A class action lawsuit filed against Johnson & Johnson seeks damages and medical monitoring on behalf of women diagnosed with cancer, or who might develop it in the future, allegedly as a result of using the company’s baby powder and other talc products.

The lawsuit was filed in New Jersey federal court. It is the first to seek medical monitoring, or regular testing meant to catch cancer early, on behalf of talc users. The move may include thousands of women, but would not include the more than 61,000 people who have already filed personal injury lawsuits over J&J’s talc, claiming it contains cancer-causing asbestos.

J&J maintains its talc is safe, asbestos-free and does not cause cancer.

The law firms behind the new case oppose J&J’s proposal to settle nearly all talc claims against it for $6.48 billion through a prepackaged bankruptcy. The same firms are pursuing a separate class action to block the bankruptcy.

The bankruptcy proposal needs support from 75% of talc claimants, with a three-month voting period ending on July 26.

More than a year ago, J&J spun-off its consumer business into Kenvue.
