I-Carcinomaofrectum
Incazelo emfushane:
I-Carcinomaofrectum ibizwa ngokuthi umdlavuza we-colorectal, iyisimila esibi esivamile emgudwini wokugaya ukudla, ukwenzeka kwayo kungokwesibili ngemuva komdlavuza wesisu nowe-esophagus, futhi iyingxenye evame kakhulu yomdlavuza we-colorectal (cishe u-60%). Iningi leziguli lineminyaka engaphezu kuka-40 ubudala, kanti cishe u-15% ungaphansi kweminyaka engu-30 ubudala. Abesilisa bavame kakhulu, isilinganiso sabesilisa nabesifazane singu-2-3:1 ngokusho kokubonwa kwezokwelapha, kutholakale ukuthi ingxenye yomdlavuza we-colorectal ivela kuma-polyps e-rectal noma i-schistosomiasis; ukuvuvukala okungapheli kwamathumbu, amanye angabangela umdlavuza; ukudla okunamafutha amaningi namaprotheni amaningi kubangela ukwanda kokukhiqizwa kwe-cholic acid, lokhu kokugcina kubola kube ama-hydrocarbons angagcwele yi-anaerobic yamathumbu, okungadala nomdlavuza.
Izizathu ezibangela umdlavuza we-colorectal
Ukuvuvukala kwamathumbu okungapheli
