I-prostate-specific antigen (i-PSA) yinto ekhishwa ngamaseli e-prostate (ama-unit amancane ayisisekelo okusebenza e-prostate). I-PSA ibese isakaza egazini. Ngesikhathi segazini, i-PSA ingaxhunyaniswa namaprotheni akhona egazini noma angabanjwanga ("mahhala"). Kuyinto evamile ukuba kokubili i-PSA ifakwe futhi ikhululekile futhi ayikho enye yalezi zindlela ze-PSA ebhekwa njengejwayelekile.
I-PSA "engenamaphesenti-mahhala" ingabalwa ngokuhlukanisa inani le "PSA yamahhala" yi- PSA yenani eliphelele.
Ucwaningo luye lwabona ukuthi, ngokuvamile, abantu abanesifo somdlavuza we-prostate banamazinga aphansi e-PSA yamahhala uma kuqhathaniswa namadoda ngaphandle komdlavuza we-prostate.
I-PSA engavamile futhi engavamile yama-PSA
Ngokuvamile, amadoda anePSA engenamaphesenti angenayo amaphesenti angaphezu kwangu-25. Phakathi kwamaphesenti ayishumi namaphesenti angu-25 kubhekwa njengesizinda esiphakathi futhi ngaphansi kwamaphesenti angu-10 kubhekwa njengento ephansi.
Kodwa-ke, i-PSA engenamaphesenti ephansi, ngisho ne-PSA yezinga eliphakeme (inombolo encane owatshelwa ngayo inombolo yakho ye-PSA), akusho ukuthi unomdlavuza wesicathulo . Kuphela i- biopsy ingakwazi ukuthola ukuthi umdlavuza we-prostate ungakanani .
Ingabe I-PSA Yami EmaPentimenti Angasho Ngempela Noma Yimuphi?
Isimo esivame kakhulu lapho i-PSA engenamaphesenti engasetshenziselwa ukwenza isinqumo mayelana nendlela yokuhlola noma yokuphatha umdlavuza we-prostate yilapho izinga le-PSA eliphelele lizinga eliphakathi.
Kulesi simo, udokotela angancoma ukuthi umuntu abe ne-PSA ephansi-engenayo i-PSA (ngakho-ke ingozi ephakeme kakhulu yomdlavuza) futhi uncoma ngokumelene ne-biopsy kumuntu one-PSA engenamaphesenti aphezulu (ngaphezulu kuka-25 amaphesenti).
Umqondo Omusha Okuhlobene Njalo
Esikhathini esidlule, odokotela bathembele cishe kuphela ezingeni eliphelele le-PSA ukunquma ukuthi kungenzeka kangakanani ukuthi ube nomdlavuza wesicathulo.
Ngokushesha, kwacaca ukuthi ukusebenzisa i-PSA level ngokuphelele kuhlulekile ngezindlela ezithile ezibalulekile.
Ngesinye, amadoda athile ajwayelekile noma aphansi kakhulu e-PSA amazinga atholakale enomdlavuza wesicathulo. Okwesibili, amadoda amaningi anamazinga aphezulu e- PSA ayenayo umdlavuza wesicathulo. Esikhundleni salokho, banesimo esiyingozi kakhulu njenge- benign prostatic hyperplasia (BPH) .
Ngokuyinhloko, izinga le-PSA eliphelele alisho njalo indaba. Odokotela sebeqale ukusebenzisa izilinganiso ezihlukile ze- PSA ezifana ne- PSA ye - PSA kanye ne-PSA engenamaphesenti mahhala ukwenza izinqumo ezingcono mayelana nomngcipheko womuntu wesifo somdlavuza we-prostate.
