Abantu abawerako mu maka gange bafunye kookolo... kale nange nja kumufuna? Okutya kuno, ekibuuzo kino kintu ekiri ku birowoozo bya bangi ku ffe. Tuwulidde nti ebika bya kookolo ebimu biyisibwa okuva ku mulembe okudda ku mulala, kwe kugamba, biva mu buzaale, nedda? Well, leero tugenda kwogera ku nkola ey’enjawulo eyinza okukuyamba okuzuula oba olina akabi ka kookolo ow’obuzaale.
Okukebera kuno okw’obuzaale kye ki?
Mu ngeri ennyangu, kino kigezo ekitunuulira DNA mu mubiri gwaffe. Lowooza ku mubiri gwaffe ng’ekitabo ekinene eky’okuyigiriza. Ekitabo kino kibuulira buli katoffaali mu mubiri gwaffe engeri gye kalina okukolamu, engeri gye kalina okwawukana, ne ddi lwe kalina okufa. Ebiragiro bino bye tuyita obuzaale .
Oluusi, wayinza okubaawo ensobi mu kuwandiika oba ensobi endala mu kitabo kino. Mu ngeri y’obusawo, enkyukakyuka zino mu buzaale tuziyita . Kookolo abaawo ng’obutoffaali obwa bulijjo butandika okwawukana mu ngeri etafugibwa olw’enkyukakyuka ey’ekika kino ey’obuzaale.
Ebiseera ebisinga, enkyukakyuka zino ez’obuzaale ezireeta kookolo tezisikira. Wabula wakati wa 5% ne 10% ku kookolo yenna ava ku nkyukakyuka mu buzaale ze tusikira okuva mu bazadde baffe. Okukebera obuzaale kuzingiramu okukwata omusaayi oba amalusu go n’onoonya enkyukakyuka mu buzaale mu mubiri gwo.
Naye kino kikuume mu birowoozo. Ne bwe kiba nti okukebera kuno kuzudde nti olina enkyukakyuka mu buzaale eyongera ku bulabe bw’okufuna kookolo, tekitegeeza nti ddala ojja kufuna kookolo. Kitegeeza kyokka nti ‘akabi’ kwo ak’okukwatibwa kookolo kali waggulu katono okusinga abantu abalala.
Omukugu mu kubuulirira ku buzaale asobola okukunnyonnyola engeri entuufu ebivaamu bino gye biyinza okukosaamu obulamu bwo.
Bika ki ebya kookolo ebiyinza okusikira?
Waliwo ebika bya kookolo ebiwerako ebiyinza okuva ku nkyukakyuka mu buzaale ezisikira. Ebikulu bye bino:
- Kookolo w’amabeere
- Kookolo w’olubuto olunene
- Kookolo w’ekibumba
- Kookolo w’enkwaso
- Kookolo w’olubuto
- Kookolo w’enseke
- Kookolo w’olubuto
- Kookolo w’ekibumba
- Kookolo wa nnabaana
Ebigezo bino eby’obuzaale tebikebera kookolo. Mu kifo ky’ekyo, bakebera enkyukakyuka ez’enjawulo mu buzaale eziyinza okuleeta kookolo. N’okutuusa kati bannassaayansi bazudde obuzaale obusoba mu 400 obukwatagana ne kookolo ow’obuzaale. Bino bisobola okwawulwamu ebibinja ebikulu bisatu.
| Ekika ky’ensengekera y’obutonde (Genotype). | Mu ngeri ennyangu, by’okola | Kiki ekibaawo nga kikyusiddwa? |
|---|---|---|
| Ensengekera z’obuzaale eziziyiza ebizimba Okugeza: BRCA, obuzaale bwa P53 | Zino ziringa ‘buleeki’ z’emmotoka. Omulimu gwabwe kwe kuyimiriza okukula kw’obutoffaali bwa kookolo. | Ng’emmotoka bw’etesobola kuyimirira nga buleeki zikomye okukola, obuzaale buno bwe bukyusiddwa, obutoffaali bwa kookolo bukula nga tebufugibwa. |
| Ebirungo ebiyitibwa proto-oncogenes | Bino bifaanana ‘accelerator’ mu mmotoka. Ziyamba obutoffaali okukula ku sipiidi eya bulijjo, nga bwe kyetaagisa. | Nga accelerator bw’ezibikira, sipiidi y’emmotoka tesobola kufugibwa, bino bwe bikyusibwakyusibwa, okukula kw’obutoffaali bwa kookolo kwanguyira. |
| Ensengekera z’obuzaale eziddaabiriza DNA | Bino bifaanana nga ‘galagi’ mwe bazimbira mmotoka. Ziddaabiriza ensobi n’okwonooneka okubaawo mu DNA yaffe. | Ng’emmotoka bw’etesobola kuddabirizibwa nga galagi eggaddwa, obuzaale buno bwe bukyusiddwa, ensobi za DNA teziyinza kuddaabirizibwa, ne ziggulawo ekkubo kookolo w’ayinza okubaawo. |
Ani ayagala okukola ekigezo eky’ekika kino?
Singa omusawo wo alowooza nti oyinza okuba n’obulabe obw’obuzaale obwa kookolo okusinziira ku byafaayo byo eby’obujjanjabi oba ebyafaayo by’obujjanjabi bw’amaka go, ayinza okukuwa amagezi okukeberebwa kuno.
Okusinziira ku byafaayo byo eby’obujjanjabi:
- Bwoba obadde n'ebika bya kookolo eby'enjawulo ebiwerako .
- Singa walina kookolo ku myaka emito ennyo .
- Singa omuntu ow'emyaka gyo oba ekikula kyo aba azuuliddwa n'ekika kya kookolo ekitali kya bulijjo .
- Mu bitundu byombi ebibiri , ng’ensigo bbiri n’amabeere abiriBw’oba olina kookolo.
- Bw’oba olina obubonero obulala obukwatagana n’obulwadde bwa kookolo obumu obw’obuzaale (okugeza, omuntu alina obulwadde bwa Neurofibromatosis Type 1 naye ayinza okufuna ebizimba ebitali bya kookolo).
Okusinziira ku byafaayo by’obujjanjabi bw’amaka go:
- Singa abantu abawerako mu maka go babadde n'ekika kya kookolo kye kimu .
- Singa ab'omu maka abawerako baba bafunye kookolo ku myaka emito .
- Singa ab’enganda abawerako ku ludda lumu olw’amaka baba bafunye ekika kya kookolo kye kimu (e.g., ku ludda lwa maama).
- Singa omuntu mu maka go yazuulibwa dda ng’alina enkyukakyuka mu buzaale ekyongera obulabe bw’okufuna kookolo.
"Ow'oluganda olw'oku lusegere" kiyinza okukutabula katono, si bwe kiri? Abasawo batera okusinga okutwala ab’eŋŋanda zo eza ddaala erisooka . Ekyo kitegeeza maama wo, taata wo, baganda bo, n’abaana bo . Naye mu mbeera ezimu, ebyafaayo by’obujjanjabi bw’abooluganda ab’ewala ennyo nabyo biyinza okuba ebikulu.
Bw’oba tokakasa oba weetaaga okukeberebwa kuno oba nedda, kirungi okwogera n’omusawo wo oba omukugu mu kubuulirira ku buzaale ku nsonga eno .
Okugezesebwa kuno kukolebwa kutya?
Omutendera ogusooka era ogusinga obukulu nga tonnaba kukeberebwa kuno kwe kubuulirira ku buzaale . Omubuulirizi omutendeke mu ngeri ey’enjawulo ajja kukunnyonnyola buli kimu.
- Ddala ekigezo kino kikugwanidde?
- Kiki ekigezo ekisinga okukusaanira okukola?
- Birungi ki n’ebibi ebiri mu kugezesebwa kuno?
- Ebivaamu bisobola okukosa obulamu bwo n’obulamu bwo.
- Ebivaamu bino bikwata bitya ku maka go?
Oluvannyuma lw’okukubaganya ebirowoozo ku bino byonna, okugezesebwa kukolebwa okusinziira ku by’oyagala. Ebiseera ebisinga, omusaayi oba amalusu bakuggyibwako ne basindikibwa mu laboratory. Eyo, abakugu bakebera obuzaale bwo oba tewali nkyukakyuka. Ebivuddemu bwe bimala okuyingira, lipoota esindikibwa eri omusawo wo.
Oyinza okuba nga walabye ebikozesebwa mu kukebera awaka. Naye ebivaamu bye bawa tebitera kuba bijjuvu oba bituufu. Ate era, bwe kikolebwa ng’oyita mu musawo , ebyama by’ebikwata ku by’obujjanjabi byo bikuumibwa mu mateeka . N'olwekyo bulijjo kiba kya bulabe era kirungi kino okukikola nga weebuuzizza ku musawo oba omubuulirizi ku buzaale .
Ebiseera ebisinga kitwala wiiki nga bbiri oba ssatu okufuna ebivaamu.
Otegeera otya eby’okuddamu mu lipoota y’ekigezo?
Ebivuddemu bisobola okwawulwamu ebika bisatu ebikulu.
| Alizaati | Kino kitegeeza ki? |
|---|---|
| Lungi | Ozuuliddwa nti olina enkyukakyuka mu buzaale ekyongera obulabe bw’okufuna kookolo. Ekyo tekitegeeza nti ddala ojja kukwatibwa kookolo, naye akabi kali waggulu . |
| Ekibi | Ensengekera z’obuzaale ezaakeberebwa tezaazudde nkyukakyuka eyongera ku bulabe bwa kookolo. Bw'oba omanyi nti omuntu mu maka go alina enkyukakyuka eno, naye nga togirina, eyitibwa "true negative." |
| Enkyukakyuka y’amakulu agatali makakafu (VUS) . | Enkyukakyuka (mutation) ezuuliddwa mu buzaale bwo, naye bannassaayansi tebannaba kukakasa oba eyongera ku bulabe bw’okufuna kookolo. Kiyinza okuba enkyukakyuka eya bulijjo, etali ya bulabe, oba eyinza okuzuulibwa nti ekwatagana ne kookolo mu biseera eby’omu maaso. |
Kiki ky’okola ng’omaze okufuna ebyavaamu?
Ka kibeere ki ekivaamu, omukugu mu kubudaabuda obuzaale ajja kwogera naawe ku nsonga eyo mu bujjuvu. Singa ebyavaamu biba birungi , ojja kwogera ku:
- Enkyukakyuka mu nteekateeka yo ey’ebyobulamu: Ekubaganya ebirowoozo ku kukebera okw’enjawulo okuzuula kookolo amangu, gamba ng’okukebera amabeere oba okukebera ekibumba buli kiseera, n’ebintu by’oyinza okukola okukendeeza ku bulabe bwo obwa kookolo.
- Enteekateeka y’amaka: Enkyukakyuka eno mu buzaale eyogerwako mu ngeri y’emikisa gy’okugiyisa mu mwana wo.
- Okutegeeza ab’omu maka: Kino kijja kwogera ku ngeri ekinaavaamu gye kinaakwata ku b’eŋŋanda zo ez’omusaayi (abazadde, baganda bo, abaana) n’emitendera gye balina okuyitamu.
Ne bwe kiba nti ebyavaamu biba negativu oba VUS , oyinza okwetaaga okulaba omusawo wo emirundi mingi oba okukeberebwa ebirala. Singa amawulire amapya aga ssaayansi gafuna ebikwata ku bivudde mu VUS, omusawo wo ajja kukutegeeza.
Birungi ki n’okusoomoozebwa okuli mu kugezesebwa kuno?
Okufaananako n’okukeberebwa kwonna okw’abasawo, kuno kulina emigaso gyakyo nga kw’otadde n’okusoomoozebwa okumu.
| Emigaso | Ebizibu / Okusoomoozebwa |
|---|---|
| Okutya n’obutali bukakafu mu mutima gwange bibula era mpulira obuweerero. | Okutya, okweraliikirira, n’okunyigirizibwa okuteetaagisa ku biyinza okuvaamu. |
| Osobola okukola emitendera okukendeeza ku bulabe bwa kookolo n’okumuzuula nga bukyali. | Okubuulira ab’omu maka ku nsonga eno kiyinza okukosa omukwano. |
| Omusawo wo ajja kukuyamba okukola enteekateeka y’ebyobulamu ekukwatako. | Okwesalira omusango kuyinza okuva ku kintu ekisikira. |
| Ab’omu maka go nabo bafuna omukisa okumanya akabi akali mu bulamu bwabwe. | Okugezesebwa kuno kumalawo ssente ezimu. |
Omubuulirizi w‟obuzaale asobola okukuyamba okukola ku nneewulira zino ez‟enneewulira n‟okukulambika ku ngeri y‟okwogera n‟ab‟omu maka go ku nsonga eno, y‟ensonga lwaki kikulu nnyo okuba n‟obuwagizi bwabwe mu nkola eno yonna.
Obubaka Obutwala Awaka
- Okukebera obuzaale ku kookolo tekikugamba nti olina kookolo, wabula ku bulabe bwo obw’obuzaale obw’okukwatibwa kookolo.
- Kikulu nnyo okwogera n’omubuulirizi w’obuzaale nga tonnafuna bivudde mu kukeberebwa kuno n’oluvannyuma lw’okufuna.
- Ne bwe kiba nti ebyavaamu biba birungi, tosattira era kola ekyetaagisa okukendeeza ku bulabe bwo n’okuzuula kookolo nga bukyali, ng’omusawo bw’akugamba.
- Okwogera mu lwatu era mu bwesimbu n’omusawo wo ku byafaayo bya kookolo w’amaka go kye kimu ku bintu ebisinga obulungi by’oyinza okukola okukuuma obulamu bwo.
