Authors: Agarwal R, Diaz O, Lladó X, Gubern-Mérida A, Vilanova JC, Martí R Abstract Mammography is the gold standard screening technique in breast cancer, but it has some limitations for women with dense breasts. In such cases, sonography is usually recommended as an additional imaging technique. A traditional sonogram produces a two-dimensional (2D) visualization of the breast and is highly operator dependent. Automated breast ultrasound (ABUS) has also been proposed to produce a full 3D scan of the breast automatically with reduced operator dependency, facilitating double reading and comparis...

Hologic (NSDQ:HOLX) said recently that it won FDA 510(k) clearance for its Quantra 2.2 breast density assessment software and that it inked a development and distribution deal with Clarius Mobile Health for its wireless, handheld ultrasound scanner. The Marlborough, Mass.-based company said the Quantra 2.2 software uses a proprietary algorithm to analyze mammography images for the distribution and texture of breast tissue to produce patient-specific breast density assessments. “As the global leader in breast cancer screening technology, we relentlessly pursue the development of clinically superior products that ...

CONCLUSION: Outcome of loco-regional and bone relapses was good, suggesting that both systematic mammography and bone-scan/CT scan for high risk patients (N+, gradeIII) during the first 2-3 years may represent a tailored relevant follow-up protocol for breast cancer patients.

CONCLUSION: In contrast to optical methods, MSOT resolves physiological cancer features with high resolution and revealed patterns not offered by other radiological modalities. The new features relate to personalized and precision medicine potential. PMID: 28899968 [PubMed - as supplied by publisher]

Conclusion: These data indicate that TBBPA, triclosan, and BPA interact in vivo, consistent with evidence that TBBPA and triclosan inhibit enzymes that are critical for BPA and E2 metabolism. https://doi.org/10.1289/EHP1329 Received: 04 November 2016 Revised: 11 April 2017 Accepted: 13 April 2017 Published: 21 August 2017 Address correspondence to D. deCatanzaro, Dept. of Psychology, Neuroscience &Behaviour, McMaster University, 1280 Main St. West, Hamilton ON L8S 4K1, Canada.

The objective of the initiative is to improve the diagnosis accuracy in detecting breast cancer, specifically when reading ultrasound breast scans and mammograms. The project will take place in rural towns, areas where the cancer is common, and regions where medical practitioners are short staffed.According to Xinhuanet,breast cancer is the most malignant tumor found in Chinese females, and there were 272,000 new cases of breast cancer in China in 2015.Through feeding the machine hundreds of scans, the institute hopes it will eventually be able to interpret breast reports. The machine can read a report at lightening speeds...

Authors: Yoon CS, Kang SS Abstract Primary osteosarcomas of the breast are extremely uncommon. Here we describe a case of a 77-year-old woman who presented with a hard mass on her right breast. Mammography and breast ultrasound demonstrated a round-shaped calcified mass on the right breast but the features were not definitely diagnostic. For diagnostic purposes, an excisional biopsy was performed and the mass proved to be a primary osteosarcoma of the breast by pathologic findings. PET-CT and whole body bone scan showed neither evidence of metastasis nor underlying bone lesions. Wide excision without axillary lymph...

Positron Emission Tomography (PET) [1] has been widely used as an imaging modality in oncology [2]. Its applications include tumor detection, tumor staging [3], radiation planning [4], optimizing individual treatment planning [5], and probing tumor metabolism [6]. While whole-body (WB) PET has shown some utility in applications to breast cancer, the intrinsic spatial resolution of WB PET has limited its ability to detect smaller cancers (usually below 1cm) [7,8]. A variety of dedicated breast PET scanners often referred to as Positron Emission Mammography (PEM) systems have been developed to provide higher resolution, high...

Early-stage cancer detection could reduce breast cancer death rates significantly in the long-term. The most critical point for best prognosis is to identify early-stage cancer cells. Investigators have studied many breast diagnostic approaches, including mammography, magnetic resonance imaging, ultrasound, computerized tomography, positron emission tomography and biopsy. However, these techniques have some limitations such as being expensive, time consuming and not suitable for young women. Developing a high-sensitive and rapid early-stage breast cancer diagnostic method is urgent. In recent years, investigators have paid...
