The American Cancer Society is recruiting Tucson participants to sign up online for a new landmark, cancer research study.

The nationwide Cancer Prevention Study-3 is seeking 300,000 U.S. men and women between the ages of 30 and 65 who are willing to commit to the long-term study, completing follow-up surveys at home for the next 20 to 30 years.

Officials with the American Cancer Society in Tucson are aiming to have at least 500 local people sign up.

Volunteers must never have been diagnosed with cancer (not including basal or squamous cell skin cancer). The enrollment period is Oct. 16-25.

Enrollment in CPS-3 is a two-step process. The first step after signing up online is to schedule an appointment and complete a 30-to 40-minute survey at home.

At the appointment, prospective participants will complete a shorter survey, that may take about 15-20 minutes, and then provide a blood sample and waist measurement at a local site. Then every two years or so, participants will be sent a follow-up survey to complete at home over the next two to three decades.

Two out of three people diagnosed with cancer live at least five years after diagnosis. The American Cancer Society is aiming to raise that number to three out of three in the coming years.
