  Code	Display
  ArchitecturalDistortion	Architectural distortion	Many breast masses are found within the zone of fibroglandular tissue or at a fat-fibroglandular junction. If the mass blurs a tissue plane between fat and fibroglandular tissue or if the mass produces distortion of the ducts, these findings may be termed architectural distortion. [Breast Imaging Reporting and Data System—Mammography, Fifth Edition page 139] Valid for the following modalities: MG US MRI.
  AxillaryAdenopathy	Axillary adenopathy	Enlarged axillary (under the armpit) lymph nodes. Additional evaluation is needed to determine the cause. [Breast Imaging Reporting and Data System—Ultrasound, Second Edition page 110] Valid for the following modalities: MG MRI.
  BiopsyClip	Biopsy clip	Tissue marker placement after image-guided breast biopsy has become a routine component of clinical practice. Marker placement distinguishes multiple biopsied lesions within the same breast, prevents re-biopsy of benign lesions, enables multi-modality correlation, guides pre-operative localization and helps confirm surgical target removal. Numerous breast tissue markers are currently available, with varied shapes, composition, and associated bio-absorbable components. [https://www.ncbi.nlm.nih.gov/pubmed/30059952] Valid for the following modalities: MG US MRI.
  BrachytherapyTube	Brachytherapy tube	Brachytherapy may be temporary or permanent. Temporary brachytherapy places radioactive material inside a catheter for a specific amount of time and then it is removed. It is given at a low-dose rate (LDR) or high-dose rate (HDR). Permanent brachytherapy is also called seed implantation. It puts radioactive seeds (about the size of a grain of rice) in or near the tumor permanently. After several months, the seeds lose their radioactivity. [https://www.radiologyinfo.org/en/info.cfm?pg=brachy] Valid for the following modalities: MG.
  ChestWallInvasion	Chest wall invasion	A tumor of the lung that has invaded the chest wall. Valid for the following modalities: MG US MRI.
  CooperDistorted	Cooper distorted	The cooper's ligaments are fibrous bands extending vertically from surface attached to chest wall muscles. These ligaments maintain the shape and structure of the breasts and help to prevent sagging. Cooper's ligaments support the breasts on the chest wall, maintain their contour, and keep them in position. Breasts become distorted if cancerous tumors grow on the ligaments. The normal breast contours can be noticeably different once distorted. This can be because of swelling, bulges, retraction, etc. Valid for the following modalities: US.
  CooperThickened	Cooper thickened	The cooper's ligaments are fibrous bands extending vertically from surface attached to chest wall muscles. These ligaments maintain the shape and structure of the breasts and help to prevent sagging. Cooper's ligaments support the breasts on the chest wall, maintain their contour, and keep them in position. These support breast tissue; and can become contracted in cancer of breast, producing dimples in overlying skin. Thickening occurs when there are skin changes usually associated with the presence of a mass, benign or malignant, that causes shortening in the Coopers ligaments due to fibrosis. Valid for the following modalities: US.
  Edema	Edema	Edema (swelling of the breasts) may be due to blockage of subdermal lymphatics by tumor cells or an inflammatory process within the breast or axilla. Valid for the following modalities: US.
  EdemaAdj	Edema adj	This is swelling of one or both breasts. A mammographic pattern of skin thickening, increased parenchymal density, and interstitial marking. Valid for the following modalities: US.
  GoldSeed	Gold Seed	Tiny, gold seeds, about the size of a grain of rice, that are put in and/or around a tumor to show exactly where it is in the body. The tumor can then be directly targeted and be given higher doses of radiation with less harm to nearby healthy tissue. Also called gold fiducial marker seeds, gold fiducial markers, and gold-seed fiducial markers. [https://www.cancer.gov/publications/dictionaries/cancer-terms/def/gold-seeds] Valid for the following modalities: MG.
  Hematoma	Hematoma	A hematoma is a localized bleeding outside of blood vessels, due to either disease or trauma including injury or surgery and may involve blood continuing to seep from broken capillaries. en.wikipedia.org > wiki > Hematoma Valid for the following modalities: MG.
  NippleRetraction	Nipple retraction	Retracted nipples lie flat against the areola. The condition can be the result of inflammation or scarring of the tissue behind the nipple, and caused by numerous conditions, not just cancer. In the case of breast cancer, nipple retraction occurs when the tumor attacks the duct behind the nipple, pulling it in. Valid for the following modalities: MG MRI.
  NOChestWallInvasion	NO Chest wall invasion	The mass has not attached itself to the chest wall. Valid for the following modalities: MRI.
  PectoralisMuscleInvasion	Pectoralis muscle invasion	Pectoralis muscle invasion is when a tumor has become large enough to invade into the pectoralis muscle. Valid for the following modalities: US MRI.
  PectoralisMuscleInvolvement	Pectoralis muscle involvement	Pectoralis muscle involvement of the tumor has been detected on the MRI by muscle enhancement with obliteration of the fat plane between the tumor and the muscle. pubs.rsna.org > doi > pdf Valid for the following modalities: MRI.
  PectoralisMuscleTenting	Pectoralis muscle tenting	The tent sign is a term referring to a characteristic appearance of the posterior edge of the breast parenchyma when a mass (usually an infiltrating lesion) causes its retraction and forms an inverted "V" that resembles the tip of a circus tent. [https://radiopaedia.org/articles/tent-sign-breast?lang=us] Valid for the following modalities: US MRI.
  PostSurgicalScar	Post surgical scar	Post surgical scarring happens because of the incisions needed to surgically remove tumor, cells, etc. The amount of scarring is connected to the different stages of wound healing. Surgical scar care should be continued for a year. Valid for the following modalities: MG.
  Seroma	Seroma	A breast seroma is a collection (pocket) of serous fluid that can develop after trauma to the breast or following procedures such as breast surgery or radiation therapy. Serous fluid is a pale yellow, transparent fluid that contains protein, but no blood cells or pus. [https://www.verywellhealth.com/seroma-medical-definition-430372] Valid for the following modalities: MG.
  SkinInvolvement	Skin involvement	The mass or lesion has attached itself to the skin of the breast. There are several layers of skin that the mass or lesion can penetrate and that is what determines the level of skin invasion. Valid for the following modalities: MG US MRI.
  SkinLesion	Skin lesion	A skin lesion is a part of the skin that has an abnormal growth or appearance compared to the skin around it.In order to diagnose a skin lesion, a full physical exam is necessary. Valid for the following modalities: MG.
  SkinRetraction	Skin retraction	Skin retraction (or inversion) or Skin retraction. Breast cancers that are located near the skin or nipple may cause scarring within the breast that pulls at the nipple or nearby skin. Skin and nipple retraction are more obvious when a woman raises her arms above her head or leans forward. [https://www.drholmesmd.com/blog/early-signs-of-breast-cancer] Valid for the following modalities: MG US MRI.
  SkinThickening	Skin thickening	The presence of skin thickening on mammography is variably defined, usually being more than 2 mm in thickness. It can result from a number of both benign and malignant causes. [https://radiopaedia.org/articles/skin-thickening-on-mammography-differential?lang=us] Valid for the following modalities: MG US MRI.
  SurgicalClip	Surgical clip	Most surgical clips are currently made of titanium, and as many as 30 to 40 clips may be used during a single surgical procedure. Surgical clips may remain inside the patient's body after the wounds are healed. Valid for the following modalities: MG.
  TrabecularThickening	Trabecular thickening	Trabecular thickening-thickening of the Cooper's ligaments and fibrous stroma-is an imaging finding of breast edema, usually secondary to dilated lymphatics. Skin thickening and trabecular thickening often occur together, and they have similar differential diagnoses. [https://oxfordmedicine.com/view/10.1093/med/9780190270261.001.0001/med-9780190270261-chapter-48] Valid for the following modalities: MG.
  CalcificationInMass	Calcification in mass	Calcifications usually can't be felt, but appear on a mammogram. Depending on how calcifications are clustered; shape, size, and number, further tests may be necessary. Larger "macrocalcifications" are usually not associated with cancer. Valid for the following modalities: US.
  CalcificationNotOnMammogarm	Calcification Not on mammogarm	Calcifications usually can't be felt, but appear on a mammogram. Calcifications can be clustered and their shape, size, and number.
