Kuyezetsa magazi kwa prostate-antigen (PSA)

Prostate-antigen (PSA) ndi puloteni yomwe imapangidwa ndi maselo a prostate.

Kuyesa kwa PSA kumachitika kuti zithandizire kuwunika ndikutsatira khansa ya prostate mwa amuna.

Muyenera kuyesa magazi.

Onetsetsani kuti wothandizira zaumoyo akudziwa mankhwala onse omwe mukumwa. Mankhwala ena amachititsa kuti PSA yanu ikhale yotsika kwambiri.

Nthawi zambiri, palibe njira zina zapadera zofunika kukonzekera mayesowa. Simuyenera kuyesedwa PSA mukangodwala matenda amkodzo kapena mukuchita opaleshoni kapena opaleshoni yokhudzana ndi kwamikodzo. Funsani omwe akukuthandizani kuti mudikire nthawi yayitali bwanji.

Mutha kumva kupweteka pang'ono kapena kubaya pobaya singano. Pambuyo pake, pakhoza kukhala kupunduka kapena kuvulala pang'ono. Izi posachedwa zimachoka.

Zifukwa zoyeserera PSA:

• Mayesowa atha kuchitidwa kuti awonetse khansa ya prostate.
• Amagwiritsidwanso ntchito kutsatira anthu atalandira chithandizo cha khansa ya prostate kuti awone ngati khansayo yabwerera.
• Ngati wopezayo akumva kuti prostate gland si yachilendo poyesedwa.

ZAMBIRI POPANDA KULANGALIRA khansa ya prostate

Kuyeza kuchuluka kwa PSA kumatha kuwonjezera mwayi wopeza khansa ya prostate ikadali koyambirira kwambiri. Koma pali mkangano pazakufunika kwa mayeso a PSA pakuzindikira khansa ya prostate. Palibe yankho limodzi loyenerera amuna onse.

Kwa amuna ena azaka 55 mpaka 69, kuyezetsa magazi kumathandizira kuchepetsa mwayi wakufa ndi khansa ya prostate. Komabe, kwa amuna ambiri, kuwunika ndi chithandizo chitha kukhala chowopsa m'malo mopindulitsa.

Musanayesedwe, lankhulani ndi omwe amakupatsani mwayi wopeza mayeso a PSA. Funsani za:

• Kaya kuwunika kumachepetsa mwayi wanu wakufa ndi khansa ya prostate
• Kaya pali vuto lililonse kuchokera pakuwunika khansa ya Prostate, monga zoyipa zoyesedwa kapena kuchuluka kwa khansa zikapezeka

Amuna ochepera zaka 55 ali ndi mwayi waukulu wokhala ndi khansa ya prostate ndipo ayenera kuyankhulana ndi omwe amawapatsa za PSA ngati:

• Khalani ndi mbiri yapa khansa ya prostate (makamaka mchimwene kapena bambo)
• Ndi African American

Zotsatira za PSA sizingapeze khansa ya prostate. Ndi prostate biopsy yokha yomwe imatha kudziwa khansara.

Wothandizira anu ayang'ana zotsatira zanu za PSA ndikuganizira zaka zanu, mtundu wanu, mankhwala omwe mukumwa, ndi zinthu zina kuti muwone ngati PSA yanu ndiyabwino komanso ngati mukufuna mayeso ena.

Mulingo wabwinobwino wa PSA umawerengedwa kuti ndi ma nanogramu 4.0 pa mililita (ng / mL) yamagazi, koma izi zimasiyanasiyana ndi zaka:

• Kwa amuna azaka za 50 kapena kupitilira apo, mulingo wa PSA uyenera kukhala wochepera 2.5 nthawi zambiri.
• Amuna achikulire nthawi zambiri amakhala ndi ma PSA okwera pang'ono kuposa anyamata.

Mulingo wapamwamba wa PSA walumikizidwa ndi mwayi wochulukirapo wokhala ndi khansa ya prostate.

Kuyesedwa kwa PSA ndi chida chofunikira chodziwira khansa ya prostate, koma sikuti ndi yopanda tanthauzo. Zina zimatha kuyambitsa PSA, kuphatikiza:

• Prostate wokulirapo
• Matenda a Prostate (prostatitis)
• Matenda a mkodzo
• Kuyesedwa kwaposachedwa pa chikhodzodzo (cystoscopy) kapena prostate (biopsy)
• Catheter chubu posachedwa yayikidwa mu chikhodzodzo kuti mukhe mkodzo
• Kugonana kwaposachedwa kapena kutulutsa umuna
• Colososcopy yaposachedwa

Wopezayo amakambirana zinthu zotsatirazi posankha gawo lotsatira:

• Zaka zanu
• Mukadakhala ndi mayeso a PSA m'mbuyomu komanso kuchuluka kwake komanso kuthamanga kwanu kwa PSA kwasintha
• Ngati chotupa cha prostate chidapezeka mukamayesedwa
• Zizindikiro zina zomwe mungakhale nazo
• Zina mwaziwopsezo za khansa ya prostate, monga mafuko komanso mbiri ya banja

Amuna omwe ali pachiwopsezo chachikulu angafunike kuyesedwa kambiri. Izi zingaphatikizepo:

• Kubwereza mayeso anu a PSA, nthawi zambiri mkati mwa miyezi itatu. Mutha kulandira chithandizo cha matenda a prostate poyamba.
• Prostate biopsy idzachitika ngati gawo loyamba la PSA ndilokwera, kapena ngati mulingo uzikukwera pomwe PSA imayesedwa kachiwiri.
• Chiyeso chotsatira chotchedwa PSA yaulere (fPSA). Izi zimayeza kuchuluka kwa PSA m'magazi anu omwe samangidwa ndi mapuloteni ena. Kutsika kwa mayeso awa, ndizotheka kuti khansa ya prostate ilipo.

Mayesero ena amathanso kuchitidwa. Udindo weniweni wa mayeserowa posankha chithandizo sichikudziwika.

• Kuyezetsa mkodzo kotchedwa PCA-3.
• MRI ya Prostate itha kuthandiza kuzindikira khansa m'dera la prostate komwe kumakhala kovuta kufikira nthawi yolemba.

Ngati mwalandira chithandizo cha khansa ya prostate, kuchuluka kwa PSA kumatha kuwonetsa ngati mankhwala akugwira ntchito kapena ngati khansayo yabwerera. Kawirikawiri, msinkhu wa PSA umakwera pasanakhale zizindikiro zilizonse. Izi zitha kuchitika miyezi kapena zaka zisanachitike.

Pali chiopsezo chochepa chotenga magazi anu. Mitsempha ndi mitsempha imasiyana mosiyanasiyana kuchokera pa munthu wina kupita kwina, komanso kuchokera mbali imodzi ya thupi kupita mbali inayo. Kutenga magazi kuchokera kwa anthu ena kumatha kukhala kovuta kuposa ena. Zowopsa zina zomwe zimakoka magazi ndi zochepa, koma mwina ndi izi:

• Kutaya magazi kwambiri
• Ma punctures angapo kuti mupeze mitsempha
• Kukomoka kapena kumva mopepuka
• Hematoma (magazi akuchuluka pansi pa khungu)
• Kutenga (chiopsezo chochepa nthawi iliyonse khungu likasweka)
