A newer type of breast biopsy technique is the stereotactic biopsy which relies on a three-dimensional X-ray to guide the needle of non-palpable mass. The biopsy is performed in a similar manner, by using a needle to remove a tissue sample, but locating the specific area of the breast is done by X-raying the breast from two different angles.
A breast biopsy is usually done after a suspicious lesion is discovered on either mammography or ultrasound to get tissue for pathological diagnosis. [1] Several methods for a breast biopsy now exist. [ 2 ]
They are removed with a small margin of normal breast tissue if the preoperative clinical investigations are suggestive of the necessity of this procedure. A small amount of normal tissue must be removed in case the lesion turns out to be a phyllodes tumour on microscopic examination. [9] [21]
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]
In most cases breast cancers are asymptomatic and are detected by routine clinical screening exams. In about 30% of cases a breast mass may be felt. [13] [14] The mass will not fluctuate with the menstrual period. [15] Changes to the overlying skin including dimpling, pinching, orange peel-like texture, or nipple retraction may be seen. [16]
In addition, larger masses can stretch the overlying breast tissue leading to nipple retraction, chest wall fixation, and in advanced cases, ulceration from pressure necrosis. [ 6 ] Phyllodes tumors can grow to a variety of sizes, ranging from 0.8 to 40 cm, with the average tumor growing to between 4 and 8 cm. [ 7 ] Their growth can be slow ...
Micromastia (also called hypomastia, breast aplasia, breast hypoplasia, or mammary hypoplasia) is a medical term describing the postpubertal underdevelopment of a woman's breast tissue. [1] Just as it is impossible to define 'normal' breast size, there is no objective definition of micromastia.
Ductal carcinoma in situ (DCIS), also known as intraductal carcinoma, is a pre-cancerous or non-invasive cancerous lesion of the breast. [ 1 ] [ 2 ] DCIS is classified as Stage 0. [ 3 ] It rarely produces symptoms or a breast lump that can be felt, typically being detected through screening mammography .
