breast lesion

breast lesion

A generic term for a benign or malignant lump or bump in the breast.

Cancer risks by breast lesion
No proliferative disease; no increased cancer risk
• Apocrine change;
• Adenosis including florid;
• Duct ectasia;
• Mild epithelial hyperplasia of usual type.
 
Slight risk; 1.5–2-fold increase
• Hyperplasia of usual type, moderate or florid;
• Sclerosing adenosis, papilloma.

Moderate risk; 4–5-fold increase
• Atypical hyperplasia or borderline lesions;
• Atypical ductal hyperplasia or atypical lobular hyperplasia.
 
High risk; 8–10-fold increase
• Lobular carcinonoma in situ;
• Non-comedo DCIS.

Multicenter evaluation of the breast lesion excision system, a percutaneous, vacuum-assisted, intact-specimen breast biopsy device.
The volume presents up-to-date information on the areas of 3-D devices and techniques in the analysis of complex anatomical structures and the guiding/monitoring of interventional procedures; vascular applications including carotid artery analysis; breast lesion classification; 4-D US devices for assessing heart conditions; more precise 3-D maps for prostate cancer detection; and therapeutic applications including focused US and thermal ablations.
The area under the curve (AUC), time to peak (TTP), in-flow gradient (IFG) and peak enhancement (PE) were determined in a standardised manner for each focal breast lesion and the control/normal breast.
Chest computed tomography was also performed, which revealed a large pleural mesothelioma and an irregular breast lesion.
The pathology report following that surgery described the breast lesion as a malignant cystosarcoma phyllodes.
The second was to compare ultrasound alone versus the combination of ultrasound and ShearWave Elastography for breast lesion characterization.
However, before scheduling the patient for surgical excision in the operating room, every attempt should be made to determine, via percutaneous biopsy techniques (fineneedle aspiration cytology or core needle biopsy), whether the breast lesion is benign or malignant.
The addition of ShearWave Elastography features, such as maximum elasticity (stiffness) or heterogeneity (uniformity) of a lesion, to B-mode ultrasound, would permit an improvement in the BI-RADS([R])classification accuracy, (standardization tool for breast lesion classification from the American College of Radiology) improving breast diagnosis.
New FDA Clearance Allows for the Ability of the Intact Technology to Preserve Breast Lesion Architecture; Making a Reduction in Open Surgical Procedures a Potential
We then predict the benignity or malignancy of the breast lesion based on size of the lesion in the elasticity image compared to its size in the B-mode display.
In addition, a certain type of breast lesion, which in the past has been called "clinging carcinoma in situ," (1) is currently being encountered with increasing frequency in breast biopsies.
Because physicians treating women with breast cancer are particularly concerned about high-grade DCIS--the kind of breast lesion that is most likely to progress to invasive intraductal breast cancer--the researchers also performed an evaluation to determine which of the techniques had a higher sensitivity for diagnosing high-grade DCIS.
