Mammograms that pick up what have been thought of as very early cancers, or DCIS, may in future just lead to lifestyle changes and monitoring.
Australian women with very early stage "breast cancers" are being given potentially unnecessary invasive treatment that may not decrease their risk of dying from the disease, a groundbreaking international study indicates.
The research has the potential to revolutionise mammogram screening programs across the world and breast cancer treatment – and even to change the very definition of what we call cancer, when it comes to the breast.
The study of more than 100,000 women, published in the prestigious JAMA Oncology journal, represents the most extensive data collection ever of the early-stage cancers, known as ductal carcinoma in situ, or DCIS.
