More than 20,000 NHS patients are expected to take part at 200 or more GP practices.

To take part means to join an activity or study.

The patients will be 45 or older and will have visited a GP with abdominal symptoms, such as lasting bloating or discomfort.

These are health problems or changes felt in the belly area.

The tests will look for signs of several cancers in one blood sample.

A blood sample is a small amount of blood taken for testing.

A positive result is not a cancer diagnosis.

A positive result means the test found a sign it was designed to look for; it does not by itself prove cancer.

A positive result is not a cancer diagnosis.

A diagnosis is a doctor's decision about what illness a person has.

It can help the GP and patient decide whether an urgent referral for more checks is needed.

An urgent referral is a request for a person to see a specialist soon.

Why is that distinction important here?

A distinction is a difference between two things; here, it is the difference between guiding the next step and confirming cancer.
