Description of intervention(s) / exposure
Questionnaire (survey) and a blood sample (optional).

Survey questions relate to lifestyle and risk factors a person may have been exposed to during their lifetime. Data from questionnaires of cancer patients and cancer free controls will be compared.

Blood samples will be analysed in the future in a quest to identify known or new biomarkers for disease. Data from blood analyses fror cancer patients and cancer free controls will be compared.

This is a one-off intervention: completion of one questionnaire and donation of one blood sample. There is no follow up for the participant.

Outcomes
Primary outcome [1] 269124 0
Survey questions relate to lifestyle and risk factors a person may have been exposed to during their lifetime.

Data from questionnaires of cancer patients and cancer free controls will be compared.
Timepoint [1] 269124 0
Data is to be supplied within 18 months of cancer diagnosis, but relates to the person's life.
Primary outcome [2] 269131 0
Blood samples will be analysed in the future in a quest to identify known or new biomarkers for disease.

Data from blood analyses fror cancer patients and cancer free controls will be compared.
Timepoint [2] 269131 0
Blood sample is to be supplied within 18 months of cancer diagnosis, and preferably before treatment commences.
Secondary outcome [1] 276981 0
Linkage to routinely collected data (eg NSW Central Cancer Registry, Registry of Births Deaths and Marriages, Admitted Patient Data, ABS, 45 and Up Study, Hereditary Cancer Registry ) will provde further information about the person's health and treatment

Summary
Brief summary
The NSW Cancer, Lifestyle, and the Evaluation of Risk (CLEAR) Study is a multi-centre case-control surveillance study in the NSW population. The objectives of the study are:
1. To provide ongoing data on the relative importance of known or emerging exposures and their relationships to leading or emerging cancer types.
2. To investigate in the short term once sample sizes permit, the effects of migration, ethnicity, physical activity, alcohol consumption, smoking, reproductive history, occupation, screening behaviour and certain dietary patterns on the risk of developing cancer of the colon and rectum, prostate, breast and lung, cutaneous melanoma and non-Hodgkin lymphoma.
3. To investigate in the longer term, once sample sizes permit, the effects of these factors on rarer cancer types, such as hepatoma, thyroid, ovarian and pancreatic cancers.
4. To develop a recruitment infrastructure and biological repository of sufficient size to enable the testing of new hypotheses on gene and environment factors, and in some situations, gene-environment interactions, on the risk of cancers affecting the Australian population.
