Le chirwere chepamu, iyo inonziwo kenza yemudumbu, inokura kubva pasero reparietal (sero riri mumadziro emudumbu), pakutanga rakajairwa, iro rinowanda nenzira yekusagadzikana, kuumba huwandu hunodanwa. chiremara chakaipa.

Pamusoro pe90% yemamota anokonzera gomarara remudumbu adenocarcinomas, ndiko kuti, vanokura kubva mukati mepamusoro pedenga redumbu, rinonzi mucous. Igomarara rinokura zvishoma nezvishoma uye risingawanzoonekwa munhu asati asvika makore makumi mashanu.

Mamota anogona kuramba ari munharaunda kwenguva yakareba, asati apararira kune mamwe maturu emadziro egastric uye anopinda nhengo dziri pedyo (pancreas, colon, spleen) kana ne lymphatic uye vascular nzira, zvichisiya masero ekenza kuti apinde mu lymph nodes, obva aparadzira kenza iyi. masero mune dzimwe nhengo dzakadai sechiropa, uye mapapu (metastasis).

mwe mhando dzekenza yemudumbu, zvakadai segastric lymphoma (iyo inokanganisa lymphatic system), sarcoma (inobata nyama yetsandanyama) kana gastrointestinal stromal bundu (iyo inotangira mumatishu enhengo dzinotsigira gadziriro yezvokudya), haiwanzoitiki. Hazvizokurukurwa mupepa rino.

Zvinokonzera

Iko hakuna chikonzero chaicho chegomarara remudumbu, asi kuzvimba chisingaperi mucous membrane yakanamatira mudumbu inowedzera njodzi, sezvinoitika kune gastritis Helicobacter pylori.

kushanduka

Kuwanda kwegomarara remudumbu kuongororwa kare, zviri nani mikana yekupora. Kana ichiri kuganhurirwa kumucheka wemudumbu, vanopfuura 50% yeavo vanobatwa vanozoirarama kweanopfuura makore mashanu. Kana yakapararira kuburikidza ne lymphatic system, muscle layers, kana dzimwe nhengo, makore mashanu ekupona ari pasi pe5%.

Ndiani anobatwa?

Chiitiko chayo hachina kuenzana. Munyika yose, gomarara remudumbu rinoramba riri 2^st chikonzero chekufa negomarara, asi iri 4^st chikonzero muEurope uko kwave kuderera kwemakore makumi maviri. Uku kuderera kwehuwandu hune chekuita negomarara re "distal dumbu", iyo antrum uye nemuviri. Kune "proximal cancer" yecardia, izvi zvinopokana nekuti zvidzidzo zvakawanda zvinoratidza kuwedzera kwechiitiko chayo.

Gomarara iri rinowanzoitika muvanhu vane mamiriro asina kunaka ezvehupfumi, kana kuti vanovimba zvakanyanya chakavanzika uye kusvuta nokuti kuchengetedza chikafu. Japan, (1/1000 mugari,) China neKorea dziri pakati penyika dzakakanganisika zvikuru.

MuFrance chiitiko chiri 12/100 muvarume uye 000/4 muvakadzi. Mu100 maive ne000 nyaya nyowani pagore. MuCanada neUnited States, kenza yemudumbu iri rova. Iri kutoderera. Muna 2009, yakaverengera isingasviki 2% yekese nyowani kenza pakati pevaCanada.

Munyika dzakabudirira, firiji yakabatsira kuderedza kuitika kwegomarara remudumbu.
