Umdlavuza wamaphaphu
Incazelo emfushane:
Umdlavuza wamaphaphu (owaziwa nangokuthi umdlavuza we-bronchial) umdlavuza wamaphaphu onobungozi obangelwa izicubu ze-epithelial ze-bronchial ezinezinga elihlukile. Ngokusho kokubukeka, uhlukaniswe phakathi kwezingxenye eziphakathi, ezingaphandle kanye nezinkulu (ezixubile).
I-Epidemiology
Umdlavuza wamaphaphu uyisimila esibi esivame kakhulu futhi uyimbangela evame kakhulu yokufa komdlavuza emazweni athuthukile. Ngokusho kwedatha ye-International Cancer Research Institute, kunezigameko ezintsha ezingaba yisigidi zomdlavuza wamaphaphu emhlabeni minyaka yonke, kanti ama-60% eziguli zomdlavuza ziyafa ngenxa yomdlavuza wamaphaphu.
ERussia, umdlavuza wamaphaphu ungowokuqala phakathi kwezifo zesimila, obangela u-12% walesi sifo, futhi utholakala njengomdlavuza wamaphaphu ku-15% weziguli zesimila ezifile. Amadoda anesilinganiso esiphezulu somdlavuza wamaphaphu. Isimila esisodwa kwezine ezibulalayo emadodeni siwumdlavuza wamaphaphu, kanti isimila esisodwa kweziyishumi nambili kwabesifazane siwumdlavuza wamaphaphu. Ngo-2000, umdlavuza wamaphaphu wabulala amadoda angu-32% kanti u-7.2% wabesifazane batholakala benesifo sezimila ezibulalayo.
