Leavitt believes her cancer was caused by Johnson & Johnson's Baby Powder and Shower to Shower - another powder containing talc sold by J&J in the past - which she used in the 1960s and 1970s.
Johnson & Johnson is facing some 13,000 similar lawsuits around the country.
The California Superior Court in Oakland agreed that the company's baby powder was a "substantial contributing factor" to her mesothelioma, a rare and aggressive cancer caused by the inhalation of asbestos. The jury decided against awarding punitive damages, which are created to punish the defendants - in this case Johnson & Johnson and the other companies involved in making the talcum powder - for reckless or negligent behavior.
Johnson & Johnson's baby-powder problems continued as a California jury decided the company must pay $29 million to a woman who claimed the company's talcum powder-based products gave her cancer.
J&J attorneys asserted in court that there's no conclusive evidence talc caused Leavitt's mesothelioma.
The company has appealed against all of the plaintiff verdicts, and the company said it was confident the verdicts would be overturned on appeal.
J&J said it would appeal, citing "serious procedural and evidentiary errors" in the course of the trial, saying lawyers for the woman had fundamentally failed to show its baby powder contains asbestos. "The jury verdicts are not medical, scientific or regulatory conclusions about a product", it said. Many of those cases allege that the talc is contaminated with asbestos and that Johnson & Johnson knew that its products were contaminated for decades, CNN reported. Cypress Mines, one of J&J's former talc suppliers, is answerable for the remaining 2 percent.
Fox News senior judicial analyst Judge Andrew Napolitano on the fallout from a report that Johnson & Johnson's Baby Powder contained asbestos and the company was aware of it for decades.
However, the Reuters report said that most testing found that there was no presence of asbestos in the company's products. They said their baby powder "is safe and asbestos-free".
"I don't think they made a good case" that J&J's Baby Powder "contained a significant enough amount of asbestos contamination to cause the illness", she said.
