The study looks at how well the Galleri® blood test can find different kinds of cancer early, especially for people on Medicare, a health insurance for those aged 65 and older or with certain disabilities. The Galleri® multi-cancer early detection (MCED) test is designed to detect cancer from a blood sample before symptoms appear.

To join, you must be at least 50 years old, have Medicare, and be able to provide consent yourself. You cannot join if you had a similar cancer detection test before, are currently being checked for cancer, or are pregnant. The study is especially for those who haven't had certain cancers or cancer treatments recently. If you work for or with the company running the study, you also can't participate.

• Participants will undergo a blood test to check for multiple cancers.
• The study is available at multiple centers and seeks diverse participants.
• Current patients in participating centers can inquire about joining.
