Umzimba wethu ufana nomzi-mveliso ontsonkothileyo nomangalisayo. Kukho iqela lezithunywa ezitshintshiselana ngolwazi phakathi kwamacandelo ahlukeneyo alo mzi-mveliso kwaye zisebenza ngokubambisana. Ngamafutshane, ezi zithunywa zezo zinto sizibiza ngokuba zii-hormone . Umzimba wethu awunakusebenza ngaphandle kwee-hormone. Nangona kunjalo, ngamanye amaxesha ezi hormone zondla ezinye iiseli zomhlaza, zinceda ukuba zikhule kwaye zisasazeke. Kulapho unyango lwee-hormone luba lubalulekile kuthi.
Ngoko ke yintoni le nyango yehomoni?
Ngamafutshane, unyango lweehomoni luyayithintela iiseli zomhlaza ekufumaneni iihomoni ezifunekayo ukuze zikhule. Xa iiseli zomhlaza zingenazo ezi homoni, ziyalahlekelwa ngamandla azo okukhula, ukwahlukana, nokusasazeka.
Ngamanye amaxesha oogqirha basebenzisa olu nyango bodwa. Balusebenzisa kunye nezinye iindlela zonyango, ezifana notyando, i-chemotherapy, okanye unyango lwe-radiation. Ngamanye amaxesha, emva kokuba zonke iindlela zonyango eziphambili zigqityiwe, unyango lwe-hormone lunikwa ukunciphisa umngcipheko wokubuya komhlaza.
Lusebenza njani olu nyango?
Kukho iindlela ezintathu eziphambili olu nyango olusebenza ngazo:
1. Ukuthintela ukuveliswa kweehomoni: Kunikwa amayeza okuthintela imizimba yethu ekuveliseni iihomoni ezifunwa ziiseli zomhlaza. Kwezinye iimeko, amadlala avelisa ezo homoni (umzekelo, amasende kumadoda) nawo anokususwa ngotyando.
2. Ukuthintela ukusebenza kweehomoni: Oku kuquka ukuvala indlela yokuba iihomoni zifikelele kwaye zinamathele kwiiseli zomhlaza. Xa iihomoni zingakwazi ukufikelela kwaye zinamathele kwiseli, iseli ayifumani myalezo wokukhula.
3. Ukutshintshwa kweehomoni ezidityanisiweyo: Ngamanye amaxesha, iihomoni ezifanayo eziphilayo ezenziwe kwilebhu zinikwa umzimba. Nangona ezi homoni zidityanisiweyo zifana neehomoni zendalo, iiseli zomhlaza azikwazi ukuzisebenzisa ukukhula. Ngoko ke xa ezi zithatha indawo yeehomoni zendalo, ukukhula kweeseli zomhlaza kuyayeka.
Zeziphi iintlobo zomhlaza ezisetyenziselwa unyango lwehomoni?
Ayizizo zonke iintlobo zomhlaza ezinyangwa ngeehomoni. Olu nyango lusetyenziswa kakhulu kwiintlobo zomhlaza ezixhomekeke kwiihomoni, nto leyo ethetha ukuba zidinga iihomoni ukuze zikhule.
| Uhlobo lomhlaza | Inkcazo |
|---|---|
| Umhlaza weprostate | Isetyenziselwa ukulawula ukukhula kweeseli zomhlaza ezixhomekeke kwiihomoni zamadoda (androgens). |
| Umhlaza webele | Isetyenziselwa ukulawula iiseli zomhlaza ezibuthathaka kwi-estrogen (ER-positive). |
| Umhlaza we-Ovarian | Isetyenziselwa ezinye iintlobo ezingaqhelekanga zomhlaza wesibeleko. |
| Umhlaza wesibeleko | Isetyenziselwa ukulawula ukukhula komhlaza xa sele usasazekile okanye uphinda uvela. |
Unyango lweHormonal lomhlaza weprostate
Iiseli zomhlaza weprostate zihlala zivuselelwa ziihomoni zamadoda (androgens) ezifana ne-testosterone. Ngoko ke injongo yonyango kukunciphisa amanqanaba ezi homoni okanye ukuzithintela ukuba zingasebenzi. Ngamanye amaxesha, ukususwa kwesende elinye okanye omabini (orchiectomy) kwenziwa ngotyando.
Amayeza asetyenziswa kakhulu:
- I-Abiraterone acetate: Eli yeza lithintela ukuveliswa kweehomoni zamadoda kwiiseli zomhlaza weprostate.
- Ii-agonists ze-LHRH: La mayeza abonisa ukuba i-pituitary gland esebuchotsheni bethu iyeke ukuvelisa enye i-hormone (i-luteinizing hormone) enceda ekuveliseni i-testosterone.
- Ii-Antiandrogens: Ezi zithintela ngokuthe ngqo i-hormone testosterone ekubopheni kwiiseli zomhlaza.
Kubalulekile: Iziphumo ebezingalindelekanga zolu nyango ziyahluka kumntu nomntu. Xoxa ngale nto ngokukhululekileyo nogqirha wakho.
Iziphumo ebezingalindelekanga eziqhele ukubonwa:
- Ukutyeba kwakho.
- Ukuncipha okanye ukuphelelwa ngumnqweno wesondo.
- Ukungasebenzi kakuhle kwe-erectile.
- Ukuncipha koxinano lwamathambo (i-Osteoporosis).
Unyango lwehomoni yomhlaza webele
Malunga nama-80% omhlaza wamabele uvakalelwa zii-hormone. Oku kuthetha ukuba iiseli zomhlaza ziyasabela kwi-hormone ye-estrogen yabasetyhini. Ezi zibizwa ngokuba zii-ER-positive cancers . Ngoko ke injongo yonyango kukunciphisa inqanaba le-estrogen emzimbeni okanye ukuthintela i-estrogen ekubopheni kwiiseli zomhlaza.
Olu nyango ludla ngokwenziwa emva kotyando ukunciphisa umngcipheko wokubuya komhlaza. Nangona kunjalo, lukwasetyenziswa ngaphambi kotyando ukunciphisa ithumba okanye ukunyanga umhlaza osele usasazeke kwamanye amalungu omzimba.
| Uhlobo lweziyobisi | Ukusebenza kakuhle |
|---|---|
| Izithinteli zeAromatase | Ithintela i-enzyme (i-Aromatase) evelisa i-estrogen emzimbeni, inciphisa amanqanaba e-estrogen (adla ngokunikwa abafazi emva kokuya exesheni). |
| IiModulators zeSelective Estrogen Receptor (iiSERM) | Ihomoni i-estrogen ithintela iiseli zomhlaza wamabele ukuba zinganamatheli kuyo. |
| Ii-Downregulators ze-Estrogen Receptor (ii-ERD) | Ezi zithintela ii-receptor ze-estrogen kwaye zinciphisa inani lazo. |
Iziphumo ebezingalindelekanga eziqhele ukubonwa:
- Umzimba, iintlungu okanye ukuqina kwamalungu.
- Ndidiniwe.
- Isicaphucaphu nokuhlanza.
- Ukutyeba kwakho.
- Ukuncipha komnqweno wesondo.
- Ukuziva ubushushu obugqithisileyo emzimbeni (ubushushu obugqithisileyo).
- Intlungu yebele okanye ukudumba.
Lunikwa njani olu nyango? Zithini iingenelo kunye neengozi?
Unyango lweehomoni ludla ngokunikezelwa njengepilisi oyithatha yonke imihla. Amanye amayeza ayafumaneka njengeenaliti ozithathayo ngamaxesha athile. Oku kumiselwa ngugqirha wakho.
Eyona nzuzo iphambili kukuba, xa idityaniswe nezinye iindlela zonyango, inokucothisa okanye iyeke ngokupheleleyo ukukhula kweeseli zomhlaza.
UmngciphekoEzi ziziphumo ebezingalindelekanga. Kodwa khumbula, ayinguye wonke umntu ozifumana zonke. Kukwakho neendlela zokulawula ezi ziphumo ebezingalindelekanga. Kubalulekile ukuxelela ugqirha wakho ngayo nayiphi na ingxaki oyifumanayo. Iziphumo ebezingalindelekanga zinokwahluka ngokuxhomekeke kwimeko yakho yempilo kunye nonyango olufumanayo.
Umyalezo Wokuya Ekhaya
