A breast cancer lawsuit based on trace levels of benzene in aerosol antiperspirant was dismissed with prejudice by a federal judge in Louisiana, because causation was not sufficiently pled. In particular, the plaintiffs failed to plead that (1) the plaintiff used a product that actually contained benzene and (2) benzene exposure can cause the plaintiff’s specific type of cancer. See Rooney v. Procter & Gamble Co., No. 22-11654, 2023 WL 1419870 (E.D. La. Jan. 31, 2023).
