This study is looking at a new blood test to find many types of cancer early and to see if cancer has returned after treatment. The test uses cell-free DNA (cfDNA), which are tiny pieces of DNA from cells that float in your blood. Researchers want to see if this test can accurately detect cancers like brain, breast, bladder, cervical, and colorectal cancer. They are also studying if it can find very small amounts of cancer remaining after treatment, especially for lung cancer. You can join if you are 40 or older and have been recently diagnosed with one of the listed cancers, or if you don't have cancer. The study aims to detect cancer within 24 months. The current recruitment status is unclear.

Study design

This is an observational study involving 7000 participants, including people with and without cancer. It is designed to compare the blood test results between these two groups.

What's involved

You will provide a blood sample and clinical information at the start. Some participants with lung cancer will have additional blood draws every 3-6 months for up to 3 years after treatment. Other participants may have yearly follow-up for 3 years.

Compensation

Not stated in the trial record.

Follow-up

Participants with certain cancers will have follow-up for up to 3 years after treatment. Control participants will have follow-up for up to 3 years to check for cancer status.
