The tit is made up from 12 - 20 lobe ; each lobe is made up from lobules , which are glandular structures ( glands ) that produce milk . The lobe and lobule are connected by lactiferous duct , which carry the Milk River . Multiple lactiferous ducts link up together and form an ampulla near the mamilla and open up up at the nipple . Below the nipple the lactiferous ducts form a reservoir for milk , which is call the lactiferous sinus . In - between the glandular tissue and canal , there are fat person tissues . There are no muscles in the breast . During puberty and gestation the breast size increase , the size increase during maternity is more uniformed .
How Do You Get Mastitis?
Lactating/Postpartum Mastitis
Mastitis is because of a blocked Milk River channel where the Milk River and secretion are not clear . This Milk River and secernment can back course to the nearby breast tissue paper and irritate the tissue causing inflammation . This inflammation is known as mastitis . If microorganism ( bacteria ) has access to this breast tissue then an infection can develop .
The liner of the lactiferous duct can undergo epidermalization ( transformation of glandular or mucosal tissue paper to ranked squamous tissue paper ) and keratin production . This can make plug of ducts . stop up duct can block the Milk River drain in lactating women . Then , the milk can back flow and stimulate fervor of the knocker tissue . Postpartum mastitis is realize usually during the second or 3rd hebdomad of postpartum ( period after pregnancy and delivery ) .
The organisms can enrol the breast through nipple cracks or crevice or sore nipples . ordinarily Staphylococcus aureus is the being that unremarkably have mastitis , but Staphylococcus epidermidis and Streptococci species also can cause mastitis . Nipple sores , fissures are due to miserable breast adherence and technique during breastfeeding . Infrequent feeding and missed provender can aggravate the infection . Mastitis can occur in one breast or it can occur in both breasts .
Non-Lactating Mastitis
Mastitis also occur in non - lactating women / peri - menopausal women due to the changes in the breast tissue and reduction of estrogen which conduct to duct ectasia . Duct ectasia is widening and shortening of a milk channel in the breast , the thickness of the duct paries increase and channel release a fluid which is thickheaded and sticky . This fluid and blocks the duct . Periductal mastitis ( PDM ) is also a type of duct ectasia , the milk ducts under the pap becomes widen and fill with a deep fluid and cause obstacle of the duct . The fluid buildup in duct ectasis and periductal mastitis can irritate the surrounding tissue paper , which lead to kindling of the breast tissue paper .
Smoking is learn in most of the women presenting with channel ectasia and periductal mastitis and it is said that the toxic meat in fag smoke directly or indirectly damages the paries of the Milk River channel , which direct to inflammation of the ducts . Additionally nipple offer , fissure or pierce can create a door for the organism to get inside the chest tissue paper and cause an infection on top of the redness .
Summary
Postpartum / wet mastitis is because of a blocked Milk River epithelial duct where the milk and secretions are not light up . This Milk River and secretion can back flow to the nearby breast tissue paper and irritate the tissue paper make inflammation . This inflammation is known as mastitis . If microorganism ( bacteria ) has access to this breast tissue through crack up nipples , crevice or mad nipples , then an contagion can develop . Usually Staphylococcus aureus , is the being that unremarkably cause mastitis , but Staphylococcus epidermidis and Streptococci coinage also can cause mastitis . Mastitis also occur in non - wet woman / peri - menopausal women due to the changes in the breast tissue and reduction of estrogen which leads to duct ectasia , and periductal mastitis ( PDM ) . PDM is also a type of duct ectasia . In canal ectasia and PDM , epithelial duct under the nipple becomes widen and fill up with a stocky fluid and cause obstruction of the duct which take to inflammation and infection if there are nipple cracks , sore or nipple pierce .
