Actinic keratosis ndi wamba wamba wa khungu
Actinic keratosis (AK) (yotchedwa dzuwa keratosis kapena mawanga a dzuŵa) ndi wamba wamba umene umapezeka chifukwa cha kuunika kwa ultraviolet .
Kodi Khansa Yamtundu N'chiyani?
Khansara ya khungu - kukula kosalekeza kwa maselo a khungu - nthawi zambiri kumakhala khungu lomwe limawonekera ku dzuwa. Koma mtundu uwu wamba wa khansara ukhozanso kuchitika kumalo a khungu lanu osati kawirikawiri ndi dzuwa.
Pali mitundu itatu yaikulu ya khansa yapakhungu - basal cell carcinoma, squamous cell carcinoma ndi melanoma.
Zifukwa za khansa ya khungu
Khansara ya khungu imayamba m'kati mwa khungu lanu - epidermis. Epidermis ndi gawo lochepa kwambiri lomwe limapereka chivundikiro chotetezera maselo a khungu omwe thupi lanu limapitiriza. Epidermis ili ndi mitundu ikuluikulu itatu ya maselo:
- Maselo a squamous ali pansi pamtunda ndipo amagwira ntchito monga khungu la mkati.
- Maselo a basal, omwe amapanga maselo atsopano a khungu, amakhala pansi pa maselo osakanikirana.
- Melanocytes - yomwe imabala melanin, mtundu umene umapatsa khungu mtundu wake - uli m'munsi mwa epidermis. Ma Melanocytes amapanga melanin kwambiri mukakhala padzuwa kuti muteteze zigawo zakuya za khungu lanu.
Kumene kansalu khungu lanu limayambira kumayambitsa mtundu wake ndi njira zomwe mungasankhire.
Zambiri mwa kuwonongeka kwa DNA m'maselo a khungu zimachokera ku mazira a ultraviolet (UV) omwe amapezeka kuwala kwa dzuwa komanso m'magetsi ogwiritsidwa ntchito m'mabedi opukuta.
Koma kutuluka kwa dzuwa sikufotokoza za khansa ya khungu imene imakhala pakhungu osati kawirikawiri yomwe imakhala kuwala kwa dzuwa. Izi zikusonyeza kuti zina zikhoza kukupangitsani kadosa ya khungu, monga kukhala ndi poizoni kapena kukhala ndi chizolowezi chofooketsa chitetezo chanu cha mthupi.
Actinic Keratosis
AK ali ndi ziphuphu zolimba, zouma, zonyezimira kapena za pinki zomwe zimawoneka pamaso pa nkhope - pafupi ndi maso, pamphuno, m'makutu, kapena pamilomo - kapena mbali zina za thupi zomwe zimalandira kuwala kwa dzuwa, monga kumbuyo kwa manja.
Amakonda kwambiri anthu okalamba, okalamba kapena okalamba omwe angathe kukhala ndi vuto limodzi kapena ambiri.
Actinic keratosis ikhoza kutsogolera mchitidwe woopsa kwambiri wa squamous cell carcinoma (SCC) ngati sunatsatire. Akuti 20 mpaka 40 peresenti ya SCC amayamba monga actinic keratosis. Ndipotu, madokotala ena amakhulupirira kuti AK kwenikweni ndi khungu la squamous cell carcinoma. Mankhwala amaphatikizapo mankhwala opangira mafinya (kuzimitsa), kusakaniza opaleshoni (kuchotsa), kupopera (scraping), mankhwala opangira photodynamic kapena mankhwala opangira khungu ( fluorouracil , diclofenac , ndi imiquimod) . Kusankhidwa kwa chithandizo kumadalira malo a zilonda, ndi angati alipo, ndi kusankha kwa wodwalayo.
Chithunzi chojambula cha zithunzi za actinic keratosis chilipo kuti chikuthandizeni kuzindikira.
