Mammography is a very effective test to diagnose breast cancer in the early stages, but the diagnosis could be simplified thanks to a new test - a simple blood test - developed in the UK by a team of researchers from Cancer Research UK ', the' Imperial College of London 'and the' University of Leicester '.

The new test is based on identifying in the blood of the patients markers in the DNA which are indicative of the presence of breast cancer, and according to scientists who have created it could also serve to detect other types of neoplasms such as lung cancer.

The first results with the new test to detect breast cancer suggest that it could be more accurate even than mammography

The first studies with this test have yielded positive results, suggesting that it could be more accurate even than mammography. To confirm this, the researchers will begin a trial involving 500 women included in a breast cancer screening program. They will obtain blood samples from the volunteers to compare them with those of patients who have been diagnosed and the pathology, in order to check whether the markers detected in the DNA of the latter can be associated with the presence of the disease.

If this new trial is successful, scientists will conduct further research to find out if the test could be used as a reliable method to detect breast cancer early in middle-aged or elderly women.

As explained by Dr. Jacqui Shaw of the University of Leicester, who is one of the authors of the finding, this test, if confirmed its effectiveness, could also be used to determine which are the most appropriate and effective drugs for each cancer tumor subtype of breast, and to check if the treatment is giving results.
