Blood test detects 12 different cancers

An experimental blood test may be able to detect a dozen different types of cancer with a high degree of accuracy, including some that are particularly difficult to detect, according to a preliminary study.

As the researchers report, the test was highly accurate at detecting cancer at an early stage — which is what any potential screening test should achieve. It also performed well in detecting certain cancers that show little evidence of their presence in the blood, making them harder to detect. The research team used blood samples from around 4,000 people – some without cancer and some with newly diagnosed cancers – to see how well the test could detect signs of a dozen types of tumours.

Overall, the researchers found, the test had an "area under the curve" (AUC) of 0.94 for detecting cancer. AUC is a measure of its accuracy

test ranging from 0 to 1: The closer to 1, the better.

When it came to early-stage cancer, the test's AUC ranged between 0.92 and 0.95, and in bladder, breast, kidney, prostate, and uterine cancers, it was also high (0.91).
