A breast mass, also known as a breast lump, is a localized swelling that feels different from the surrounding tissue. [1] Breast pain, nipple discharge, or skin changes may be present. [1] Concerning findings include masses that are hard, do not move easily, are of an irregular shape, or are firmly attached to surrounding tissue. [2]
The periareolar glands of Montgomery in the breast are also called Montgomery tubercles or Morgagni tubercles. These periareolar glands are small, papular tissue projections at the edge of the areola (nipple).Obstruction of the Montgomery tubercles may result in an acute inflammation, a clear or light brownish fluid may drain out of the areola (nipple discharge), and an subareolar mass may ...
The "Egan technique", as it became known, enabled physicians to detect calcification in breast tissue; [68] of the 245 breast cancers that were confirmed by biopsy among 1,000 patients, Egan and his colleagues at M.D. Anderson were able to identify 238 cases by using his method, 19 of which were in patients whose physical examinations had ...
Mammotome is a Cincinnati, Ohio–based company who pioneered a vacuum-assisted breast biopsy (VAC) device that uses image guidance such as x-ray, ultrasound and/or MRI to perform breast biopsies. A biopsy using a Mammotome® device can be done on an outpatient basis with a local anesthetic .
An ultrasound can detect abnormalities in the breast tissue by using high-frequency sound waves that bounce off the tissue that then transform into images that can be interpreted. It has been shown to be more useful in searching for masses in dense breast tissue. [16] Ultrasounds have a sensitivity of 76% and specificity of 84%. [17]
Desmoid tumors of the breast are rare, constituting 4% of extra-abdominal cases and 0.2–0.3% of breast tumors. [27] [24] Although benign, they can mimic breast cancer on physical examination, mammography and breast ultrasound and can also be locally invasive. Even though they occur sporadically, they can also be seen as a part of Gardner's ...
Lumpectomy (sometimes known as a tylectomy, partial mastectomy, breast segmental resection or breast wide local excision) is a surgical removal of a discrete portion or "lump" of breast tissue, usually in the treatment of a malignant tumor or breast cancer. [1]
Affected ducts have characteristic necrotic tissue which is composed of multiple, well-defined firm masses of dead cells. In most cases of comedocarcinomas (approximately 78%), [6] mammograms will reveal micro-calcifications in the breast tissue due to the calcification of necrotic elements. Upon physical examination, the infected area can ...
