Ukubaluleka kokujongwa komhlaza wekoloni kukufumanisa kunye nokunyanga umhlaza wekoloni kwangethuba, ngaloo ndlela kuphuculwe impumelelo yonyango kunye namazinga okuphila. Umhlaza wekholoni wenqanaba lakwangoko uhlala ungenazo iimpawu zicacileyo, ngoko ke uvavanyo lunokunceda ekuchongeni iimeko ezinokwenzeka ukuze unyango lusebenze ngakumbi. Ngokuhlolwa rhoqo umhlaza wekolon, izinto ezingaqhelekanga zinokubonwa kwangethuba, nto leyo evumela ukuxilongwa nonyango olongezelelweyo, ngaloo ndlela kuncitshiswe umngcipheko wokuba imeko ibe mandundu. Ke ngoko, ukujongwa komhlaza wekolon kuneempembelelo ezibalulekileyo kubo bobabini kunye nempilo yoluntu.

Ukujongwa komhlaza wamathumbu kubalulekile ekubhaqweni kwangethuba kunye nonyango lomhlaza wekholoni.I-CAL (uvavanyo lweCalportectin), I-FOB (Uvavanyo lwegazi lwe-Fecal Occult) kwaye TF (uVavanyo lweTransferrin)ziqhele ukusetyenziswa kwiindlela zokuhlola umhlaza wekoloni.

I-CAL (uvavanyo lweCalprotectin) yindlela yokujonga ngokuthe ngqo ngaphakathi kwikholoni, ekwazi ukufumanisa umdlavuza wekoloni okanye i-polyps yokuqala kwaye ivumele i-biopsy okanye isuswe. Ngoko ke, i-CAL yindlela ebaluleke kakhulu yokuhlola umhlaza wekoloni.

I-FOB (i-fecal occult blood test) yindlela elula yokuhlola efumanisa igazi lobugqi kwi-stool kwaye inokunceda ekuboneni ukopha okubangelwa ngumhlaza wekoloni okanye i-polyps. Nangona i-FOB ingenako ukuxilonga ngokuthe ngqo umhlaza wekolon, inokusetyenziswa njengendlela yokuqala yokuhlola ukunceda ukufumanisa iimeko ezinomhlaza wekholoni.

I-TF (uvavanyo lwe-Transferrin) luvavanyo lwegazi olufumanisa iiprotheni ezithile egazini kwaye lunceda ukuvavanya umngcipheko we-colon cancer. Nangona i-TF ingenakusetyenziswa iyodwa ukukhusela umhlaza wekoloni, inokubonelela ngolwazi olongezelelweyo xa idibene nezinye iindlela zokuhlola.

Isishwankathelo, i-CAL, i-FOB kunye ne-TF zonke zibalulekile ekuhlolweni komhlaza wekoloni. Banokuncedisana ukunceda ukubona umhlaza wekoloni kwangoko kwaye baphucule impumelelo yonyango kunye namazinga okusinda. Ke ngoko, kucetyiswa ukuba abantu abakufaneleyo ukuvavanywa bavavanywe rhoqo umhlaza wekoloni.

Thina iBaysen zonyango sineCal +FOB +TF yekiti yovavanyo olukhawulezayo lunokunceda ekuhlolweni kwangoko kweCaner enemibala.
