Is Tomosynthesis Better than Mammography at Detecting Breast Cancer?

New research shows digital breast tomosynthesis (DBT) to be a more effective breast cancer diagnosis tool than digital mammography (DM), according to a study recently published inRadiology. DBT is a relatively new screening practice and was only approved by the Food and Drug Administration in 2017. It uses an x-ray tube that glides in an arc-shape and uses low levels of radiation to image the breast from various angles. Up until now, research only showed us how effective the screening is in the first round of testing before detection rates are expected to escalate. Those early studies showed that DBT had higher detection rates than DM, and more patients were called back after showing suspicious areas in their scans. Lead study author and professor and chief of breast imaging at the Perelman School of Medicine at the University of Pennsylvania, Emily F. Conant, MD, ventured out to determine the accuracy and long-term outcomes of using DBT. They looked at over 56,000 DBT scans and 10,500 previous DM scans over a five-year period, and her team compared the findings to results from local cancer registries. Ultimately, the researchers found that DBT detected more cancer than DM, with 6 cases identified for every 1,000 DBT scans compared to 5.1 per 1,000 DM images. Recall rates for DBT was 8 percent whereas DM was 10.4 percent. Nearly a third of cancers detected by DBT had a weaker prognosis, and that figure was 25 percent for DM scans. These numbers remained constan...

We present a rare case of Paget disease of the nipple without the typical characteristics, detected by simple nipple scraping technique. A 62-year-old woman presented with a small fissure on the left nipple with scant clear nippledischarge. There were no other changes to the nipple-areola complex. The mammography and ultrasound were unremarkable. However, nipplescraping provided the immediate cytological diagnosis of Paget disease. Breast MRI with core biopsy showed high grade ductal carcinoma in situwith suggestion of microinvasion, confirmed histologically after mastectomy. Nipple scraping is a simple and inexpensive tec...

DISCUSSION: Breast primary must always be considered in the differential diagnosis in patients with sole presentation of axillary lymphadenopathy. The breast-specific immunomarkers play a pivotal role in the diagnosis of ER, PR-negative occult breast cancer. PMID: 32342946 [PubMed - in process]

Like everyone, I assume I’ll live forever. Although I often wonder whether anyone would come to my funeral and who would wear black, it never actually occurrs to me that there is an endpoint. It’s almost as if I would come along too to watch proceedings running smoothly and along the lines I wanted. Death was something I thought about, but in a rather abstract, offhand sort of way. It happened, of course I knew I would die at some point, but that point was somewhere out there … way off from here, where I am now. And then I hit a brick wall. The wall consisted of a tiny little bit of blood coughed up in s...

Jacinta E. Browne The aim of this work was to develop multimodal anthropomorphic breast phantoms suitable for evaluating the imaging performance of a recently-introduced Microwave Imaging (MWI) technique in comparison to the established diagnostic imaging modalities of Magnetic Resonance Imaging (MRI), Ultrasound (US), mammography and Computed Tomography (CT). MWI is an emerging technique with significant potential to supplement established imaging techniques to improve diagnostic confidence for breast cancer detection. To date, numerical simulations have been used to assess the different MWI scanning and image recon...

This article focuses on reviewing the background of microwave techniques for breast tumour detection. In particular, this study reviews the recent advancements in active microwave imaging, namely microwave tomography and radar-based techniques. The main objective of this paper is to provide researchers and physicians with an overview of the principles, techniques, and fundamental challenges associated with microwave imaging for breast cancer detection. Furthermore, this study aims to shed light on the fact that until today, there are very few commercially available and cost-effective microwave-based systems for breast canc...
