Baarayaasha machadka Wellcome Sanger ee jaamacada College ee London, UK, ayaa daraasad ay ku sameeyeen dadka sigaarka cabayay sanado badan waxayna ogaadeen ka dib markay joojiyeen, in unugyada caafimaadka qaba ee sanbabada dadkan ay tarmeen, yareynta dhaawacyada ka dhasha sigaar cabida halista ka dhalata kansarka sanbabada.

Markii hore, horay ayaa loo ogaa in joojinta sigaarku ay joojiso isbeddelada hidde-wadaha ee sababa kansarka sanbabada, laakiin cilmi-baaristaan ​​cusub waxay keeneysaa natiijooyin wax ku ool ah oo ku saabsan joojinta sigaarka, taasoo muujineysa awoodda dib-u-cusbooneysiinta ee unugyada sambabka markii ay sigaar u baaba'aan.

Sidee daraasadda loo qabtay

Baarayaasha Jaamacada Kuleejka ee London, oo mas'uul ka ah machad daraasad ku sameeya hiddo-wadaha iyo hiddo-wadaha aadanaha, iyagoo raadinaya inay fahmaan waxa ku dhaca unugyada sambabka markay sigaarka la kulmaan, waxay sameeyeen daraasad ay ku falanqeeyeen is-beddelka unugyada ee hawo-mareenka 16 qof, kuwaas oo ay ka mid ahaayeen dadka sigaarka caba, kuwii hore ee sigaar cabi jiray iyo dadka aan waligood sigaar cabbin, oo ay ku jiraan carruurta.

Si loo sameeyo gorfaynta daraasadda, cilmi baarayaashu waxay unugyo ka soo ururiyeen sambabaha dadkan iyagoo ku samaynaya dheecaan ka-qaadis ah ama burushka burushka ah ee loo yaqaan 'bronchoscopy', oo ah baadhitaan lagu qiimeeyo marin-haweedyada iyadoo afka laga soo saarayo tuubo jilicsan. astaamaha hidaha iyadoo la fulinayo taxanaha DNA ee unugyada goostay.

Maxay daraasadu muujisay

U fiirsashada shaybaarka ka dib, cilmi baarayaashu waxay ogaadeen in unugyada caafimaadka qaba ee sambabaha dadka joojiyay sigaarka ay afar laab ka badan yihiin kuwa wali isticmaala sigaarka maalin kasta, tirada unugyadani waxay u dhowdahay kuwa laga helo dadka aan waligood sigaar cabbay.

Sidaa darteed, natiijooyinka daraasaddan ayaa muujisay in markii ay u sii dheeraan waayaan tubaakada, unugyada sambabka ee caafimaadka qaba ay awoodaan inay cusboonaysiiyaan unugyada sambabka iyo dahaadhka hawo-mareenka, xitaa dadka cabba baakad sigaar ah maalintii muddo 40 sano ah. Intaa waxaa dheer, waxaa suurtagal ahayd in la aqoonsado in cusbooneysiinta unugani ay awood u leedahay inay ka ilaaliso sambabka kansarka.

Maxaa hore loo ogaa

Daraasado hore ayaa horey u muujiyey in sigaar cabista ay sababto kansarka sanbabada, maadaama ay keento caabuq, caabuqyo ayna yaraato difaac, taasoo keenta isbadal ku dhaca unugyada sambabaha. Si kastaba ha noqotee, markaad joojiso sigaar cabista, isbeddeladan unugyada waxyeellada leh waa la hakinayaa oo halista ah inuu ku dhaco kansarka sanbabada ayaa si aad ah hoos ugu dhacday.

Saameyntan wax ku oolka ah ee joojinta sigaarka waxaa loo arkaa isla markiiba isla markaana horumar la taaban karo ayaa ku soo kordhay muddadii aad joojisay sigaarka, xitaa dadka da'da dhexe ee sigaarka caba sannado badan. Daraasaddan cusubi waxay sii xoojisay gabagabadaas, laakiin waxay keeneysaa natiijooyin cusub oo dhiirrigelin ah oo ku saabsan muhiimadda ay leedahay joojinta sigaar cabidda, oo muujineysa awoodda sanbabada ee dib ugu soo nooleynta joojinta tubaakada.
