"We need to develop and further validate this test," said Ms. Alfattani. "However, these results are encouraging and indicate that it is possible to detect a signal for early breast cancer. After improving the accuracy of the test, it then opens the possibility of using a simple blood test to improve early detection of the disease. ”
Researchers are now testing samples from 800 patients and expect the accuracy of the test to improve with these higher numbers.
"A blood test for early detection of breast cancer would be cost effective," said Ms. Alfatani.
"This would also be an easier screening method to apply than current methods such as mammography."
R Researchers say that with sufficient investment, tests can be available in clinics in four to five years.
Similar methods are being tested for cancer of the lung, pancreas, bowel and liver.
"A blood test capable of detecting any of these early-stage cancers is an exaggerated purpose of our work," says Ms. Alfatani.
Dr. Kotryna Temcinaite, of Charitable Breast Cancer Now, says: "It is really promising that a simple blood test can in the future help doctors find autoantibodies that can occur before breast tumors develop. Although these are early findings, it is exciting that testing for these autoantibodies could potentially help detect breast cancer earlier or identify women who may benefit from closer monitoring. "
Dr. Iain Frame, NCRI Executive Director, stated: This pilot blood test for the detection of breast cancer is promising and is based on the expertise of this research group in other cancers, such as Obviously early days, but we look forward to seeing the results of a larger group of patients now being examined. "
Professor Paul Faroa, Professor of Cancer Epidemiology at Cambridge University, said that the early tests for cancer are a big research target, but said the study did not provide evidence that breast cancer can be seen five years before the onset of symptoms.
He expressed caution about the significance of the results, saying that the current sensitivity of the test was too low to be used as an early detection test.
