Baton Rouge, La Personal Injury Attorney Ed Kramer

Harvard MD testified that J&J Talcum Powder Caused Cancer

In a seminal trial being held in Missouri, a jury heard testimony from a Harvard epidemiologist that he has reached “medical and scientific certainty” that a woman’s daily use of Johnson & Johnson’s talcum powder products for four decades was the primary reason she developed ovarian tumors.  The plaintiff, Lois Slemp, had used J&J’s Shower to Shower products for decades and developed ovarian tumors.

It was in the tenth day of trial when epidemiologist and gynecologist Dr. Daniel Cramer was called to testify.  The defendants are Johnson & Johnson and Imerys Talc America, Inc., Johnson & Johnson’s supplier.

During testimony, Dr. Cramer testified that he had assessed the plaintiff’s medical and lifestyle factors.  Further opining, he stated that J&J’s talcum powder was the likely cause of her ovarian tumors, and that while Slemp’s obesity, family history of several different cancers and several decades of smoking all could have had some impact, it was her use of talc that weighed the most.

Dr Cramer stated that “First of all, she used talc daily for 40 years. That’s a lot of talc.”  “It was my opinion to a reasonable degree of medical and scientific certainty that Ms. Slemp’s genital use of talc was the major contributing cause and substantial cause in the development of her serious borderline tumor.”

Dr. Cramer also pointed out that Slemp had been genetically tested, and was found not to be carrying the genes BRCA1 and BRCA2, which are known to increase the risk of ovarian cancer.  Dr. Cramer further tested that it “almost speaks for itself” that the reason talc particles were found in the ovarian tissue Slemp had removed was the woman’s use of J&J’s talc-based baby powder and Shower to Shower products.

As an expert witness and researcher, Dr. Cramer is noted for being one of the first scientists to suggest a link between genital-area use of talcum powder and ovarian cancer.  This began with a 1982 study that Smith displayed for the jury. The attorney also had Cramer discuss an article he published in a medical journal in 1985 urging doctors to warn their patients away from using talc on their genitals.
