Under Withdrawal option #1 and Withdrawal option #2:

  • We will not invite you to participate in any future study components or sub-studies and we will not send you any further updates about the progress of the study.
  • We may continue to use the information and samples you have already provided.
  • We will not obtain any new information about you from hospitals, pathology laboratories, or the Victorian or Australian Electoral Commission.

Withdrawal option #1

We may continue to obtain new information about you from cancer and death registries. This will allow you to continue to contribute to cancer research without receiving any further contact from us. Any information obtained will remain confidential.

Withdrawal option #2

We will not obtain any new information about you from cancer and death registries.

After you withdraw, we may discover genetic information through our research that may be relevant to you and your family. Only a small number of people who participate in research will have important genetic information identified that may be relevant to them and/or their family. Please indicate whether you would like to receive this information. Further information to help you make this decision can be found here.

Processing... Please wait.
