Le khansa ya m'mimba, wotchedwanso khansa ya m'mimba, imapangidwa kuchokera ku selo la parietal (selo la khoma la m'mimba), poyamba lodziwika bwino, lomwe limachulukirachulukira mwachisawawa, kupanga unyinji wotchedwa chotupa choopsa.

Oposa 90% ya zotupa zomwe zimayambitsa khansa ya m'mimba ndi adenocarcinoma, ndiko kuti, amakula kuchokera kumtunda wamkati wamimba, wotchedwa ntchofu. Ndi khansa yomwe imakula pang'onopang'ono ndipo sikadziwika kwambiri munthu asanakwanitse zaka 50.

The zotupa akhoza kukhala m`deralo kwa nthawi yaitali, pamaso kufalikira ku zigawo zina za chapamimba khoma ndi kuukira moyandikana ziwalo (pancreas, m`matumbo, ndulu) kapena lymphatic ndi mitsempha njira, kusiya maselo a khansa kuukira mwanabele, ndiye kufalitsa izi khansa. maselo a ziwalo zina monga chiwindi, ndi mapapo (metastasis).

Zina mitundu ya khansa ya m'mimba, monga chapamimba lymphoma (yomwe imakhudza mitsempha ya m'mimba), sarcoma (yomwe imakhudza minofu ya minofu) kapena chotupa cha m'mimba (chomwe chimayambira m'matumbo a ziwalo zomwe zimathandizira kugaya chakudya), ndizosowa kwambiri. Sizikambidwa mu pepala ili.

Zimayambitsa

Palibe chifukwa chenicheni cha khansa ya m'mimba, koma kutupa Kuchuluka kwa mucous membrane wam'mimba kumawonjezera chiopsezo, monga momwe zilili ndi gastritis Helicobacter pylori.. Khansara ya m'mimba imagwirizanitsidwanso ndi kudya, kwa nthawi yaitali, zakudya zamchere, zosuta kapena zokazinga, ndi zakudya zopanda zipatso ndi ndiwo zamasamba, komanso kusuta fodya.

Evolution

M'pamenenso khansa ya m'mimba imachuluka kuzindikiridwa msanga, kumapangitsanso mwayi wochira. Ikadakhalabe m'mimba, opitilira 50% mwa omwe akukhudzidwa adzakhala ndi moyo kwazaka zopitilira 5. Ngati wafalikira kudzera m'mitsempha ya mitsempha, zigawo za minofu, kapena ziwalo zina, kupulumuka kwa zaka zisanu ndi zosakwana 5%.

Ndani akukhudzidwa?

Zochitika zake ndizosiyana. Padziko lonse lapansi, khansa ya m'mimba imakhalabe 2^st chifukwa cha imfa ya khansa, koma ndi 4^st chifukwa ku Europe komwe wakhala akuchepa kwa zaka 20. Kuchepa kumeneku kumakhudzanso khansa ya "distal m'mimba", antrum ndi thupi. Kwa "khansa yoyandikira" ya cardia, izi ndi zotsutsana chifukwa maphunziro angapo amasonyeza kuwonjezeka kwa zochitika zake.

Khansara iyi imapezeka kawirikawiri pakati pa anthu omwe ali ndi vuto lazachuma, kapena omwe amadalira kwambiri chinsinsi ndi kusuta chifukwa kusunga chakudya. Japan, (1/1000 okhalamo,) China ndi Korea ndi ena mwa mayiko omwe akhudzidwa kwambiri.

Ku France chiwerengerochi ndi 12/100 mwa amuna ndi 000/4 mwa akazi. Mu 100 panali milandu 000 yatsopano pachaka. Ku Canada ndi United States, khansa ya m'mimba ndi zosawerengeka. Zili ngakhale kuchepa. Mu 2009, zidakhala zosakwana 2% mwa anthu onse omwe ali ndi khansa ku Canada.

M’mayiko otukuka, kuthira m’firiji kwathandiza kuchepetsa matenda a khansa ya m’mimba.
