– Kuhileleke ekugayeni ukudla ngokufihla ama-enzyme e-spancreatique. Lokhu okubizwa ngokuthi umsebenzi wayo i-exocrine.

- Idlala indima ebalulekile ekulawuleni izinga le-glucose egazini ngokuphuma kwayo kwamahomoni afana nala insulin futhi iglucagon. Lona umsebenzi wayo i-endocrine.

Ngaphezu kwe-95% yamathumba e-pancreatic athinta indawo lapho umsebenzi ukhona i-exocrine ama-pancreas, okusho ukuthi, lelo elenza ama-enzyme e-pancreatic adingeke ukuze kugaywe ukudla. Lezi ngokuvamile ziyi-adenocarcinoma. Leli shidi linikezelwe kuphela kulolu hlobo lwesimila.

Le dossier ayibhekani nezinye izinhlobo zomdlavuza we-pancreatic, ezingajwayelekile kakhulu, izimila ze-neuroendocrine (2 kuya ku-3% wezimila zama-pancreas), i-cystadenocarcinoma (i-1% yomdlavuza we-pancreatic), nezinye ezingavamile njenge-pancreatoblastomas, i-oncocytomas eyingozi, ama-acinar tumors. , kanye nezinhlobo ezahlukene ze-carcinomas.

Ukuziphendukela kwemvelo kanye nokusabalala

Umdlavuza we-pancreatic ubala cishe ama-2% amacala amasha omdlavuza atholwa unyaka ngamunye eCanada. E-France, inani lamacala amasha omdlavuza we-pancreatic lilinganiselwa unyaka ngamunye cishe ku-9000. Lithinta abesilisa nabesifazane, futhi iningi labantu abaneminyaka engu-50 noma ngaphezulu.
