breast cancer segment was found to be due to the deep penetration of
the breast mammography segment, which is among the oldest
segments of CAD application, this is because traditional methods as

traditional x-ray imaging lead the market in 2012 with USD 351.3
million. This is owed to the low cost and high penetration achieved by
the technology along with high knowledge of the technicality of the
imaging modality.
