Blood Test Predicts Relapse of Breast Cancer Before New Tumors Are Detectable
The technique uses personalized digital polymerase chain reaction (dPCR) tests to track mutations and could be applied to all subtypes of breast cancer.

‘Blood samples could be just as effective as tissue biopsies in analyzing the behavior of some cancers and the blood test accurately detects the higher levels of DNA present in cancer patients.’

The study showed how “circulating DNA” could be accurately detected and measured in the bloodstream. This type of blood test was similar to liquid biopsy which is more informative than normal biopsy. Dr Dawson’s research was based on the extensive analysis of blood and tissue samples from a 42-year-old breast cancer patient.Dr Dawson said, “Everybody had small fragments of DNA in their bloodstream. But cancer patients actually have much higher levels ... and that’s because the cancer itself can shed small amounts of this DNA into the bloodstream.”
“We’ve found that it very accurately represents the genetic changes that are present in the underlying cancer. We think we’ll be able to use this information to understand how well patients are responding to therapy and, if they’re not, try and predict what therapies might be better for that particular individual. From the patient’s perspective, it doesn’t mean anything more than a blood test, ” said Dr Dawson.
Blood Test May Predict Heart Attack Risk in Individuals With Chest Pain
The new blood test is a more sensitive troponin assay compared to standard versions as it can significantly detect lower levels of troponin in blood.
