Chibadwa sangathe kulimbana ndi Cancer

Maselo ena pafupifupi kubereka pamene ena M'malo mwake, pa breakneck mayendedwe. Maselo ena lekani mankhwala amphamvu, pamene ena m'malo mwake - yomweyo kufa. Koma mulimonse, maselo amenewa ali wapangidwa jini chomwecho chimene asayansi kuziphunzira momwe angathetsere kuti kuchiza matenda monga khansa.

Ndicho chimaliziro kuonekera mu magazini otchuka Science kuti olemba kuphunzira ndi kufotokoza kuti panthawi imeneyi chitukuko cha mankhwala, asayansi ayi koma anatha kupereka dziko mankhwala a khansa ndipo amati mankhwala akamagwira chibadwa sadzatha kugonjetsa matendawa.

Ngati kapena ayi, ndi matupi a khansa atha kufotokozera njira zothetsera vutoli. Koma phunziro la amaona kuti njira zothetsera vutoli sanama mu ndege ya DNA matendawa. mankhwala Current cholinga kudziwa maselo amene amakhalapo chifukwa masinthidwe anayamba mosatonthozeka nawo. Iwo likukhalira kuti basi ayenera kupeza mamolekyulu amene ali ndi udindo kusintha kenako mankhwala kupeza mankhwala kuti adzakhala kupirira zinthu zimenezi matenda.

Kuchokera pa ichi, monga mankhwala Xalkori Pfizer (m'mapapo khansa) ndi Gleevec Novartis (aakulu myeloid khansa). Koma pali mavuto ena, nthawi (ndipo kawirikawiri amabwera) pamene mankhwala anasiya ntchito, monga ulamuliro, mu Zikatero amaganiza kuti maselo a khansa zidapatsa ndi kusintha kwa watsopano, umene mankhwala chabe mphamvu.

Mu phunziro limeneli, ofufuza anadabwa kupeza kuti maselo m'matumbo khansa zinthu zosiyana kwambiri, ngakhale kuti poyamba anali ofanana ndi masinthidwe anali ndi kumverera kusiyana kumeneku analibe kusiyana kulikonse. Izi zinali zosemphana ndi chikhulupiriro institutionalized alipo kuti chibadwa ali ndi udindo ntchito za maselo munthu mu chotupa, ndi kwa kwambiri ntchito kuswana ndi kubvomereza kwawo kwa mankhwala amphamvu.

Monga zachibadwa ndi Dzhon Dik limati analemba za kafukufukuyo, ngati DNA ndi - si ndiyekhayo chitukuko chotupa, ife tikhoza kuganiza kuti ngati mukufuna kuchiza khansa, ndizofunika mankhwala, zomwe zikhazikitsidwe makhalidwe si chibadwa.

Popanda kupita tsatanetsatane wa phunziro, tiona kuti asayansi anali kwenikweni kudabwa ndi khalidwe la zotupa khansa mu m'matumbo. Monga anachita kwa mankhwala analipo maselo a khansa zinthu zofanana sizimadziwika.

asayansi ena ndi akatswiri kutamandidwa kafukufuku ndi kuthandiza kuganiza kuti munthu khansa mankhwala - ndi bobble chachikulu, makamaka mukamawerenga mawonekedwe mu umene anapereka kwa anthu.

Ena amakhulupirira kuti chifukwa anali kuchitika, chifukwa kukula kwa maselo a khansa amadalira magawo ambiri kunja, kuphatikizapo Mwachitsanzo, chilengedwe, ndipo iwo adzakhala mmodzi mwa zinthu zoopsa, imene mapeto isonyeza mmene kukhala mankhwala agwire ntchito mankhwala a khansa.

Ochita kafukufuku amakhulupirira kuti chifukwa ndi: mu gawo limene selo ndi (zina, magawano, kukula); mu majini amene ali nawo nthawi ina; ngati pali mwayi kwa mpweya wa khungu makamaka, ndi zinthu zina sanali chibadwa.

Mwachitsanzo, mankhwala zikhoza kuti selo kusintha kuchokera matalala gawo kafalitsidwe gawo, monga iwo kukhala osatetezeka kwambiri ku mankhwala amphamvu, omwe mfundo ukuperekedwa maselo bystrorazmnozhayuschiesya.

Asayansi akukhulupirira kuti khansa ayenera kuchizidwa achire pa mlingo maselo.
