Actinic keratosis inowanzochengetedza ganda mamiriro ezvinhu
Actinic keratosis (AK) (iyo inonziwo solar keratosis kana kuti mavara ezuva) inowanzochengetedza ganda rinokonzerwa nokusuruvara kwakanyanya kune ultraviolet chiedza .
Chii Chirwere Cheganda?
Kenza yeropa - kukura kusina kuchena kwemasero eganda - kazhinji kunowedzera paganda rinoratidzwa zuva. Asi chimiro ichi chinozivikanwa chekenza chinogonawo kuitika kune dzimwe nzvimbo dzeganda rako risingawanzobudiswi nezuva.
Kune mhando mitatu yakakura yekenza yeganda - basal cell carcinoma, squamous cell carcinoma uye melanoma.
Zvinokonzera Ganda Kanzera
Kenza yepachira inotanga mucheka rako guru-epidermis. Iyo epidermis isimbi yakatetepa inopa chidziviriro chekuchengetedza chemasero eganda ayo muviri wako unoramba uchinyatsobudisa. Epidermis ine mitatu mikuru yemasero:
- Masero ane masimba anongogara pasi pekunze uye anoita seganda remukati.
- Basal cells, izvo zvinogadzira masero matsva eganda, vanogara pasi pemasero ane tsvina.
- Melanocytes - iyo inogadzira melanin, iyo pigment inopa ganda rayo yakajeka ruvara - iri munharaunda yepidermis yako. Melanocytes inowedzera melanin kana iwe uri muzuva kuti ubatsire kudzika kwepakati peganda rako.
Apo kenza yako yeganda inotanga inogadzira rudzi rwayo uye nzira dzako dzokurapa.
Zvakawanda zvinokonzerwa neDNA mumasero eganda zvinokonzerwa nemirairo ye ultraviolet (UV) inowanikwa muzuva uye mumagetsi anoshandiswa mumabhedha ekuchenesa.
Asi kutarisa kwezuva hakutsananguri ganda rekenza rinokura paganda risingatongoratidzirwa nezuva. Izvi zvinoratidza kuti zvimwe zvikonzero zvinogona kuita kuti uwane kenza yekenza yeganda, yakadai sekusvibiswa kune zvinodhaka kana kuva nemamiriro ezvinhu anoita kuti utachiona hwako hudzivirire.

Actinic keratosis inogona kutungamirira kune zvakakomba zvinokonzera squamous cell carcinoma (SCC) kana isina kusiyiwa. Inofungidzirwa kuti 20 kusvika ku40 muzana yeSCC inotanga se actinic keratosis. Ichokwadi, vamwe vanachiremba vanodavira kuti AK ndiyo chaiyo yekutanga kwe squamous cell carcinoma. Mishonga inosanganisira zvipembenene (kufuta), kushandiswa kwekuvhiya (kubviswa), curettage (scraping), chirwere chephotodynamic kana mutsara (ganda-chete) zvinokonzera zvakadai se fluorouracil , diclofenac , uye imiquimod . Chisarudzo chekurapa chinoenderana nenzvimbo yechiremera, kuti vangani varipo, uye kusarudzwa kwemurwere.
