Developmental conditions that can effect breast shape include tube-like breasts, known as tuberous breasts, and a more profound developmental problem involves complete failure of breast development but the areola and nipple are present, known as Amazia. If the arealor and nipple also fail to develop this is known as Amastia.
In addition, your body weight, degree of chest muscle bulk, age and also hormonal influences during pregnancy and breast feeding can all influence breast shape.
Breast shape can be enhanced by surgical insertion of a correctly sized Motiva cohesive gel silicone breast implant and to internally release the tight bands that cause the tube like shape if needed. Fat taken from another part of the body following liposuction can also be used to enhance shape. In addition, the nipple and areolar position may have to be lifted (breast lift) or the size of the breast reduced in order to achieve the desired shape.
