New ways to detect hidden tumors at an early stage. Now with even more markers of Duisburg: October 9, 2008 – still cancer considered incurable, but the medicine has achieved so many successes in treating lately, that one assumes that you can cure many types of cancer, if you early enough could prove it. As well, it is that many people who have been cured of cancer, live in constant fear, that the cancer will come back, although has made all checkups. But thanks to the new methods of molecular medicine can be seen early on some types of cancer (at the time still not all!). Gene came such DNA tests developed for the detection of markers of breast cancer (breast cancer is the most common type of tumor in women). These tests were developed based on methods that are available and tested in the literature. To these methods is that you can make the investigation by blood and the tests are very accurate, because they are based on the PCR (polymerase chain reaction) method.
To this day, some need to Breast cancer patients undergo an investigation to the lymph nodes or bone marrow (biopsy) can be, which means a surgical procedure. Such biopsy samples are not repeatable. But blood samples you can freely remove and are associated with pain. Usually no breast tumor cells in the bloodstream can be found, it is because you have breast cancer. DNA tests are able to detect these tumor cells, because they are highly sensitive and highly specific.
Until now breast cancer prone women participate in mammograms and ultrasound tests as precautionary measures, these measures are not able to recognize the changes that take place at the molecular level. Such changes take place at a very early stage of the disease and are identified only through DNA testing. At the time, it offered the standard serological tests for the Brustkrebstumormarker.
