Clues found aggressive breast cancer

Breast cancer is growing in women. The scientists are working hard to control it. They are working well to help this problem out. The collaboration teams of QIMR Berghofer Medical Research Institute along with the Institute of Molecular Bioscience (UQ) have worked hard to find a particular RNA (Ribonucleic acid) molecule that goes missing in the aggressive cancers. They have identified a different genetic ‘switch’ that can indicate whether a woman's breast cancer will spread further or not. Through this they can find out the real cause of spread. The lead researcher of the study QIMR Berghofer's Dr Nicole Cloonan explains, “Essentially, this particular gene fragment, or microRNA, normally acts like an emergency brake in our genetic program, ensuring our cells continue to reproduce normally. But we've identified that this "emergency brake" fails in invasive, aggressive tumours. Its sudden absence in cancer tests would be a clear marker that a tumour is likely to spread.”
