Le kapamba ndi chimbudzi cham'mimba chomwe chimakhala chautali wa 15 cm, chokhazikika m'mimba, kuseri kwa m'mimba ndikutsekeredwa mu duodenum yomwe ili gawo loyamba la matumbo aang'ono.

- Imakhudzidwa ndi chimbudzi pobisa enzymespancréatiques. Izi ndi zomwe zimatchedwa ntchito exocrine.

- Imagwira ntchito yofunikira pakuwongolera kuchuluka kwa glucose m'magazi mwa kutulutsa kwake kwa mahomoni monga insulin ndi glucagon. Iyi ndi ntchito yake endocrine.

Le khansa pancreatic ndi chifukwa cha mapangidwe a chotupa choopsa, ndiko kunena kuti kuchuluka kwachilendo kwa maselo a khansa omwe angathe kufalikira kwina kulikonse m'thupi. Kupitilira 95% ya zotupa zam'mimba zimakhudza malo omwe ntchitoyo ili exocrine kapamba, ndiye kuti, womwe umapangitsa ma enzymes a pancreatic kukhala ofunikira kuti chimbudzi chigayike. Izi nthawi zambiri zimakhala adenocarcinomas. Tsambali laperekedwa kwa mtundu uwu wa chotupa.

Dongosolo ili siligwirizana ndi mitundu ina ya khansa ya kapamba, yomwe imakhala yochepa kwambiri, zotupa za neuroendocrine (2 mpaka 3% ya zotupa zam'mimba), cystadenocarcinoma (1% ya khansa ya pancreatic), ndi ena osowa monga pancreatoblastomas, oncocytomas oyipa, zotupa za acinar. , ndi mitundu yosiyanasiyana ya khansa.

Chisinthiko ndi kufalikira

Khansara ya kapamba imatenga pafupifupi 2% ya khansa zatsopano zomwe zimapezeka chaka chilichonse ku Canada. Ku France, chiwerengero cha matenda atsopano a khansa ya pancreatic chikuyembekezeka chaka chilichonse pafupifupi 9000. Zimakhudza amuna ndi akazi, komanso anthu ambiri omwe ali ndi zaka 50 kapena kuposerapo.
