Scientists don’t publish “alarmist claims without data”. They publish scientific research which is reviewed by their peers and then built on or contradicted as needed. Scientists can’t just make stuff up - their papers are reviewed before they’re published and if they write crap, it doesn’t pass review. There have been several studies since the first paper on this so the link seems fairly robust.
Had you read the article and understood how science works, you’d have learnt that the the patients all had a form of cancer caused by asbestos, and their only exposure was via talc. You’d have also learnt that courts had already upheld the findings in previous litigation with expert testimony (this is where courts listen to scientists who provide evidence to support or refute the claims being made). So at this current stage there’s little doubt that the science is right, both in the scientific literature and in law (though of course there may be a missing piece of information that has not yet come to light).
Finally, I’d like to comment on your absurd remark “sometimes… was found to cause cancer”. Asbestos is an extremely dangerous carcinogen (thing that causes cancer), which is why we regulate it nowadays. The cancers are awful and often kill within 12 months of onset. It is frankly inhuman to suggest that any contamination of a product would be acceptable unless you’re the only one volunteering to die a horrible death.
If you’re not going to read the article or show any compassion for fellow humans then maybe don’t comment and let the mature adults discuss the issues instead.
