Ixesha lesifuba libhekiselele kwiibele, ngokukodwa, iimbumba zobisi ebele. Igama lezilwanyana livela kwigama lesinyameko kwaye lisetyenziselwa ukubonakalisa izilwanyana ezondla iintsana zabo ngeengqayi zobisi zobunina (iinkomo zinezintlu ezinobumbele.)
Ngamanye amazwi, iintloko zezilwanyana zamancinzana zizifuba. Amanye amagama usebenzisa i-mammary ichaza izakhiwo ezifunyenwe ngaphakathi kweengcambu zamathambo okanye amabele.
Ngokomzekelo, i-term marmary ectasia iyakuthi ibhekise kwinkqubo eyenzeka kwi-breast trap, kulo mzekelo, i-milk and blocked milk conduit.
Inkcazo yee-Epithelial Cells
Iiseli ze-Epithelial zichazwe njengeeseli okanye izicubu ze-epithelium - uluhlu oluncinci lwezicubu ezibandakanya okanye ujikeleze ubuso beetyhubhu okanye izibilini ngaphakathi komzimba. Xa iiseli ze-epithelial zibe zibi (zibe ngumhlaza) zenza izicubu ezibizwa ngokuba yi-carcinomas. Phantse i-80% yamanomdla emzimbeni emzimbeni womzimba yi-carcinomas.
Kubeka ndawonye
Ukubeka iinkcazo kunye kunye, iiseli ze-epithelial cells ezilumkileyo ziseli zincinci zincinci zengubo ezigubungelayo kwaye zigqithise umgangatho wobisi obumbele. Kukho amanani amaninzi ngaphakathi kwe-lobule nganye eguqukayo kwi-lobes 15 ukuya kwe-20 yesifuba esendleleni eya kwi-tip. Kukho iintlobo ezikhethekileyo zala maseli e-epithelial cells. Amaseli e-epithelial kunye nama-methinalial amangqamuzana amancinci amabini ayenzeka kumathambo ebisi (bona umzekeliso).
Kubaluleka
Kulo mfanekiso, unokubona indlela amangqamuzana asemathambo angama-epithelial afaka ngayo i-milk ducts. Ingxaki ivela xa la maseli "engafi" kwaye akhule ngaphandle kokuyeka. Isinyathelo sokuqala senguqu yomhlaza kuthiwa i- ductal carcinoma in situ yebele (okanye i-DCIS,) imeko apho umhlaza uphelelwe khona ngaphakathi kwiduct kwaye ayifakwanga kwizicubu ezungezile.
Ngalesi nqanaba, iiseli azifaki ngaphaya komgca wecala kwaye zithathwa ngokuba "zangaphambi komhlaza."
I-DCIS ayisoloko iqhubela phambili kumhlaza, kodwa ngelanga, kwenzeka njalo.
Xa la maseli angaqhelekanga awela emzimbeni wesigxina - kwaye angena okanye angene ngaphakathi kwezinye izicubu - imeko leyo iyaziwa ngokuba ngumhlaza wesibeleko we-intraductal - ininzi yesifo somhlaza wesifuba.
Ukubiza: e-pu-THE-lee-al
Eyaziwayo Njengezi: iifetri ze-epithelial cells, zeseli ze-epithelial cells
Imizekelo: Amaseli e-epithelial amancinci afaka iidon and lobes zesifuba sakho, kwaye ezi seteli zivelisa ubisi lwebele. Uninzi lweziganeko zomhlaza wesisu zivela kwiiseli ze-epithelial.
