Igama lomdlavuza wesibili lingasetshenziselwa ukubhekisela kumdlavuza wesibili oyinhloko noma kumdlavuza osakazekile kusuka kwenye ingxenye yomzimba kuya komunye ( umdlavuza wemetastatic ).
Kule ngxoxo, ngeke sikhulume ngomdlavuza we-metastatic, kodwa umdlavuza wesibili kuphela.
Izinhlobo
Kubalulekile ukwenza esinye isihlukaniso namagciwane wesibili. Uma othile eba nomdlavuza wesibili kungaba ngezizathu ezimbalwa.
Enye, futhi esizoxoxa ngakho lapha ngumdlavuza wesibili ophumela ngenxa yemiphumela yomdlavuza eyenza umdlavuza.
Enye indlela umdlavuza wesibili noma umdlavuza wesibili oyisiqalo ngezinye izikhathi osetshenziswa ngayo uma umuntu eba nomdlavuza wesibili - kungaba endaweni yomdlavuza wokuqala noma kwenye indawo - engahlobene nemithi yomdlavuza wokuqala. Lezi zijwayele kakhulu ukuthi noma yikuphi umuntu okhethwe ngumdlavuza ekuqaleni kungase kube nesibopho sokuthuthukiswa komdlavuza wesibili kamuva. Lokhu kubizwa ngokuthi umqondo "wezinto ezibangelwa ubungozi."
Okuhlobene ne-Cancer Treatment Previous
Amagciwane wesibili ahlobene nemithi evela kumdlavuza wangaphambili awavamile, kodwa ngokuqinisekile, kwenzeka. Siyazi ukuthi izidakamizwa eziningi ze-chemotherapy, ngaphezu kokubulala amangqamuzana omdlavuza, zinamandla okubangela umdlavuza ngokulimaza i-DNA kumaseli avamile. Kunjalo nange-radiation therapy.
Ukuze uqonde lokhu kungasiza ukukhuluma ngendlela yokwelashwa kwe-chemotherapy kanye nokwelashwa kwemisebe. Lezi zokwelapha zivame ukusebenza ngokubangela " ukulimala okwenketshezi " ekuphatheni kwezakhi zofuzo kumaseli. Isizathu esetshenziswa ngazo ngomdlavuza ukuthi amagciwane omdlavuza, ngokuvamile, ahlukanisa ngokushesha kunamaseli anempilo, ngakho-ke umonakalo ngaleyo ndlela kungenzeka ukuthi uvele emangqamuzaneni omdlavuza.
Igama elithi oxidative lisho ukuthi kwenzeka okwenzekayo okudinga ukuba khona kwe-oxygen.
Indlela yokuqhubeka nokuqonda lo monakalo - nokuqonda ukuthi umdlavuza ungaqala kanjani kokubili futhi uphendule imithi yomdlavuza, ukubuka lokhu kuphendula. Sizwa okuningi mayelana nama-antioxidants. Ama-antioxidants asebenza ngokuvimba lokhu kuphendula. Ngenxa yalesi sizathu, abantu bavame ukweluleka ukuba bagweme ama-antioxidants ngenkathi ukwelashwa umdlavuza - awufuni ukuvikela amangqamuzana omdlavuza emonakalweni.
Umonakalo we-chemotherapy kanye nokwelapha imisebe kungaphazamisa i-DNA yamaseli avamile. Ngokuhamba kwesikhathi, lo monakalo ungabangela ukuthi la maseli avamile abe amangqamuzana omdlavuza. Uma lokho kwenzeka omunye umdlavuza uqala.
Ngemuva kwe-Radiation Treatment
Saqala ukubona ubufakazi bomdlavuza wesibili kubantu abaye babhekwa ukwelashwa kwemisebe. Ingozi yomdlavuza wesibili emisebeni ixhomeke ku:
- Umthamo wemisebe
- Indawo idalulwe emisebeni
- Ubudala besiguli
Ingozi yamagciwane wesibili kusuka ekwelashweni kwama-radiation iyathuthuka njengoba kuncane "ukusabalalisa" ngamasu amasha kunamaqhinga amadala, okusho ukuthi izicubu ezincane zivezwe. Kulabo abakhathazekile bezwa lokhu ababenomdlavuza wesifuba, ingozi yomdlavuza wesibili kusukela ekwelashweni kweminye imithi emva kokuba i-mastectomy ikhulise ingozi, kodwa kubonakala sengathi ayikho ingozi ekhuphuka emithini yokwelashwa okunikezwa emva kwe-lumpectomy.
Ngemuva kweKhemotherapy
Amagciwane wesibeletho angase avele ngemva kwekhemotherapy, umdlavuza ovame kakhulu ube yi-leukemia. Izidakamizwa ezingase zidale i-leukemia zihlanganisa ama-alkylating agents, imithi ye-platinum, ne-topoisomerase inhibitors.
Ezinye izidakamizwa ezithintekayo zingakhuphula ingozi yokuthuthukisa umdlavuza wesibili.
Ngemuva kokwelashwa okulindelekile
Ezinye izidakamizwa ezithintekayo zingakhuphula ingozi yokuthuthukisa umdlavuza wesibili, ikakhulukazi lezo ezenzelwe ukuhlasela iphrotheni ye-BRAF.
Ngemuva kokuguquka kweStem Cell
Iziguli zokufakelwa kwesitembu se-Stem zinengozi enkulu yamagciwane wesibili. Lokhu kungahlotshaniswa kokubili imishanguzo kanye nemithi ephezulu yokwelapha i-chemotherapy ngaphambi kokufakelwa, kanye nezidakamizwa zokuzivikela ezidingekayo ukuvimbela ukwenqatshwa emva kokufakelwa.
