Prostate-specific antigen (PSA) chinhu chinogadzirwa nema prostate masero (madiki mashomanana ekushanda anoshanda e prostate). IPSA inotenderera inopa ropa. Iyo iri muropa, PSA inogona kuiswa kune mapuroteni aripo muropa kana kuti inogona kunge isina kushamwaridzana ("pasina"). Zvinowanzoitika kuti zvose zvakabatanidzwa uye pachena PSA uye hapana yeiyo mapepa ePSA inofungidzirwa kusina kujairika.
Izvo "chikamu-isina" PSA inogona kuverengwa nekuparadzanisa chikamu che "free" PSA nePSA yakazara.
Zvidzidzo zvakawana kuti, kazhinji, varume vane kenza yeprotate vane madiki mashoma ePSA pasina kana vachienzaniswa nevarume vasina kenza yeprotate.
Kazhinji uye Zvikamu Zvisina Kunaka-PSA isina
Kazhinji, varume vane peresenti-isina PSA iri pamusoro pe25 muzana. Pakati pe10 muzana uye 25 muzana inonzi inongorori yepakati uye pasi pe10 muzana inofungidzirwa kuva yakaderera.
Kunyange zvakadaro, iyo yakaderera-isina PSA isina, kunyange yakabatana nepamusoro-soro yePSA level (iyo nhamba yakasvibiswa yawakamboudzwa ndiyo yako PSA nhamba), hazvirevi kuti une kenza yeprostate . Bhiopsy chete inogona kunyatsoongorora chirwere chepirate .
MaPcent My-PSA Yakasununguka Anoreva Zvechokwadi Here?
Mamiriro ezvinhu akajairika umo muzana-isina PSA isina kushandiswa kuita sarudzo pamusoro pokuti ungaedza sei kana kurapa kenza yeprostate ndeye apo iyo PSA yakazara iri pamwero wepakati.
Mune mamiriro ezvinhu, chiremba angarumbidza hutano kumunhu ane huwandu hushoma-husina PSA (uye naizvozvo huwandu hwepamusoro hwekenza) uye anokurudzira kurwisa bhiopsy mumurume ane zvakakwirira-pasina PSA (pamusoro pe 25 purogiramu).
Rimwe Rinofananidzwa Nutsva
Munguva yakapfuura, vanachiremba vakatenderera zvakangoita padzidziso yakakwana yePSA kuti vasarudze kuti ungangodaro wava nekenza yeprostate.
Nokukurumidza, zvisinei, zvakava pachena kuti kushandisa chete PSA yakakwana yakakundikana mune dzimwe nzira dzinokosha.
Kune imwe, vamwe varume vane tsika dzakashata kana kunyange dzakaderera pasi dzePSA vakawanikwa vane kenza yeprostate. Chechipiri, varume vakawanda vane maPSA akakwana kwazvo vane kenza ye prostate. Panzvimbo pezvo, vane mamiriro ezvinhu akawandisa zvakadai sebenign prostatic hyperplasia (BPH) .
Chaizvoizvo, mhedziso yePSA yakazara haisi nguva dzose inotaura nyaya yose. Vanachiremba vakatanga iko kushandisa zviyero zvakasiyana zvePSA zvakadai sePSA density uye yePesti isina-free PSA kuita zvisarudzo zviri nani pamusoro pengozi yemurume wekenza yeprostate.
