“Many people think the only way to help research is to give a financial donation, but when it comes to a broad reaching study such as CLEAR, we’re totally reliant on the courage and goodwill of cancer patients in the community.”

Karen CanfelAssociate Professor Karen Canfell

“We have an enormous diversity of lifestyles: we can compare and get meaningful answers about the causes of cancer”
