Q. Are the cells in the breast really growing or are they just stretching? 

A. Cells are first stretched and then grow. The device creates a sustained mechanical tension, which is translated to the cell via biochemical signals. A gentle pull is placed on the breast tissue, the cells respond by developing new generated breast tissue growth.  Normal balance is restored and breast size is increased. MRI analysis of clinical participants indicated an overall proportional even increase in all elements (i.e., fat, fibroglandular tissue, etc.) of breast tissue.
