I-nevus ibizwa ngokuba yi-mole.
I-nevus yi-tumor (noncancerous) i-tumano-tumor tumor, ebizwa ngokuba yi-mole. I-Nevi (ubuninzi be-nevus) ayidla ngokuzalwa kodwa iqala ukuvela kubantwana nakwishumi elivisayo. Uninzi lwama-moles aluyi kubangela nayiphi na ingxaki, kodwa umntu onama-50 okanye ngaphezulu i-moles iyakwazi ukuvelisa i- melanoma , uhlobo olushushu kakhulu lomhlaza wesikhumba .
Yintoni iCatal Cancer?
Umhlaza wesikhumba - ukukhula okungavamile kweeseli zelusu - ngokuqhelekileyo kuvela kwesikhumba evezwe elangeni.
Kodwa olu hlobo lwesifo somhlaza lungenzeka nakwiindawo zesikhumba sakho esingaqhelekanga ekukhanyeni kwelanga. Kukho iintlobo ezinkulu ezintathu zengqondo yomhlaza - basal cell carcinoma, squamous cell carcinoma kunye ne-melanoma. Ukufumanisa kwangaphambili umdlavuza wesikhumba kukunika ithuba elihle lokufumana unyango lomhlaza wesikhumba.
Iingxaki zeCatcer Cancer
I-melanoma iyenzeka xa kukho into ehamba phambili kwiiseli ezinokuvelisa i-melanin (i- melanocytes ) enika umbala kwesikhumba sakho.
Ngokuqhelekileyo, iiseli zesikhumba zikhula ngendlela elawulwayo kunye neyolawulo - iiseli ezintsha ezinempilo zitshintshe iiseli ezinde kwiphepha lakho, apho zifa kwaye ekugqibeleni ziwa. Kodwa xa ezinye iiseli zivelisa umonakalo we-DNA, iiseli ezintsha zingaqala ukukhula kolawulo kwaye ekugqibeleni ziyakwenza inqwaba yeeseli zomhlaza.
Yiloo nto eyonakalisa i-DNA kwiiseli zesikhumba kunye nendlela oku kuholela ngayo kwi-melanoma ayicaci. Kusenokwenzeka ukuba udibaniso lwezinto, kubandakanya ukusingqongileyo kunye nemfuza, kubangela i-melanoma.
Sekunjalo, oogqirha bakholelwa ukuba ukukhanya kwe-UV ultraviolet (UV) ukusuka elangeni kunye nokukhanyisa izibani kunye nemibhede kukubangela phambili ye-melanoma.
Ukukhanya kwe-UV akubangeli zonke i-melanomas, ngakumbi ezo zenzeka kwiindawo ezisemzimbeni wakho ezingafumani ukukhanya kwelanga. Oku kubonisa ukuba ezinye izinto zingabangela umngcipheko we-melanoma.
UkuCoca kweCanscer Screening
Wena kunye nogqirha wakho unokuqwalasela iinketho zokujonga izinto ezifana ne:
- Iimviwo zesikhumba ngumqeqeshi oqeqeshiwe. Ngethuba lokuphonononga kwesikhumba, ugqirha wakho uhlolisisa ikhanda lakho.
- Iimvavanyo zesikhumba ozenzayo ekhaya. Ukuzivocavoca kunokukunceda ufunde i-moles, i-freckles kunye nezinye izikhumba eziqhelekileyo kuwe ukuze uqaphele nayiphi na utshintsho. Kulungele ukwenza oku kumi phambi kwesibuko esipheleleyo ngexesha usebenzisa isibuko sandla ukuhlola indawo enzima ukubona. Qinisekisa ukuba uhlolisise imida, iminyango, kunye namacala emilenze yakho nemilenze. Ukongezelela, khangela i-groin yakho, isikhumba, izikhonkwane, iingqatha zeenyawo zakho kunye nezikhala eziphakathi kwezwane zakho.
Ezinye iinkampani zonyango zicebisa iimviwo zesikhumba ngogqirha wakho kunye nawe. Abanye abacebisi ukuhlolwa kweengxaki zomhlaza ngenxa yesikhalazo ngenxa yokuba akucaci ukuba ukuhlola kukugcina ubomi. Endaweni yoko, ukufumana imvukuzane engavumelekanga kunokukhokelela kwi-biopsy, leyo leyo, ukuba i-mole ifunyanwe ingabi nomhlaza, ingakhokelela ekubandezelweni okungadingekile, ukuxhalaba kunye neendleko. Thetha ugqirha wakho malunga nokuba ukuhlola kukulungele ntoni kusekelwe kwingozi yomhlaza wesikhumba.
Iintlobo ze-Nevi
Kukho iintlobo ezininzi ze-nevi. I-dysplastic (okanye "i-atypical") i-nevus yinto enkulu, engafaniyo ngokungavumelekanga eyenza kakhulu ingozi yomntu we -melanoma : Iingxaki ezingama-50 zeengxaki ze-melanoma zenzeka kubantu abane-dysplastic nevi.
Abantu abanalo mqathango kufuneka babe nokuhlolwa kancinci kancinci nge- dermatologist nganye ezintandathu.
Iimoles zivame ukubonakala ngokukhawuleza ebuntwaneni, kodwa ezinye zikhona ekuzalweni kwabo baneimeko ezibizwa ngokuthi "congenital melanocytic nevi." Umngcipheko wobomi wokufumana i-melanoma kubantu abane-nevi melanocytic nevi iqikelelwe ukuba ibe ngama-10 ekhulwini, kuxhomekeke kubukhulu beavus.
