Cancer, malignant melanoma : Ib hom mob qog noj ntshav uas pib hauv cov hlwb hu ua melanocytes. Melanocytes tuaj yeem loj hlob ua ke los ua qhov zoo (tsis yog mob qog noj ntshav ) mus. Kev hloov pauv qhov loj me, cov duab, lossis xim ntawm lub mole tuaj yeem yog qhov cim ntawm melanoma . Melanoma tuaj yeem kho tau yog tias kuaj pom ntxov, ua ntej kis (metastasis) mus rau lwm thaj chaw ntawm lub cev.
Tsis tas li, qhov twg yog melanoma lossis carcinoma phem dua? Melanoma yog daim tawv nqaij loj mob qog noj ntshav uas pib hauv cov hlwb hu ua melanocytes. Thaum nws yog tsawg dua li basal cell mob qog noj ntshav (BCC) thiab squamous cell mob qog noj ntshav (SCC), TSO melanoma nyob deb txaus ntshai dua vim nws lub peev xwm kis mus rau lwm lub cev sai dua yog tias nws tsis kho thaum ntxov.
Hauv qhov no, qhov ua rau mob qog noj ntshav melanoma zoo li cas?
Melanomas feem ntau yog xim av lossis xim dub, tab sis qee qhov tuaj yeem tshwm liab, daj, lossis dawb. Ib txhia melanomas muaj thaj tsam nrog cov xim sib txawv, thiab lawv yuav tsis hloov pauv nyiam qub moles. Lawv tuaj yeem loj hlob sai lossis tseem kis mus rau cov tawv nqaij ib puag ncig.
Puas yog txhua yam melanomas malignant?
Melanoma yog daim ntawv mob qog noj ntshav ntawm daim tawv nqaij uas tshwm sim thaum cov xim tsim cov cell-paub tias yog melanocytes-hloov pauv thiab dhau los ua mob qog noj ntshav. Melanoma tsuas yog ib hom mob qog noj ntshav xwb. Nws tsis tshua muaj ntau dua li cov qog nqaij hlav hauv hlwb thiab squamous cell ntawm daim tawv nqaij, tab sis nws tuaj yeem ua rau muaj kev phom sij vim tias nws yuav kis tau ntau dua, lossis metastasize.
