Kopans: New NEJM paper offers rehash on 'overdiagnosis'
In this Second Opinion article, Dr. Daniel Kopans of Massachusetts General Hospital comments on a paper on breast screening by Welch et al published this week in the New England Journal of Medicine. The Welch paper is based on false assumptions and makes the same mistakes as a 2012 paper on the same topic, according to Kopans.

Kopans: JAMA Oncology paper misinterprets DCIS data
Just how deadly is ductal carcinoma in situ (DCIS)? A paper by Narod et al published on August 20 in JAMA Oncology suggests that the best way to deal with DCIS is simply to ignore it, rather than treating it aggressively. But such conclusions represent a dangerous misinterpretation of the actual data, according to Dr. Daniel Kopans.

A response to Harding et al
The ploy used by Harding et al in their new study is classic. Explain why using your approach is scientifically unsupportable, and then go ahead and use it claiming there is no alternative.

Kopans: Breast cancer overdiagnosis grossly exaggerated
In this Second Opinion article, breast imaging expert Dr. Daniel Kopans offers his rebuttal of a study published last November in the New England Journal of Medicine, which raised questions about the value of screening mammography and claimed that a third of detected breast cancers represent "overdiagnosis."

Ultrasound nonmass breast lesion features may signal malignancy
By Amerigo Allegretto
Some nonmass breast lesion characteristics on ultrasound exams can be considered suspicious for malignancy at screening ultrasound.
November 5, 2024
Images depict a 43-year-old woman with a malignant non-mass lesion that was diagnosed as microinvasive ductal carcinoma. (A) Transverse and (B) longitudinal ultrasound images show a hypoechoic non-mass lesion (solid arrows) with segmental distribution in the left breast. The lesion has associated calcifications (dashed arrows in A). (C) Longitudinal color Doppler ultrasound image shows high vascularity. (D) Magnified image in the mediolateral oblique view from screening mammography shows grouped calcifications (arrows), which are considered a mammographic correlate of the ultrasound-detected non-mass lesion (A radiopaque marker attached to the skin is visible in the image because the mammographic exam was performed after screening breast ultrasound). Ultrasound-guided core needle biopsy and pathologic examination revealed ductal carcinoma in situ, but the lesion was upgraded to microinvasive ductal carcinoma at subsequent surgery (2.5-cm ductal carcinoma in situ, histologic grade II, estrogen receptor-positive, progesterone receptor-positive, human epidermal growth factor receptor type 2-negative).
