower, who died in 2016. Brower purportedly used the powder on her vaginal area for more than 15 years before stopping around 1980.
