When last I looked, J&J had $325 million in judgments against them in lawsuits over talc baby powder and its presumed role as a cause of ovarian cancer in several women. Even the International Agency for Research on Cancer, the people that believe hot beverages are probably carcinogenic, "… has since concluded there is only 'possible' evidence that perineal use of talc-based body powder may be carcinogenic." A new study in JAMA looks at four cohort studies with long-term information on talc use and subsequent self-reported ovarian cancer. It seems that possible may be too strong; they found no linkage.
