Olu vavanyo luyakwazi ukubona i-cancer ekhula ngokukhawuleza
Uvavanyo lwe- Prostate Specific Antigen , olubizwa ngokuba yi-PSA velocity, lusetyenziswe kakhulu kwihlabathi ukufumana nokubeka umlenze womhlaza wesifo somhlaza.
Kwiminyaka emininzi, oogqirha baye basebenzisa ixabiso elipheleleyo le-PSA ukunquma umngcipheko womntu wesifo somhlaza wesifo somhlaza okanye nokuba umhlaza wakhe ubuyile okanye uphumelele. Kodwa ngo-2016, nangona kunjalo, kuye kwacaca ngakumbi ukuba izinga lokutshintsha kwinqanaba le- PSA , okanye i-PSA velocity, linokubaluleka nje njengenombolo eluhlaza ngokwayo.
Indima entsha yePSA Velocity
Iingcaphephe ezininzi zeengcambu zeprotate ngoku ziqwalasela ingqalelo kwizinga lePSA kuphela kodwa kwakhona nokuba liguquke ngokukhawuleza kangakanani xa zichonga ukuba zifuna ukuvavanya iimvavanyo ezingaphezulu , xa ziqala unyango okanye ukuba zixelele izigulane zabo malunga nokuhlaselwa.
Izifundo ezininzi sele zibonise ukuba i-PSA velocity ephakamileyo (umzekelo, ngokukhawuleza kwexesha eliphindwe kabini le-PSA okanye ukunyuka kwe-0.35 ng / mL okanye ngaphezulu ngonyaka) inokubonisa uphawu lomhlaza okhula ngokukhawuleza kungakhathaliseki ukuba izinga eliphezulu lePSA liphezulu kangakanani.
Ngokomzekelo, indoda iya kwixesha eliqhelekileyo ukuhlola uvavanyo lwe-PSA kwaye ibuyela kwi-2.0 ng / mL. Ngenye indlela unempilweni kwaye ugqirha wakhe akaxhaswanga ngumphumo kuba i-2.0 ayikho "phezulu" kwiimeko ezininzi. Kodwa kunyaka ophelileyo izinga lakhe le-PSA laliyi-1.0 ng / mL kwaye unyaka ngaphambi kokuba kube ngu-0.5 ng / mL.
Ngaba ezi ziphumo kufuneka zikhathaze yena okanye ugqirha?
Ngokusekelwe kububungqina obuphakamileyo, impendulo ingenzeka ukuba "yebo." Kulo mzekelo, izinga le-PSA elingaphantsi kwe-2.0 lingasuswa "njengento evamile." Nangona kunjalo, i-PSA yalomntu iphindwe kabini ngonyaka ngamnye iminyaka emibini, eyenza inani elibalulekileyo nokuba liwela ngaphakathi kwinqanaba "eliqhelekileyo".
Le ngongoma ephakamileyo yenguqu yePSA (njenge- PSA velocity ephezulu ) kwaye mhlawumbi ibonisa umhlaza okhula ngokukhawuleza.
Ngamafutshane, ugqirha kule meko kufuneka athathe inyathelo elikhawulezileyo ukufumana eli gulane unyango unyango.
Ukuqhawula phezulu
Ngoko ke, kubalulekile ukuba ulandele amanqanaba akho e-PSA ngaphezu kweminyaka kwaye uqaphele ugqirha wakho kuyo nayiphi na indlela ebonisa ukuba uyayibona, ingakumbi ukuba utshintshe oogqirha kwaye akaqinisekanga ukuba ogqirha wakho ogqirha uphila njani kwimbali yakho yezonyango.
Oogqirha babona amawaka ezigulane ngonyaka kwaye banokuthi bangawuboni ukuba i-PSA yakho iyanda ngokukhawuleza.
Unganqikazi ukubuza ugqirha wakho malunga neziphumo ze-PSA velocity okanye ukucela ukuvavanya okanye ukuhlalutya. Oku kuhamba kabini ukuba ungoqela elinobungozi obuphezulu, njengabantu base-Afrika baseMelika, okanye unomdla wentsapho ye-prostate yomdlavuza.
Ukuba ugqirha wakho ukhuphaza ngale mgca wokubuza imibuzo okanye ubonakala engakhathazeki malunga neziphumo ze-PSA velocity, nangona zibonakala ziphakama ngokukhawuleza njengoko zenza kulo mzekelo ungentla, cinga ukutshintsha oogqirha. Ubomi bakho bubaluleke gqitha ukuba uthathe umngcipheko wokuba yonke into iyinto evamile, xa amazinga akho e-PSA anokutyhila ngenye indlela. Ukuba ungatshintshi oogqirha, ubuncinane ujonge ukufumana umbono wesibini okanye wesithathu malunga ne-PSA velocity kunye nembali yonyango.
Ukuphikelela kwezigulane kuye kwalondoloza ubomi obungenakubalwa.
