Khansara ndi mawu owopsya kwambiri moti ndikumva kuti ndiyenera kukumbukira nkhani zabodza zomwe khansara ya prostate imayambitsa zizindikiro. Choncho ngati khansara ya prostate imatsimikiziridwa kukhalabe zizindikiro, ndikuganiza kuti PSA yayesedwa ndipo ili yonse, n'chifukwa chiyani mawebusaiti amapereka mndandanda wautali wa zizindikiro za khansa ya prostate?
Kodi zinganamizidwe bwanji zowopsya?
Kwenikweni, mawebusayitiwa amawombera nthawi yosawerengeka, kufotokozera mkhalidwe umene unalipo Pambuyo poyesedwa PSA. Zizindikiro zomwe amalembetsa, monga kupweteka kwa mafupa, kusintha kwa kukodza, kutopa, kupweteka kwa m'mimba, kumachitika mwa amuna omwe ali ndi matenda apamwamba.

Ndimatchula testosterone chifukwa mkhalidwe umodzi womwe khansa ya prostate ikhoza kupitilira pamene PSA imakhala yotsika ndi pamene ma teti a testosterone ali otsika. Komabe, kukhala ndi digiri ya testosterone yakuvutitsa, komabe si zachilendo. Ndipo sizingakhale zofunikira kuti muyesedwe magazi kuti mudziwe kuti masiteti a testosterone ndi otsika bwanji. Mlingo wochepa kwambiri wa testosterone umapangitsa ubongo wa munthu kukhala wopanda mphamvu kwa chiwerengero chachikazi. Amaleka kuganizira za kugonana kwathunthu. Kupezeka kwathunthu kwa libido kumangokhalira kumvetsera munthu ndikumupangitsa kuti apeze chithandizo chamankhwala kuti adziwe zomwe zikuchitika.
Kuyambira pomwe PSA ikuyesa kuwonetsa kuthekera kwa kupezeka ndi khansa ya prostate yapamwamba, tiyeni tione njira zoyenera zochitira opaleshoni yoyenera. Chigawo cha PSA kukhala "chachilendo" chimasiyana, koma kawirikawiri PSA pamwamba pa 4.0 mwa amuna oposa 60 ayenera kupitilizidwanso. Amuna achichepere omwe ma PSA ali pamwamba pa 2.5 ayenera kukhala ndi kuyesa.
M'dziko langa, ndikugwira ntchito monga katswiri wa kansa ya prostate, n'zovuta kukhulupirira kuti amuna oposa 40 amalephera kuyesa PSA pachaka. Komabe, zodabwitsa, ziŵerengero zimasonyeza momveka bwino kuti amuna ambiri amalakwitsa kuti asamaone nthawi zonse PSA yawo.
Kuyeza kwa PSA ndi njira yokhayo yodziwira khansara ya prostate kumayambiriro koyambirira (chidziwitso cha mayesero achidziwitso chili ndi phindu, koma osati zambiri).
Mitsuko ndi Mabotolo a PSA Screening
Asanavomereze kuti FDA ikuvomerezedwa ndi kuyesa kwa PSA mu 1987 (kuphatikizapo prostate biopsy chaka chomwechi), khalidwe la kansa ya prostate yoyamba inali yosadziwika. Tsopano, madokotala akuzindikira ndi kuwerengera kansa ya prostate yoyambirira yomwe ikuchitika molondola.
Ntchito zina za PSA kupatula Kuyeza

Amuna oposa 200,000 amapezeka chaka chilichonse chifukwa cha kufufuza kwa PSA . Komabe, palinso ntchito zina. Chitsanzo chimodzi ndi momwe PSA imathandizira kufotokozera sitepe ya khansa patatha kansa ya prostate. Amuna omwe ali ndi khansara PSA pansi pa 10 akugwirizanitsidwa ndi mtundu wambiri wosadziletsa wa kansa ya prostate. Kumbali ina, chiwerengero cha PSA choposa 20 chimayimira mtundu woopsa kwambiri wa kansa ya prostate. PSA imathandizanso kuti ntchito yothetsera khansa ikhale yofunika kwambiri.
Kusiyanitsa Pogwiritsa Ntchito PSA kwa Kuyeza Kansera ya Prostate
Kuzindikira kanthawi kosavuta kwa khansara ya prostate kumapangitsa mwayi wa khansa kufalikira. Nanga mungathe bwanji kutsutsana ndi kuwonedwa kwa PSA? Kodi matenda oyamba a khansa angakhale oipa? Chodabwitsa n'chakuti, zomwe zakhala zikuwonetseratu kuti PSA ndi yowopsya kwambiri, zomwe zimachititsa kuti anthu 100,000 omwe ali ndi khansa zapang'onopang'ono zisamakhale zoopsa kuti azifalikira.
Izi sizikanakhala zovuta ngati dongosolo lachipatala likanakonzedwa kuti lizitsatira mosavuta awa khansa yopanda vuto. Mwamwayi, chifukwa cha tizilombo tating'onoting'ono ta matenda omwe amatchedwa "khansara," madokotala ndi odwala mofanana amadandaula kwambiri ndikufulumizitsa kuchipatala chosafunikira, kuika mavuto oopsya ndi kugonana.
Ndipotu, kugonjetsa khansa ya prostate yopanda vuto kwakhala vuto lalikulu kotero kuti mu 2011, gulu lothandizira boma la US Preventative Services Task Force , linapereka machenjezo olimbikitsa kuti pulogalamu ya PSA iwonongeke. Ogwira ntchitoyi anatsimikiza kuti mtengo woopsya wa amuna ambiri omwe akuvulazidwa ndi chithandizo chosafunikira kupambana phindu la miyoyo yopulumutsidwa ndi kuyambitsana koyambirira. Madokotala ambiri othandizira anthu apamtima atenga malingaliro a bomawa ndipo atsimikiza kuti asiye kuwonetsa PSA chaka chilichonse chifukwa akukhulupirira kuti akuvulaza kwambiri kuposa zabwino.
Multi-Parametric MRI Scans: Chipulumutso cha PSA Screening
M'malo moletsa kuyesa kwa PSA, pali njira yabwino kwambiri yochepetsera kupitirira. Ngakhale PSA yokwezeka ikusonyeza kuti chinachake chiri choipa ndi prostate, sichikusonyeza mwachindunji kuti vuto ndi okhudzana ndi khansa. Zina zomwe zimayambitsa PSA kukwera kuphatikizapo khansara ndizokulitsa prostate chifukwa cha ukalamba, wotchedwa benign prostatic hypertrophy, ndi kutupa kwa prostate, komwe kumatchedwa prostatitis. Zonsezi sizikugwirizana ndi khansa ya prostate.
PSA Kukwera kwa Glands Zambiri Zamtenda
Zilonda zazikulu za prostate zimapanga PSA zambiri kuposa zochepa za prostate. Njira yabwino yoyezera kukula kwa prostate ndi kugwiritsa ntchito sewero. Kupeza gland wochuluka kungakhale nkhani yabwino, kupereka tsatanetsatane yolimbikitsa komanso yolimbikitsa chifukwa chake PSA ili pamwamba. PSA ndi "yachibadwa" pamene kukula kwa prostate mu masentimita masentimita pafupifupi 10 kuposa PSA.
Mwachitsanzo, mwamuna yemwe ali ndi PSA wa atatu ayenera kukhala pafupi ndi 30cc prostate; pamene PSA ndi 5 gland ayenera kukhala pafupi 50cc. PSA ndi yachilendo ngati ndiposa 50 peresenti kuposa momwe ingayang'anire, malinga ndi kukula kwa prostate. Mwachitsanzo, PSA "yopanda malire" kwa munthu yemwe ali ndi 30cc prostate ndi 4.5 kapena pamwamba. PSA yosadziwika kwa 50cc prostate ili pamwamba pa 7.5. Kwa munthu wokhala ndi 100cc gland , PSA ayenera kukhala pamwamba pa 15 kukayikira.
Mpaka posachedwapa, njira yokhayo yothetsera mavuto onsewa ndiyo kuchotsa prostate nthawi 12 ndi singano biopsy kuchotsa minofu yowonongeka pansi pa microscope. Chifukwa cha mantha aakulu a khansa imene ikusowa, madokotala ambiri adalimbikitsa chiopsezo chilichonse panthawi yomwe PSA imakwera kwambiri. Amuna mamiliyoni amamangidwa ku United States chaka chilichonse. Mchitidwe wamanthawu mwina unali wolondola pamene biopsy inali njira yokhayo yopezera khansa.
Ife tsopano tikudziwa, komabe, kuti kuyesa kugwiritsa ntchito kugwiritsira ntchito maginito maginito resonance imaging (MP-MRI) ndi yolondola kwambiri. Kukongola kwa kugwiritsira ntchito kanema ndiko kuti amuna okha omwe ali ndi chidziwitso chodziwika kuti ali ndi MRI ayenera kukhala ndi chidziwitso . Ndipo chofunika kwambiri, chiwerengerochi chingakwaniritsidwe. Chofunika chimodzi kapena ziwiri zokha zimafunika. Sipanganso nsomba kupyola muyezo wonse wa nkhuni ndi timitengo tomwe timakhala tomwe timapanga. Amuna omwe ali ndi zizindikiro zomveka angathe kupeŵa biopsy palimodzi. Kusintha ndondomeko yochokera kumalo osokoneza bongo kupita ku MP-MRI kumathetsa vuto la kuganizira kwambiri amuna omwe ali ndi PSA.
Pulogalamu Yowonetsera PSA Yoperekedwa
Ndizomveka kuyamba kuyendera PSA chaka chilichonse amuna omwe ali ndi zaka zoposa 45. Amuna omwe ali ndi mbiri ya banja la kansa ya prostate kapena amuna omwe ali African-American ayenera kuyamba kuyesedwa pachaka ali ndi zaka 40. Amuna opitirira zaka 75 omwe ali ndi thanzi labwino ayenera kupitiliza kufufuza .
Kotero, ndi chiani choyambira cha PSA chomwe chiyenera kutsogolera kuwonetsa?

Mwamuna wachikulire makamaka makamaka ngati prostate gland yatsimikiziridwa ndi chofufumitsa chala, chachikulu PSA ya 4.0 ndi malo oyenerera kupeza mafano (ngati nthendayi imamveka, kufufuza kwina n'koyenera ngakhale ngakhale PSA ndi yachibadwa). PSA mayeso a magazi apambana kwambiri maloto odabwitsa kwambiri a madokotala amene anazipeza. Monga chida chilichonse champhamvu, komabe kusagwiritsira ntchito molakwika kungayambitse kupweteka kwambiri komanso kuvulazidwa kosafunikira.
Zonse zabodza pa intaneti zimatanthauza kuti kupweteka kulikonse, ululu, kapena vuto lomwe liri pafupi ndi prostate lingayambitsidwe ndi khansa. Mfundo yakuti funso lofunsidwa kawirikawiri yokhudzana ndi kansa ya prostate ndizoonetsa zizindikiro za khansa ya prostate zimasonyeza kuti anthu akutsogoleredwa ndi mitundu yonse ya nkhaŵa zosafunikira.
