Umdlavuza wamaphaphu
Incazelo emfushane:
Umdlavuza wamaphaphu (owaziwa nangokuthi umdlavuza we-bronchial) umdlavuza wamaphaphu omubi obangelwa izicubu ze-bronchial epithelial zezinga elihlukile.Ngokubukeka, ihlukaniswe phakathi, i-peripheral kanye nenkulu (okuxubile).
I-Epidemiology
Umdlavuza wamaphaphu yithumba eliyingozi elivame kakhulu futhi yimbangela evame kakhulu yokufa komdlavuza emazweni asethuthukile.Ngokwemininingwane ye-International Cancer Research Institute, babalelwa esigidini izigameko ezintsha zomdlavuza wamaphaphu emhlabeni minyaka yonke, kanti u-60% weziguli ezinomdlavuza zibulawa umdlavuza wamaphaphu.
E-Russia, umdlavuza wamaphaphu usezingeni lokuqala phakathi kwezifo zesimila, ezibalelwa ku-12% walesi sifo, futhi utholakala njengomdlavuza wamaphaphu kuma-15% eziguli ezifile.Amadoda anenani eliphezulu lomdlavuza wamaphaphu.Isimila esisodwa kuzo zonke ezine eziyingozi emadodeni umdlavuza wamaphaphu, kanti esisodwa kuzo zonke izimila eziyishumi nambili kwabesifazane umdlavuza wamaphaphu.Ngo-2000, umdlavuza wamaphaphu wabulala amaphesenti angama-32 amadoda kwathi u-7.2% wabesifazane watholakala benezimila eziyingozi.
