Researchers from the US and the UK have developed a blood test that can detect multiple types of cancer, according to a paper published in the Annals of Oncology.
The test works by analysing fragments of DNA released by cancer cells into the bloodstream. It is able to detect over 50 different cancer types, including lymphoma.
Scientists found that although the test could detect some very early cancers, it was more accurate at detecting cancers that were more advanced. In people with lymphoma, it was more accurate at detecting cancers that were stage 2 and above. Nevertheless, it could have the potential to detect cancers before people have noticed signs or symptoms. This could lead to earlier diagnosis and treatment.
The test is being studied in further clinical trials to confirm whether or not it is accurate and reliable enough to be used for routine screening.
