Ngo-2017, ucwaningo olwanyatheliswa ku-Journal of the National Cancer Institute lwathi phakathi kwentsha eneminyaka engu-20-50 ubudala, izigameko zomdlavuza we-rectal ziyanda. Lesi sikhungo sasebenzisa idatha yokubhaliswa kwe-SEER evela ku-National Cancer Institute iminyaka engaphezu kwengama-35. Ngaphezu kwalokho, abacwaningi baphinde babikezele ukuthi ngo-2030, izehlakalo zomdlavuza wekoloni kanye nomdlavuza we-rectal zizokhula ngo-90% no-124% phakathi kwabantu abadala abaneminyaka engu-20-34! Isibalo sabantu abaneminyaka ephakathi kuka-35 no-49 sizokwenyuka sinciphe, ama-28% nama-46% ngokulandelana.
Emashumini amabili eminyaka adlule, nakuba ukwanda kokukhuluphala ngokweqile nokudliwa kwenyama kuye kwahlotshaniswa nengozi eyengeziwe yokuba nomdlavuza wekoloni, imibiko yomdlavuza wekholoni osanda kukhula kanye nomdlavuza we-rectal ikhombisa ukwehla ngokwesilinganiso ngonyaka cishe ngo-2.7%. Ukubhema kungesinye isici esandisa ingozi yokuba nama-polyps angaphambi komdlavuza kanye nomdlavuza wekoloni. Nakuba inani lababhemayo lehla lisuka ku-21% ngo-2005 laya ku-17% ngo-2014, ngokusho kweCenters for Disease Control and Prevention, kukholakala ukuthi iningi lokunciphisa ingozi yomdlavuza we-colorectal kungenxa yokuhlolwa okuthuthukisiwe nokuqapha ingozi yesiguli.
Kubantu ngabanye, ulwazi luyisihluthulelo. Kubalulekile ukunaka impilo yakho. Kubalulekile ukuqonda umlando womndeni wesifo somdlavuza wesikhumba kanye neminye imdlavuza ngangokunokwenzeka. Ngaphezu kwalokho, kufanele sinciphise izinto ezingakhuphula ubungozi besifo somdlavuza obala, njengokukhuluphala ngokweqile, ukusetshenziswa kwenyama ebomvu, ukudla okugayiwe nokubhema.
Izici ezinciphisa ingozi yomdlavuza obala:
■ I-fiber yokudla: Ubufakazi bangaphambilini bubonisa ukuthi i-fiber yokudla inganciphisa ingozi yomdlavuza we-colonary, futhi lo mbiko wengezwe ngokubika ukuthi amagremu angu-90 okusanhlamvu ngosuku anganciphisa ingozi yomdlavuza we-colorectal ngo-17%.
■ Izinhlamvu eziphelele: Ngokokuqala ngqa, ucwaningo lwe-AICR / WCRF ngokuzimela luxhumanise okusanhlamvu okuphelele kanye nomdlavuza obomvu. Ukutholwa okusanhlamvu okuphelele kunganciphisa ingozi yomdlavuza obala ngokwebala.
■ Ukuzivocavoca umzimba: Ukuzivocavoca umzimba kunganciphisa amathuba okuba nomdlavuza wamathumbu (kodwa abukho ubufakazi bokuthi wehlise amathuba okuba nomdlavuza wesikhumba).
■ Okunye: Ubufakazi obulinganiselwe bubonisa ukuthi inhlanzi, ukudla okunovithamini C (amawolintshi, ama-strawberry, isipinashi, njll.), amavithamini amaningi, i-calcium, nemikhiqizo yobisi nakho kunganciphisa ingozi yomdlavuza wesikhumba.
Izici ezandisa ingozi yomdlavuza obala:
∎ Ukudla kakhulu (> 500g ngesonto) inyama ebomvu kanye nenyama egayiwe, okuhlanganisa inyama yenkomo, ingulube, ama-hot dog, njll.: Ucwaningo lwangaphambilini lubonise ukuthi inyama ebomvu nenyama egayiwe kuhlotshaniswa nengozi yomdlavuza. Ngo-2015, i-International Agency for Research on Cancer (IARC), i-ejensi yomdlavuza ye-World Health Organization (WHO), yahlukanisa inyama egayiwe ngokuthi "isici somdlavuza kubantu." Ngaphezu kwalokho, ucwaningo lwabesifazane abangaphambi kokuya esikhathini luye lwabonisa ukuthi ukudla kakhulu inyama ebomvu kungandisa ingozi yomdlavuza webele. ≥ Phuza ≥ 2 izinhlobo zotshwala (30g utshwala) nsuku zonke, njengewayini noma ubhiya. ∎ Imifino/izithelo ezingezona isitashi, ukudla okune-heme iron: Uma ukudla kuphansi, ingozi yomdlavuza wekoloni iphezulu. ∎ Ezinye izici ezifana nokukhuluphala ngokweqile, ukukhuluphala, nobude nakho kungandisa ingozi yomdlavuza wekoloni. Izindlela eziningi zokuvimbela umdlavuza we-colorectal zibalulekile empilweni yonke: ukugcina isisindo esifanele, ukuzivocavoca umzimba ngendlela efanele, ukunciphisa inyama ebomvu nenyama egayiwe, ukwandisa ukudla okusanhlamvu kanye ne-fiber yokudla, ukunciphisa utshwala kuze kufike izingilazi ezimbili ngosuku, nokugwema. noma ukuyeka ukubhema. Kungenzeka yini ukugwema umdlavuza we-colorectal ngokufeza amaphuzu angenhla? Akekho ongaqinisekisa u-100%. Kodwa-ke, okungenani ohlelweni lokuvimbela umdlavuza, kuyacaca ukuthi "izimbangela" ezihlukene ziholela "ezithelo" ezahlukene, uyazi ukuthi ungakhetha kanjani.
