Amar Rewari, Chief of Radiation Oncology at Luminis Health, shared a post on LinkedIn:
“Not everything that ’causes cancer’ on social media actually causes cancer.
I recently spoke with PEOPLE Magazine | PEOPLE.com about concerns surrounding dryer sheets and fabric softeners.
One of the points I emphasized was:
‘I think it is important to separate possibility from proof.’
Some studies have found that fragranced laundry products can release chemicals that warrant further research.
But identifying a potentially concerning chemical is not the same thing as proving that a product causes cancer in people.
As I told People:
‘From a cancer standpoint, we do not have strong evidence showing that typical household use of dryer sheets or fabric softeners directly causes cancer in humans.’
‘The biggest mistake I see is people becoming overly worried about a single household product while overlooking risk factors that we know have a much larger impact on cancer risk.’
The goal isn’t to ignore potential risks. It’s to focus our attention where the science is strongest.
Thank you to Angelique B. and PEOPLE Magazine | PEOPLE.com for the opportunity to discuss the evidence behind the headlines.
