What is the difference between mammary duct and lactiferous duct?
Mammary Glands and Ducts The presence of sweat glands is a distinguishing characteristic for mammals. The glands and ducts of the female breast are similar to sweat glands.

How big is the lactiferous sinus collecting duct?
The normal collecting ducts are up to 2 mm in diameter; the lactiferous sinus is a mild dilation of the duct, usually measuring 3 to 4 mm. Posterior to the lactiferous sinus, the segmental and subsegmental ducts gradually decrease in caliber as they ramify.
How are fistulas of lactiferous ducts treated?
The most effective treatment of fistulas of lactiferous ducts is excision of the terminal portion of the involved mammary duct along with the indurated base of the sinus. Excision of the duct is best accomplished over a fine probe inserted into the duct and out of the nipple via ^the fistulous tract.
