Actinic keratosis ke boemo bo tloaelehileng ba letlalo
Actinic keratosis (AK) (e boetse e bitsoa letsatsi la letsatsi kapa mahlaseli a letsatsi) ke boemo bo tloaelehileng ba letlalo bo bakoang ke ho pepeseha ho feteletseng ho leseli la ultraviolet .
Kankere ea Letlalo ke Eng?
Kankere ea letlalo - khōlo e sa tloaelehang ea lisele tsa letlalo - hangata e hlahisa letlalo le hlakileng letsatsing. Empa mofuta ona o tloaelehileng oa kankere o ka boela oa hlaha libakeng tsa letlalo la hao eseng ka tloaelo le pepesehileng ke letsatsi.
Ho na le mefuta e meraro e kholo ea kankere ea letlalo - basal cell carcinoma, squamous cell carcinoma le melanoma.
Mabaka a Kankere ea Letlalo
Kankere ea letlalo e qala letlalong la hao la letlalo - epidermis. Epidermis ke lesela le tšesaane le fanang ka sekoahelo se sireletsang sa lisele tsa letlalo tseo 'mele oa hao o li tsoelang pele. Epidermis e na le mefuta e meraro e ka sehloohong ea lisele:
- Lisele tsa squamous li lutse ka tlaase ka ntle 'me li sebetsa joaloka letlalo la ka hare.
- Lisele tsa basal, tse hlahisang lisele tse ncha tsa letlalo, li lutse ka tlas'a lisele tse nyenyane.
- Melanocytes - e hlahisang melanine, pigment e fanang ka letlalo lebala la eona - e karolong e ka tlaase ea epidermis. Melanocytes e hlahisa melanine e eketsehileng ha u le letsatsing ho thusa ho sireletsa letlalo la hao le tebileng.
Moo kankere ea letlalo la letlalo e qalang ho khetholla mofuta oa eona le mekhoa ea hau ea phekolo
Boholo ba tšenyo ea DNA ka liseleng tsa letlalo ho bakoa ke mahlaseli a kotsi a tsoang ho ultraviolet (UV) a fumanehang khanya ea letsatsi le mabone a sebelisoang libetheng tsa ho qhibiliha.
Empa tlhahiso ea letsatsi ha e hlalosetse kankere ea letlalo e hlahang letlalong le sa tsejoeng ke letsatsi. Sena se bontša hore lintlha tse ling li ka u kenya kotsing ea kankere ea letlalo, e kang ho pepesehela lintho tse chefo kapa ho ba le boemo bo fokolisang tsamaiso ea 'mele ea hau ea ho itšireletsa mafung.
Actinic Keratosis
Li-AK li bohale bo omeletseng, bo omeletseng, bo bofubelu kapa ba pinki bo atisang ho hlahella letlalo la sefahleho - haufi le mahlo, nko, litsebeng, kapa melomo - kapa likarolo tse ling tsa 'mele tse amohelang letsatsi, joaloka ka morao ho matsoho.
Li atile haholo bathong ba nang le letlalo, ba lilemong tse bohareng kapa ba lilemong tsa bohareng, ba ka 'nang ba e-ba le leqeba le le leng kapa ba bangata.
Actinic keratosis e ka lebisa kotsing e tebileng ea squamous cell carcinoma (SCC) haeba e sa laoloe. Ho hakanngoa hore karolo ea 20 ho isa ho 40 lekholong ea li-SCC e qala e le actinic keratosis. Ha e le hantle, lingaka tse ling li lumela hore AK ke setsi sa pele sa squamous cell carcinoma. Litlhare li kenyeletsa likokoana-hloko (leqhoa), ho ts'oaroa ha ho buuoa (ho tlosoa), ho phekola (scraping), phekolo ea photodynamic kapa litlhapi tsa letlalo feela (letlalo feela) tse kang fluorouracil , diclofenac , le imiquimod . Khetho ea phekolo e itšetlehile ka sebaka sa leqeba, hore na ba bakae, le khetho ea mokuli.
Setšoantšo sa litšoantšo tsa actinic keratosis se fumaneha ho u thusa ho li khetholla.
