Blood samples from 55 women who fought and won the battle with early stage breast cancer was analyzed by London researchers. As a result scientist say that they have developed a blood test that could determine if a relapse and the growth of tumors would occur in a former breast cancer survivor. The researchers searched for microscopic pieces of DNA found in the cancerous tumors that was removed.
Professor Mitch Dowsett says, “Normal imaging can only detect cancerous cells after they’ve grown.” This blood test will reveal cancer before a tumor forms. A larger study is planned for next year and the results from the study could take several years before the results become available to the patients. 54 out of the 55 former breast cancer patients, researchers predicted who would relapse.
