A time-course Raman spectroscopic analysis of spontaneous in vitro microcalcifications in a breast cancer cell line.

Lab Invest 2021 Jun 11. Epub 2021 Jun 11.

School of Physics and Astronomy, University of Exeter, Exeter, UK.

Microcalcifications are early markers of breast cancer and can provide valuable prognostic information to support clinical decision-making. Current detection of calcifications in breast tissue is based on X-ray mammography, which involves the use of ionizing radiation with potentially detrimental effects, or MRI scans, which have limited spatial resolution. Additionally, these techniques are not capable of discriminating between microcalcifications from benign and malignant lesions. Read More

Granuloma after breast conserving surgery-a report of three cases.

J Surg Case Rep 2021 Jun 4;2021(6):rjab199. Epub 2021 Jun 4.

Department of Breast Oncology, Saitama Medical University International Medical Center, Saitama, Japan.

Granulomatous mastitis is a rare breast disease that is categorized as a benign tumor with chronic inflammation. Since the cause of the chronic inflammation is usually unknown, it is sometimes called idiopathic granulomatous mastitis (IGM). Although imaging modalities, such as ultrasound, magnetic resonance imaging and mammography can detect tumors, they are sometimes unable to differentiate between benign and malignant tumors.
