It is found that with the help of general cancer tests a tumour formed in the breast can only be detected approximately after 8 years when it started to grow. The tumour present in the breast by this time becomes to a mass sufficient enough that can be physically removed by surgery. Even mammography cannot detect the initial stages of cancer at ductal epithelium. There is a sequence that suggests that the cells at ductal epithelium convert into atypia, it is the root cause of carcinoma.
A technique in breast cancer diagnoses was introduced to find the breast ductal system complications by a visual aid. The technique named as mammary ductoscopy. It has become a promising technique that was developed and categories into the intraductal mechanism. The advantage is that early detection of tumour mass is possible than that of mammography technique. Its technology is restricted to ductal epithelium screening only, however, it helps to solve 85 % of the breast carcinoma caused in women.
