SELECT Study Closes

The National Cancer Institute, the study investigators and the staff of the Coordinating Center wish to thank the study participants for their time and health information given to SELECT over the many years of the study since it started in 2001. Collection of routine SELECT follow-up data ends on May 31, 2014.

Participants who had consented to Centralized Follow-up were mailed a letter in May 2014 notifying them of the study closure. A copy of this letter can be found in Letters to Participants.

SELECT staff may be contacting you if you had already reported a cancer prior to June 1, 2014. Participants who had marked on their Centralized Follow-up Consent Form that they would like to know about any new substudies may also be contacted.

This website will continue to be available until May 31, 2015. Until that date, we will update this website if and when new information is available. More information about cancer, cancer prevention, and prostate cancer is available on the Resources page.
