Monga momwe dzinali likusonyezera, khansa colorectal amapangidwa mu koloni kapena mu kachilomboka, gawo lomaliza la matumbo akulu.

Le khansa colorectal afika pa 3^e chiwerengero cha khansa yofala kwambiri ku Canada, mwa amuna ndi akazi. Mmodzi mwa amuna 14 aliwonse ndi 1 mwa amayi 15 aliwonse ali pachiwopsezo chokhala ndi khansa yapakhungu m'moyo wawo wonse.¹.

Khansara ya colorectal ndiyofala kwambiri m'maiko otukuka. Makhalidwe a moyo, makamakachakudya, komanso imagwira ntchito yofunika kwambiri pamawonekedwe ake. Mwachitsanzo, zimenezi zikufotokoza kuti anthu a ku Japan, amene amakhudzidwa pang’ono ndi khansa ya m’mimba ku Japan, amakhala ngati mmene anthu a ku America amachitira patatha zaka zingapo atasamukira ku United States n’kuyamba kutsatira zakudya zawo.

Anthu ena akhoza kuchipeza chifukwa cha cholowa chakutengera. Koma mu 75% ya milandu, cholowa sichimakhudzidwa.

Evolution

Le khansa colorectal zimatenga zaka zingapo kuti zipangidwe, monga makhansa ambiri. Nthawi zambiri amachita izi kuchokera tizilombo tating'onoting'ono m'mphepete mwa khoma mkati mwake koloni. Ma polyps ndi ang'onoang'ono, okhala ndi minofu. Pali mitundu ingapo. Nthawi zambiri, amakhala abwino. Komabe, zimadziwika kuti ena aiwo amatha kukhala ndi khansa. Zimatenga pafupifupi zaka 10 kuti polyp ipange chotupa cha khansa. Ma polyps (khansa kapena ayi) nthawi zina amayambitsa kusapeza bwino m'mimba. Kuti mumve zambiri, onani tsamba lathu la Intestinal Polyps.

Dokotala akangozindikira ma polyps mwa wodwala, amamuyesa kuti awone ngati angawononge thanzi lake.

Pakupita patsogolo, khansa ya m'matumbo imatha kufalikira zigawenga lymphatic, kenako ku chiwindi kenako ku ziwalo zina za thupi kupanga metastases.

Ku Canada, khansa yapakhungu ndiyo 2^e choyambitsa imfa ndi khansa. Chiwopsezo cha imfa zaka 5 pambuyo pa matenda ndi pafupifupi 40% mwa amuna ndi akazi.

Pakadali pano, opitilira theka la milandu amapezeka mwa anthu azaka 70 ndi kupitilira apo¹. Ogwira ntchito zachipatala akufuna kuti anthu ambiri ayezedwe kuwunika pafupipafupi, kuyambira zaka 50, komanso koyambirira kwa anthu omwe ali pachiwopsezo. Khansara yoyambirira imapezeka, ndipo ndizotheka kutero zizindikiro zisanabwere, mwayi wochuluka umakhala wabwino machiritso.

Nthawi yofunsira

Ngati muli ndi magazi mu chopondapo kapena kutsekula or kudzimbidwa Izi zikapitilira, ndikofunikira kukaonana ndi dokotala. Kwa omwe ali pachiwopsezo, ndikofunikira kuyezetsa magazi. Kambiranani izi ndi dokotala wanu.
