The CLEAR Study – what really causes cancer?

What really causes cancer?

Lifestyle? Genes?   Help us find the answers.

We invite scientists to make use of this unique resource!

What is the CLEAR Study?

The CLEAR Study is a data and biobanking initiative which  provides researchers with  the most comprehensive information ever gathered about the lifestyle and genetic factors that influence cancer in the NSW community.

The findings of this ground-breaking study are expected to lead to a much better understanding of what causes cancer.

Scientists interested in using the CLEAR Study data may now submit applications. At December 2014 there are over 10,800 participants in the study. Data and blood samples are available for  7,662 participants (n= 5,896 cases and n= 1,766 controls). See

What does it involve?

The CLEAR Study is NOT currently recruiting, As recruitment and blood collection ceased in June 2014.

Participants in the CLEAR Study completed a survey, and provided a small blood sample (optional).  Both are a one-time-only activity, and there are no further obligations. It’s that simple to help us find the answer to “what really causes cancer?”

Why help?

If you or a loved one has been diagnosed with cancer, you’ll know that one of the first questions asked is “why?”. CLEAR is the first study of its kind in NSW, so the participants who took part in the CLEAR Study will be helping Cancer Council NSW find the answers to that often-asked question “what really causes cancer?”.

Cancer Patients speak about the CLEAR Stud.



If you have further questions about how the CLEAR Study was conducted, please see more information for participants on our FAQ page.
