Barcelona, Spain: Patients with an early form of breast cancer are less likely to suffer a recurrence if they are post-menopausal or if their tumour is oestrogen receptor positive, according to research presented at the 11th European Breast Cancer Conference.
Although ductal carcinoma in situ (DCIS) is a non-invasive form of breast cancer, it can become invasive. Because little is known about which cases will progress, DCIS is treated in much the same way as other forms of breast cancer.
