A new blood test now under development can help detect 20 kinds of cancer, according to trials underway at the Dana-Farber Cancer Institute.

In trials, the test correctly identified 32% of patients with stage-one disease and 76% of those with stage-two disease, the institute announced.

Breast, colorectal and lung cancers were among those detected in blood samples.
The test showed an extremely low misdiagnosis rate — only 0.6% of healthy blood samples came back as incorrectly indicating cancer.
