Personalised DNA tests to easily detect breast cancer DNA in blood


Scientists introduce new DNA tests to detect breast cancer early using blood samples.
Use targeted digital sequencing (TARDIS) test to analyse fragments of tumour DNA in the blood.
Can detect extremely low concentrations of cancer cells in blood as an early detection method.
Need to study on more than 200 patients to further analyse what the test can show.
Analysed 80 blood samples from 33 women with early-stage and locally-advanced breast cancer.
Study by Translational Genomics Research Institute (TGen) in US, published in Science Translational Medicine.

With all these cancers on the rise, are we acting fast enough?
