Lokhu kuhlolwa kungakwazi ukubona amacciwane okukhula okusheshayo
Isivivinyo se- Prostate Specific Antigen , esaziwa nangokuthi i-PSA velocity, sisetshenziswe kabanzi emhlabeni wonke ukuthola nokuqapha umdlavuza wesibeletho.
Sekuyiminyaka eminingi odokotela bebelokhu besebenzisa ukubaluleka okuphelele kwe-PSA ukunquma ingozi yomuntu wesifo somdlavuza wesifo sofuba noma ngabe umdlavuza wakhe ubuyele noma uphumelele. Nokho, kusukela ngo-2016, sekuye kwacaca ukuthi izinga lokuguqulwa kwezinga le- PSA , noma i-PSA velocity, lingabaluleka kakhulu njengenombolo eluhlaza ngokwayo.
Intsha entsha yePSA Velocity
Ochwepheshe abaningi bomdlavuza we-prostate manje abakucabangi nje kuphela ngezinga le-PSA kodwa nokuthi bashintsha kanjani ngokushesha uma benquma ukuthi bazokwenza yini ukuhlolwa okuqhubekayo , nini ukuqala ukwelashwa noma ukuthi yini ongayitshela iziguli zabo mayelana nokugxekwa.
Izifundo eziningi manje sezibonise ukuthi i-PSA velocity ephakeme (isibonelo ngokuphindaphindiwe kokuphindaphindiwe kwe-PSA noma ukuphakama kwe-0.35 Ng / mL noma ngaphezulu ngonyaka) ingase ibonise umdlavuza okhula ngokushesha kungakhathaliseki ukuthi izinga eliphezulu le- PSA liphakeme kangakanani.
Isibonelo, indoda iya ukuhlola ukuhlolwa kwe-PSA futhi ibuyela ku-2.0 ng / mL. Ngenye indlela unempilo futhi udokotela wakhe akaxhasi umphumela kusukela ku-2.0 akuyona "izinga eliphezulu" ezimweni eziningi. Kodwa ngonyaka odlule izinga lakhe le-PSA laliyi-1.0 ng / mL nonyaka ngaphambi kokuthi kube ngu-0.5 ng / mL.
Ingabe lemiphumela kufanele ikhathazeke yena noma udokotela wakhe?
Ngokusekelwe ebufakazini obukhulayo, impendulo kungenzeka ukuthi "yebo." Kulesi sibonelo, izinga le-PSA eliphansi kakhulu le-2.0 lingasuswa njenge "evamile." Kodwa-ke, i-PSA yalowo muntu iphindwe kabili ngonyaka ngamunye iminyaka emibili, okwenza inombolo ibaluleke ngisho noma iwela ngaphansi kobubanzi "obuvamile".
Lokhu kuyinani eliphakeme lokushintsha kwe-PSA (njenge- PSA velocity ephakeme ) futhi kungenzeka ukuthi lisho umdlavuza okhula ngokushesha.
Ngamafuphi, udokotela kuleso simo kufanele athathe isinyathelo esisheshayo ukuze lo mgulane uphinde uthole ukwelashwa.
Ukufaka phezulu
Ngakho-ke, kubalulekile ukugcina ithrekhi yamazinga akho e-PSA phakathi neminyaka futhi uqaphele udokotela wakho kunoma yiziphi izitayela ozibonayo, ikakhulukazi uma ushintsha odokotela futhi ungaqiniseki ukuthi wazi kanjani udokotela wakho omusha ngomlando wakho wezokwelapha.
Odokotela babona izinkulungwane zeziguli ngonyaka futhi bangase bangaboni ukuthi i-PSA yakho iye yanda ngokushesha.
Ungangabazi ukubuza udokotela wakho ngemiphumela yakho ye-PSA velocity noma ukucela ukuhlolwa okwengeziwe noma ukuhlaziywa. Lokhu kubuye kabili uma uyingxenye eqenjini elibhekene neengozi, njengamadoda ase-Afrika aseMelika, noma unomlando womndeni wesifo somdlavuza we-prostate.
Uma udokotela wakho ekhishwa ngalolu daba lokubuza noma ebonakala engakhathazeki ngemiphumela yakho ye-PSA velocity, ngisho noma ebonakala ekhuphuka ngokuphawulekayo njengoba enza kulesi sibonelo esingenhla, cabangela ukushintsha odokotela. Ukuphila kwakho kuyigugu kakhulu ukufaka ingozi yokuthi konke okujwayelekile, lapho amazinga akho e-PSA angase aveze ngenye indlela. Uma ungashintshi odokotela, okungenani ucabange ukuthola umbono wesibili noma wesithathu mayelana ne-PSA velocity yakho nomlando wezokwelapha.
Ukuphikelela kweziguli kuye kwalondoloza ukuphila okungenakubalwa.
