Breast aplasia: A rare condition wherein the normal growth of the breast or nipple never takes place. They are congenitally absent. There is no sign whatsoever of the breast tissue, areola or nipple. There is nothing there.
Breast aplasia (also called, amastia) is frequently not alone as the only problem. Unilateral amastia (amastia just on one side) is often associated with absence of the pectoral muscles (the muscles of the front of the chest). Bilateral amastia (with absence of both breasts) is associated in 40% of cases with multiple congenital anomalies (birth defects) involving other parts of the body as well.
Amastia is thought to be described in the Bible: “We have a little sister, and she hath no breasts” (Song of Solomon VIII:8).
Amastia can be distinguished from amazia — wherein breast tissue is absent, but the nipple is present — a condition that typically is a result of radiation or surgery.
- Breast augmentation
Artificial enlargement of the breasts. Breast augmentation may be done by insertion of a silicone bag (prosthesis) under the breast (submammary) or under the breast and chest muscle (subpectoral), after which the bag is filled with saline solution. This prosthesis expands the breast area to give the appearance of a fuller breast (increased cup size).
- Breast biopsy
A procedure in which a sample of a suspicious breast growth is removed and examined, usually for the presence of cancer. The sample is suctioned out through a needle or removed surgically. A breast biopsy may be done in a doctor’s office, outpatient facility, or hospital operating room. The setting depends on the size and […]

- Breast cancer
Breast cancer is diagnosed with self- and physician-examination of the breasts, mammography, ultrasound testing, and biopsy. There are many types of breast cancer that differ in their capability of spreading to other body tissues (metastasis). Treatment of breast cancer depends on the type and location of the breast cancer, as well as the age and […]
