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 density is assessed by mammography and expressed as a percentage of the mammogram occupied by radiologically dense tissue (percent mammographic density or PMD). [23] About half of middle-aged women have dense breasts, and breasts generally become less dense as they age. Higher breast density is an independent risk factor for breast cancer.
A review of 10,485 individuals all of whom had early stage N1 (<2 cm. in size) or N2 (2 to <5 cm. in size) IPC tumors that had not metastasized to lymph nodes or distant tissues reported that lumpectomy plus adjuvant radiation therapy produced significantly better mean survival times (16.8 years) than lumpectomy (14.2 years) or mastectomy (14.9 ...
The rate of death due to breast carcinoma was also influenced by grade, with 90% occurring in 40, 13, and 8 years among patients with grades 1, 2, and 3 tumors, respectively.” [12] [30] Immunohistochemistry of breast cancer (Infiltrating ductal carcinoma of the breast) assayed with anti HER-2 (ErbB2) antibody.
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 ...
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
Fibrocystic breast changes is a condition of the breasts where there may be pain, breast cysts, and breast masses. [1] The breasts may be described as "lumpy" or "doughy". [ 3 ] Symptoms may worsen during certain parts of the menstrual cycle due to hormonal stimulation. [ 1 ]
To prevent the need to pierce the breast repeatedly, a coaxial needle is left in place on top of the mass as a guide. [11] CNB has a higher sensitivity for cancer than FNA, has lower false negatives, and has proven more successful in finding rare breast diseases like lobular carcinoma. However, this method still has relatively high rates of ...
