Dhibaatooyinka Dhibaatooyinka Qaadanaayo

Ma jiro nooc ka mid ah faayraska sababaya kansar. Lixda fayras oo kala duwan oo sababi kara kansar ayaa ka yimaada qoysaska fayrasta kala duwan, waxay leeyihiin kala duwanaansho, waxayna leeyihiin wareegyo nololeed oo kala duwan.

Guud ahaan, infekshan kasta oo ka mid ah fayruusyadaasi aad ayuu u badan yahay. Nasiib wanaag, kaliya dad tiro yar oo dadka qaba infekshankan waligoodba waxay sii wataan kansarka. Haddii kansarku sii kordho, waxay qaadan doontaa sanado ama xitaa tobanaan sano si ay u qabtaan. Waxaa intaa dheer, fayrusyada iyaga u gaar ah kuma filna inay keenaan kansar waana inay sidoo kale raacaan difaaca jidhka, isbeddellada gawaarida, saameeynta hidaha, iyo soo-saarka kansarka.

Halkan waxaa ku yaal lix nooc oo fayruusyo ah oo keena kansar (aka fayruska curyaamiya):

Hepatitis C

Cagaarshowga C waa fayruska RNA. Waxay sababtaa cagaarshow ba'an iyo mid daba-dheer. Caabuqa joogtada ah ee cagaarshow C wuxuu keenaa cirrhosis ama cirridka beerka. Boqolkiiba 1 ilaa 2 dadka cudurka qaba, cudurka cirrhosis wuxuu ugu dambeyn keeni karaa kansarka hepatocellular (beerka). Cagaarshowga C waxaa kale oo lala xiriiriyaa lymphoma aan ahayn Hodgkin .

Inkastoo cilmi-baarayaashu aysan wali sameynin tallaal cagaarshow C, daaweynta waxtarka leh ee cudurku ku jiro, oo ay ku jiraan Olysio, Sovaldi, iyo Harvoni .

3 -

Hepatitis B

Halka cagaarshowga C waa fayruska RNA, Cagaarshow B waa fayrus DNA ah. Inkasta oo uu jiro nooc kale oo fayras ah, cagaarshowga B wuxuu keenaa infekshin leh koorso daaweyn ah oo la mid ah cagaarshow C: Cagaarshow ba'an iyo diiqad, cirrhosis, iyo kansarka hepatocellular.

Kansarka Hepatocellular waa kansar gardarro ah oo dila sannad ama laba sano ka dib caabuqa. Daaweynta kansarka hepatocellular waxay ku dhalataa qalliinka dheecaanka beerka ama beerka beerka.

Nasiib wanaag waxaan haynaa tallaal cagaarshow B.

4 -

Human Papilloma Virus (HPV)

HPV waa fayras yar oo DNA ah oo keena burooyinka xubnaha taranka. Caabuqa dib-u-dhaca ee leh shuban-sare ee HPV wuxuu keeni karaa kansarka afka ilmo-galeenka. Waxaa intaa dheer, infekshanka HPV ee joogtada ah ayaa sidoo kale lagu soo koobay horumarinta noocyada kale ee kansar, oo ay ku jiraan buro madaxa iyo qoorta, kansarka maqaarka ee bukaanka difaaca jirka (ka fikir AIDS), iyo kansarrada laf dhabarta ah.

Nasiib wanaag, thanks to smear PAP, waxaan leenahay baaritaanka hore ee kansarka ilma-mareenka.

Virus Nooca Nafaqada Xanuunka Bini'aadamka (1) (HTLV-1)

HTLV-1 waa retrovirus RNA. Dunida adduunka, 5 ilaa 25 milyan oo qof ayaa ku dhacda fayraskan; Si kastaba ha ahaatee, keliya dad tiro yar (5 boqolkiiba) ayaa ka muuqda calaamadaha. HTLV-1 wuxuu leeyahay tropism ama soo jiidasho unugyada CD4, unugyada lafa-leukemia. Labaatan iyo soddon sano kadib infekshanka HTLV-1, qaaxada T-cell ee qaangaarka ah ayaa kobcin kara.

Chemotherapy ayaa markii hore la isticmaali karaa si loogu daaweeyo qaaxada T-cell-ka qaan-gaarka ah waxayna natiijooyinka ku-soo-shubidda mudada gaaban ku xigtaa dib-u-dhicid degdeg ah oo cudurka ah. Waqtiga uurka (dhexdhexaadinta) ee ka danbeeya kobaca ka dib horumarinta qaaxada T-cell ee qaangaarka ah waa 8 bilood.

6 -

Epstein-Barr Virus

EBV waa fayruus ku-meel-gaadh ah oo aan dhammaanteen naqaanno-wuxuu keenaa mononucleosis . Inkasta oo 95% dadku ay ku jiraan EBV on dhaqanka cunaha, badankood infekshanku waa kuwo hooseeya, iyada oo tiro yar oo dadka ka mid ah ay kobcinayaan cudurada bukaan-socodka.

EBV waxaa lala xiriiriyay kansar kala duwan oo ay ka mid yihiin B- iyo T-cell lymphomas, leiomyosarcomas, kansarka naasofalengeal kansarka, cudurka Hodgkin, iyo cudurada lymphoproliferative kadib.

7 -

HHV-8 ama Kaposi Sarcoma Herpesvirus

Sanadkii 1994, HHV-8, ama Kaposi sarcoma herpesvirus, ayaa lagu soo bandhigay horumarinta Kaposi's sarcoma , kansar kaas oo sababa xanuunada maqaarka iyo afka oo ku dhaca AIDS-ka. Si kastaba ha noqotee, kuwa leh nidaamyada difaaca jirka ee xooggan, HHV-8 marar dhif ah ayaa haya.

Tilmaamaha mustaqbalka ee loo yaqaan "Viruses Tumor"

Hababka daaweynta ee novel ee kansarka ay sababtay fayrusyada burooyinka bini-aadamka waxay diiradda saaraan badeecooyinka hargabka ee viral oo gaar u ah unugyada burooyinka ee uu keeno fayraska. Iyadoo lagu kobcinayo daaweynyo si gaar ah loogu bartilmaameedsado unugyada infekshanku ku dhacay, fursadaha daaweynta mustaqbalka waxay ku dari karaan unugyada caafimaad ee jirka. Waqtigaan, daaweynta sida daaweynta kiimikada iyo daaweynta shucaacada ayaa dila dhammaan unugyada, kuwaas oo sharxaya dhibaatooyinkooda xun ee xun.

Waqtigaan, habka ugu wanaagsan ee looga hortagi karo kansarka ee ku dhaca fayruusyada burooyinka bini-aadamka (si kastaba ha ahaatee nadir) waa in laga hortago khatarta fayrusyada burooyinka bini-aadamka. Inkasta oo qaar ka mid ah fayruusyadani ay ku jiraan meel kasta, waxaan ka hortagi karnaa inay soo gaadhaan qaar ka mid ah fayrasyada sida cagaarshow B iyo C. Waxaa kale oo jira tallaal cagaarshow B iyo HPV.
