Canadian researchers seek 10,000 toenail clippings to study trace elements linked to lung cancer risk.

Calgary-based researchers are collecting 10,000 toenail clippings across Canada to study potential links between trace elements and lung cancer risk. The project aims to analyze nail samples for mineral and metal content, which may offer insights into environmental factors contributing to lung cancer. Participants are encouraged to contribute clippings as part of a non-invasive, large-scale study.
