Discovery that PARP Protein Exists in All Breast Tumors Will Help Target Chemo and Predict ResponseBreakthrough Method Predicts Risk of DCIS Becoming Invasive Breast Cancer
For the first time, scientists have discovered a way to predict whether women with ductal carcinoma in situ (DCIS) – the most common form of non-invasive breast cancer – are at risk of developing more invasive tumors in later years.
As a result of the finding, women with DCIS will have the opportunity to be more selective about their treatment, according to the scientists.
"Women will have much more information, so they can better know their risk of developing invasive cancer,'' said lead author Karla Kerlikowske, MD. "It will lead to a more personalized approach to treatment. As many as 44 percent of patients with DCIS may not require any further treatment, and can rely instead on surveillance.''
