Le umdlavuza wesisu, ebizwa nangokuthi umdlavuza wesisu, ikhula isuka kungqamuzana le-parietal (iseli esodongeni lwesisu), ekuqaleni evamile, eliphindaphindeka ngendlela ye-anarchic, ukuze yakhe isisindo esibizwa ngokuthi isimila esiyingozi.

Bangaphezu kuka-90% amathumba adala umdlavuza wesisu i-adenocarcinoma, okungukuthi, zikhula kusukela ongqimbeni olungaphakathi olungaphakathi lwesisu, olubizwa ngokuthi amafinyila. Kungumdlavuza oqhubeka kancane futhi ongavamile ukubonakala ngaphambi kweminyaka engama-50.

Izimila zingahlala zisendaweni isikhathi eside, ngaphambi kokuba zisakazekele kwezinye izingqimba zodonga lwesisu futhi zihlasele izitho eziseduze (amanyikwe, ikholoni, ubende) noma ngomzila we-lymphatic nemithambo, okushiya amangqamuzana omdlavuza ukuthi ahlasele ama-lymph nodes, bese asabalalisa lo mdlavuza. amaseli kwezinye izitho ezifana nesibindi, namaphaphu (metastasis).

Izincwajana zemininingwane izinhlobo zomdlavuza wesisu, njenge-gastric lymphoma (ethinta isimiso se-lymphatic), i-sarcoma (ethinta izicubu zemisipha) noma isimila se-stromal yamathumbu (eqala ezicutshini zezitho ezisekela uhlelo lokugaya), ziyivelakancane kakhulu. Ngeke kuxoxwe ngakho kuleli shidi.

Izimbangela

Asikho isizathu esiqondile somdlavuza wesisu, kodwa ukuvuvukala Ulwelwesi lwamafinyila olungamahlalakhona oluhlanganisa isisu luyandisa ingozi, njengasendabeni ye-gastritis UHelicobacter PyloriUmdlavuza wesisu uhlotshaniswa nokusetshenziswa, kokudla okunosawoti, okubhemayo noma okufakwe emanzini anosawoti, nokudla okuncane kwezithelo nemifino, kanye nokubhema.

Evolution

Umdlavuza wesisu owengeziwe uhlonzwe kusenesikhathi, angcono amathuba okuba alulame. Uma isanqunyelwe olwelweni lwesisu, abangaphezu kuka-50% abathintekayo bayophila iminyaka engaphezu kwengu-5. Uma isabalale ngohlelo lwe-lymphatic, izingqimba zemisipha, noma ezinye izitho, izinga lokusinda leminyaka emihlanu lingaphansi kuka-5%.

Ubani othintekayo?

Izehlakalo zayo azilingani. Emhlabeni wonke, umdlavuza wesisu uhlala uwu-2^st imbangela yokufa ngenxa yomdlavuza, kodwa yi-4^st imbangela eYurophu lapho isinciphe khona iminyaka engama-20. Lokhu kuncipha kwemvamisa kuthinta umdlavuza "wesisu esikude", i-antrum nomzimba. Ngokuthola "umdlavuza owandayo" we-cardia, lokhu kuyimpikiswano ngoba izifundo ezimbalwa ziphakamisa ukwanda kwesigameko.

Lo mdlavuza uvame kakhulu kubantu abanezimo zenhlalo-mnotho ezintekenteke, noma abathembele kakhulu secret futhi ukubhema ngoba ukulondolozwa kokudla. I-Japan, (1/1000 isakhamuzi,) I-China ne-Korea ziphakathi kwamazwe athinteke kakhulu.

E-France isigameko singu-12/100 kwabesilisa kanye no-000/4 kwabesifazane. Kwayi-100 bekunamacala amasha angu-000 ngonyaka. ECanada nase-United States, umdlavuza wesisu unjalo Okungajwayelekile. Sekuyancipha. Ngo-2009, yaba ngaphansi kwama-2% azo zonke izifo ezintsha zomdlavuza kubantu baseCanada.

Emazweni athuthukile, ukufaka iziqandisi kuye kwasiza ekunciphiseni izinga lomdlavuza wesisu.
