Ukusetshenziswa kotshwala kungaholela emiphumeleni eminingi enempilo emibi kakhulu, kodwa mhlawumbe okucwaningwa kakhulu futhi okuqoshiwe kuyingozi yokuphuza utshwala engozini yokuthuthukisa umdlavuza webele.
Kunezinqwaba zocwaningo zocwaningo oluye lwabonisa kaningi ukuthi abesifazane abaphuza utshwala banethuba elikhulu lokuthuthukisa umdlavuza webele kunabo abangaphuzi, futhi alukho uhlobo lokuphuza utshwala noma ngisho nokuvama kokuphuza okushintsha izingozi ezihilelekile.
Utshwala I-carcinogen
Kusukela ngo-May 2000, utshwala bubekwe ohlwini lwe-carcinogen eyaziwa ngumnyango wezempilo wezempilo waseMelika eMnyangweni wezeMpilo wezeMpilo wase-United States "Embikweni we-9 weCarogogens - Ukubuyekezwa Kwezinto EzokuLawulwa / UkuLawulwa" futhi kutholakale ukuthi unomthelela ekwenzeni ingozi yabaningi izinhlobo ezahlukene zegciwane.
Kodwa kulabo besifazane, umdlavuza webele uyisifo somdlavuza ovame kakhulu kunawo wonke abesifazane abayisishiyagalolunye abasengozini yokuthuthukisa lesi sifo ngesikhathi esithile sokuphila kwabo.
Iziphuzo Zansuku zonke Zengozini
Abesifazane abasengozini enkulu yomdlavuza webele yibo abanomlando womndeni wesifo. Futhi kulabo besifazane, ukuphuza utshwala kuyandisa kakhulu leyo ngozi.
Ucwaningo lweMayo Clinic lwabesifazane abangu-9 032 bathola ukuthi abesifazane abanobudlelwane obuseduze benomdlavuza wesifuba nabaphuza nsuku zonke babenezinkinga ezimbili zomdlavuza webele uma kuqhathaniswa nalabo abangazange baphuze. Kukhona olunye ucwaningo olubonisa ukuthi ukuphuza utshwala kwandisa ingozi yomdlavuza webele ngisho nalabo abangenalo umlando womndeni.
Abaphuzile abaNgeziNengozini
Nokho, abaphuzayo nsuku zonke akuzona iqembu elilodwa eliyingozi. Ucwaningo lweHarvard Medical School olwama-105 986 abesifazane lathola ukuthi ngisho nabaphuza ngokweqile babe nobungozi bokukhula komdlavuza webele.
Abesifazane abaphuza kuphela iziphuzo eziyisi-3 kuya kweziyisithupha ngesonto babe no-15% engozini, ngokusho kocwaningo, kanti abesifazane abaphuza isilinganiso seziphuzo ezimbili ngosuku bawandise ingozi ngo-51%.
Ucwaningo olufanayo lwathola ukuthi akukhathaleki uma abesifazane beqala ukuphuza besencane noma balinde kuze kube ngemva kweminyaka engu-40 - uma bephuza utshwala, ingozi yabo yanda.
I-Alcohol Engaphezulu, Ingozi Enkulu
Kunezifundo ezithile ezitholile ukuthi umphumela wokuphuza utshwala engozini yomdlavuza webele usuke uncike emtheni, okusho ukuthi utshwala obuthe xaxa, ingozi enkulu. Olunye ucwaningo lwathola ukuthi ukuphuza ngokweqile - iziphuzo ezingaphezu kwezingu-4 ngesikhathi sokuphuza okwesifazane - kwandisa ingozi yomdlavuza webele uma ngabe lezi zikhathi zazivamile noma cha.
Ucwaningo olwenziwe e-Radcliffe Infirmary e-Oxford, eNgilandi, abesifazane abayizinkulungwane ezingu-150 000 ababandakanyeka kwizifundo zangaphambilini ezingama-53 emhlabeni wonke baphetha ngokuthi ukuphuza ngokwephuzo olulodwa ngosuku kukhulisa ingozi yomdlavuza webele.
Ucwaningo lwamaBrithani lubuye lwathola ukuthi utshwala luyingozi engozini yomdlavuza webele, ngisho nalapho ukubhema kukhishwa. Eqinisweni, lolu cwaningo lwathola ukuthi ukubhema kwandisa ingozi yomdlavuza wamaphaphu, kodwa akukwandanga kakhulu amathuba okuba nomdlavuza webele.
Uhlobo Lotshwala Akuyona Into Eyona
Olunye ucwaningo luye lwabona ukuthi uhlobo lwotshwala oludliwe aluzange lube nomthelela engozini yokwanda. Ucwaningo luye lwabonisa ukuthi abaphuza ubhiya, abaphuza iwayini nabaphuzi be-whiskey bonke banamathuba afanayo okwandisa lesi sifo.
Ososayensi abaqiniseki kahle ukuthi ukuphuza utshwala kubangela kanjani ingozi yomdlavuza webele, kodwa abanye abacwaningi bacabanga ukuthi kungenxa yokuthi utshwala lushintsha amazinga we-hormone yesine estrogen.
Ucwaningo olulodwa lwathola ukuthi abesifazane abesilisa abesilisa abaphuza isilinganiso sezinyosi eyodwa nesigamu ngosuku babe nengozi enkulu engama-30% yomdlavuza webele, uma kuqhathaniswa nalabo abangaphuzanga nhlobo. Ucwaningo lubuye lwathola ukuthi abesifazane abano-hormone esikhundleni sokwelapha iminyaka emihlanu bephuza iziphuzo ezilodwa nesigamu ngosuku babenezingozi ezimbili.
Ingozi Ekhulayo Ye-Cancer Breast Recurrence
Kulabo besifazane abaye bathola ukuthi banesifo somdlavuza webele kanti nabani abasengozini yomdlavuza, ukuphuza utshwala kuyingozi.
Ukuphila Emva Kwesifo Se-Cancer Epidemiology Ucwaningo lwabesifazane abangu-1 897 lithole ukuthi ukuphuza iziphuzo ezimbalwa kuya kwezine ngesonto kungandisa ingozi yokuphindaphinda umdlavuza webele.
Umlando womndeni wesifo somdlavuza webele akusona kuphela okubangela indima engozini yomfazi yokuthuthukisa umdlavuza webele. Ezinye izingozi zibandakanya ukukhulelwa kwasekuqaleni, ukufika esikhathini sokuphela kwesikhathi, ukulibala ukubeletha kuze kube sekupheleni kwesikhathi, noma ukungabi nabantwana nhlobo.
Uma unesinye sezici eziyingozi, kanye / noma uma ungumlando we-postmenopausal, futhi / noma uma unomlando womndeni wesifo somdlavuza webele, ungakwazi ukunciphisa kakhulu ingozi ngokunciphisa ukuphuza utshwala noma ukungaphuzi nhlobo.
Uma uzama ukuyeka ukuphuza futhi uthole ukuthi unenkinga yokwenza kanjalo, kunesizwe sosizo nokusekelwa okukhona ukukusiza ukuyeka.
