Rak genining ozgurushi burun oylighandin kop murekkep bolushi mumkin. Bedende rakning peyda bolushi bedendiki normal hujeyrilerning gen alahidiligini ozgertish (mutation) bilen munasiwetlik bolup, burun oxshash bir rak osmisidiki rak hujeyrilining gen alahidiligi oxshash dep qaralghan, we shu alahidilikke asasen genge qartilghan dorilar bilen rak kisilige qarita dawalash ilip birilghan bolsimu, rak kisilining dawalash unumi yenila umut qilghandek yaxshi bolmay kelgen idi. Yiqinda tetqiqatchilar rak osmisining oxshimighan jayliridin ornek ilip tekshurush ilip barghanda, oxshimighan ornektiki rak hujeyrilerning gen alahidilikining oxshash emeslikini bayqighan. Bu rak kisilining dawalash unimining yaxshi bolmasliqining muhim bir sewepi bolushi mumkin.
