Chizoloŵezi chosazolowereka cha khansa chimakhala ndi zotsatira zovuta kwambiri
Ngakhale kuti khansa ya khansa yamtunduwu imakhala yachilendo, zimatha kuchitika ngati khansara imafalikira (kutaya thupi) kuchokera ku chotupa pa khungu kapena kubwerera kwa munthu yemwe adachiritsidwa kale.
Zikuoneka kuti osachepera awiri peresenti ya khansa yapadera ndi zotsatira za melanoma. Komabe, zikachitika, nthawi zambiri zimakhala zowawa komanso zovuta kwambiri.
Pa nthawi yomweyo, chifukwa ndizosazolowereka, khansa ya mtundu uwu imangowonongeka mosavuta panthawi yoyamba komanso yotsatiridwa.
Khansa Yachikondi Yachiwiri ya Anthu Amene Ali ndi Melanoma
Pamene mankhwala a metastasis akukhudzidwa, khansa ya khansa imatengedwa ngati "khansa yapachiyambi" pamene ziwalo zina zomwe zimakhudzidwa ndi kufalikira kwa khansa ya khansa imakhala "yachiwiri".
Kachilombo ka khansa yachiwiri yofiira kwambiri imachokera ku mitundu ya maselo omwe amagwidwa ndi khansa ya melanoma. Melanoma imachokera ku mtundu wapadera wa selo, wotchedwa melanocyte , umene umatipatsa khungu ndi maso mtundu wawo.
Pa 96 peresenti ya matenda, khansa ya khansa ya khansa imachokera pakhungu. Zingathe kusokoneza mitsempha yambiri komanso kuzifalitsa m'thupi lonse. Kawiri kawiri, zidzakhala ziwalo zosakhala ndi khungu zomwe zimakhala ndi melanocyte zomwe zimakhudza kwambiri. Izi zimaphatikizapo maso ndi minofu ya mucosal ya pakamwa, mphuno, anus, rectum, ndi vagin.
Momwemonso, rectum imakhudzidwa kwambiri ndi mitsempha ya khansa ya khansa yapamtunda (yomwe ili ndi ma melanocytes ochepa).
Pomwe zikunenedwa, zotupa zosautsa zidzatha "kulumikiza" minofu yapafupi ndipo, pochita izi, zimathandiza kufalitsa khansara ku rectum ndi / kapena anus ku colon pafupi.
Gulu limodzi lomwe liri pangozi ya khansa yachiwiri kapena khansa ya m'magazi ndi anthu omwe ali ndi HIV . Mosiyana ndi zimenezi, chiwerengero cha khansa yapakhungu kapena chigoba chachikulu sichitha kuonedwa ngati chowopsa.
Kansa Yachiwiri M'malo Opangidwa ndi Melanoma Yopwetekedwa
Mosiyana ndi khansa yachiwiri, matenda amodzi omwe amayamba pambuyo pochiza khansa imaonedwa ngati " khansa yachiwiri " (khansa yachiwiri yapakati). Ngakhale khansara yachiwiri ndi "yatsopano" ndipo siyinayanjane ndi yoyamba, maonekedwe ake nthawi zambiri amagwirizanitsidwa ndi zomwe zimayambitsa khansa poyamba.
Kuchiritsidwa bwino kwa khansa ya khansa sikuyenera kutanthauza kuti simungapeze mitundu ina ya khansa. Momwe mwakhala muli ndi melanoma imakupangitsani inu pachiopsezo chachikulu. Ma khansa achiwiri angaphatikizepo khansa yapakhungu yomwe sagwirizana ndi yoyamba, ndipo, motere, silingaganizidwe kuti ikubwereranso kapena kubwereranso.
Mankhwala ena achiwiri omwe amawonedwa kale ndi anthu omwe amachitiridwa khansa ya khansa ndi awa:
- khansa ya m'mawere
- khansa ya impso
- non-Hodgkin lymphoma (NHL)
- kansa ya prostate
- khansara yamatenda
- khansara yofewa
- khansara ya m'mimba
- khansa ya chithokomiro
Khansara yeniyeni, mosiyanitsa, sichikuwoneka mmwamba kuposa momwe mungayembekezere anthu ambiri.
Kukhala ndi Moyo ndi Nthawi Zopulumuka
Khansa yachiwiri yamtunduwu pamtundu wa khansa ya khansa imagwirizanitsidwa ndi nthawi yayitali (pafupifupi miyezi 10) chifukwa chodziwika bwino kuti nthawi yayitali yodwala matendawa. Malinga ndi kafukufuku wochokera ku chipatala cha Mayo, nthawi yochepa pakati pa matenda a melanoma ndi khansa yachiwiri ya colon inali zaka 7.47 zodabwitsa.
Pakati pa odwala anaphunzira, kuchotsa opaleshoni ya khansara kunawonekera kwa nthawi yayitali ya moyo kuchokera kwa miyezi isanu ndi iwiri mpaka kufika pa 27.
