German scientists from the University Hospital of Heidelberg developed a new method for the diagnosis of breast cancer - a liquid biopsy, which is a blood test for 15 biomarkers. The new method brings patients less stress and is not associated with radiation, say experts, writes medikforum.
breast cancer detection through the idea of the blood test is not new. German skilled technology could modify biopsy liquid (sample liquid substances organism) and to make it more effective. The effectiveness of the developed a new method of diagnosis of breast cancer up to 75%. For comparison gives mammography detection rate of about 78%.
"The new test will not replace the accepted diagnostic methods, but in the form of an additional type of screening, he could help detect breast cancer early," - said the development of the authors.
In particular, the researchers propose to use as a guide to developing breast cancer 15 specific biomarkers in the blood - tumor signal substances, which are available only in blood. Testing for these markers can (and should) make regular medical examinations procedure, scientists believe. This blood test, unlike today, the available methods of breast cancer detection (palpation, mammography, and MRI) can detect tumors at an early stage - this is its main advantage. Early detection of breast cancer increases the chance of survival to 95%.
"This test may be particularly useful for women aged up to 50 years at risk - those whose mother or grandmother suffered from breast cancer," - shared the opinion of experts.
