Khansara yoyamba imatchedwa malo oyambirira (chiwalo kapena minofu) kumene khansa inayamba.
Mwachitsanzo, khansa yochokera m'mapapu imatchedwa kansa ya m'mapapo . Ngati khansara yamapapu imafalikira ku ubongo, iyo imatchedwa kansa ya mapaipi yamaphunziro oyambirira ku ubongo. Mosiyana ndi zimenezi, khansara yomwe imayambira m'mawere ndi kufalikira m'mapapu imatchedwa primary primary cancer m'matumbo.
Khansa yachiwiri kapena yachiwiri
Nthawi zina khansa yachiwiri ndi yachiwiri imagwiritsidwa ntchito mosiyana koma ingatanthauze zinthu zosiyana. Mawu akuti khansa yachiwiri angatanthawuze za masastasis a khansa yapachiyambi, kapena khansara yachiŵiri yosagwirizana ndi khansa yapachiyambi. Pamene mawu akuti kansa yachiwiri amagwiritsidwa ntchito, nthawi zambiri amatanthauza khansara yachiwiri yoyamba, mwachitsanzo, khansara yosiyana ndi khansa yoyamba, yomwe imachokera ku chiwalo china kapena minofu.
Izi zingakhale zosokoneza ngati mukumva kuti khansa yachiwiri ikhoza kuchitika chifukwa cha chithandizo cha khansa yoyamba. Mankhwala enaake okhudza mankhwala a chemotherapy, komanso mankhwala othandizira odwala, amachititsa kuti DNA iwononge DNA pamene ikulimbana ndi khansa. Izi zikachitika chiwombankhanga chatsopano chimatchedwa khansara yachiwiri yoyamba.
Kansa ya Chiyambi Chosaidziwika
Nthawi zina, malo oyambirira omwe khansa imayambira sadziwika. Ena khansa amapezeka pokhapokha atafalikira kumadera osiyanasiyana a thupi, kuphatikizapo mapapo.
Pachifukwa ichi, chotupacho chikanatchedwa kansa ya metastatic yosadziwika. Ndili ndi mayesero opatsirana opatsirana komanso opaleshoni ya maselo, matenda a kansa osadziwika amapezeka mochepa kuposa kale, koma izi zimachitikabe. Chifukwa chake kawirikawiri chifukwa chotupa ndi "opandafferentiated." Maselo a kansa amatha kusiyana kwambiri ndi maselo obadwa , nthawi zina amawapangitsa kukhala osadziwika bwino pogwiritsa ntchito microscope.
Ngakhale malo amodzi omwe sangathe kudziwika ndi khansa, adokotala amathabe kuchiza khansa. Akuti 2 mpaka 5 peresenti ya odwala khansa ali ndi mavitamini omwe malo oyambirira sangathe kudziwika.
Khansa sikuti nthawi zonse ili ndi malo oyambirira. Chitsanzo cha izi ndi lymphoma. Komabe pamene malo oyamba omwe amayamba kutchedwa lymphoma sichidziwike, sali ngati khansara ya chiyambi chosadziwika.
