Umdlavuza wesibini wesiqalo ubhekisela kubukho bomhlaza wesibini ongathandabuzekiyo ovela kumntu oye waba nomnye umhlaza nanini na ngaphambili. Le nto ingaba lixesha elididekayo, kuba ngokuqhelekileyo ukuba umhlaza ufunyanwa emva kokuba unomdlavuza, kungenxa yokusasazeka okanye imetastasis yomdla wokuqala, mhlawumbi kwindawo (kufuphi ne-tumor) okanye kwenye indawo yomzimba.
Isiganeko
Akwacaci ukuba kaninzi kangakanani ukwenziwa komhlaza wesiqhelo wesibini. Kunokucingwa ukuba nayiphi na into eyenza umhlaza omnye, unokukubeka phambili ukuvelisa omnye umhlaza esikhathini esizayo. Siyazi nokuba ezinye iindlela zokwelapha umdlavuza, ezifana ne-chemotherapy kunye neyeza zonyango, zinganyusa umngcipheko wokuba uhlakulele omnye umhlaza ongathandaniyo kwixesha elizayo. (Gcina ukhumbule ukuba lo mngcipheko uphantsi kakhulu, ngakumbi xa kuthelekiswa neenzuzo zokunyanga umhlaza wokuqala.)
Umdlavuza wesibini wesiqalo unokuvela kwimizimba efanayo okanye umzimba njengomhlaza wokuqala okanye kwenye indawo yomzimba.
Umzekelo wesifo somhlaza wesibili esisisigxina sinokubandakanya umdlavuza wesifuba esisekunene kumntu owayesenomdla wesifo somhlaza wesibeleko sekhohlo. Omnye umzekelo uya kuba ngumhlaza omtsha ongahambelananga ovela kwenye i-lobe yemiphunga, emva kokuhlinzwa ngokuphumelelayo ukususa umhlaza kwi-lobe eyahlukileyo.
U mzekelo
Imizekelo yesibini yomhlaza wesiqhelo ovela kwelinye iqumrhu ingaquka umdlavuza wamaphaphu (oqulethwe ngamangqamuzana omhlaza omhlaza kunye namaseli omhlaza wesifuba) kwiminyaka emva kokuba uphathwe ngumhlaza wesibele . Iiseli zomhlaza wesibini oogqirha babheka ngaphantsi kwe-microscope ziya kubonakala zibe ngumhlaza wesifo somhlaza kunye neeseli zomhlaza zesifuba.
Ngokufanayo, abanye abantu bangaphathwa ngempumelelo ngemhlaza yomphunga, kunye neenyanga okanye iminyaka kamva bavelise umdlavuza webele okanye umhlaza wesibeletho .
Oko kwathiwa, iyeza alisiyo isayensi epheleleyo, kwaye akunakwenzeka njalo ukuba ukwazi ukuba umhlaza omtsha ungumntu ohlukeneyo okanye unxulumene nomhlaza owawube nawo ngaphambili.
