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]
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 ...
In particular, breast ultrasound may be useful for younger women who have denser fibrous breast tissue that may make mammograms more challenging to interpret. [ 3 ] [ 4 ] Automated whole-breast ultrasound (AWBU) is a technique that produces volumetric images of the breast and is largely independent of operator skill.
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 ...
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]
Breast ultrasounds may be used with or without a mammogram. Breast ultrasound is the use of medical ultrasonography to perform imaging of the breast. It can be used as either a diagnostic or a screening procedure. [38] It may be used either with or without a mammogram. [39]
A suspicious area on mammography or ultrasound. [9] This may include: Microcalcifications on MRI. [10] BI-RADS score of 4 or 5 on mammography, ultrasound, or MRI. [11] A suspicious hard palpable lump [9] Skin changes like crusting, scaling, or dimpling of the breast, which may signal an underlying breast cancer [9] Abnormal nipple discharge [7] [9]
An ultrasound beam is focused on a target in the breast and leads to tissue death and protein degradation by raising the temperature in that area. [27] Currently, the use of radiation is recommended in some cases, but HIFU in particular is not part of treatment guidelines. [ 28 ]
