Kenza yeTiroid: chii icho?
Gomarara rethyroid igomarara risingawanzoitiki. Kune 4000 zviitiko zvitsva muFrance pagore (kune makumi mana emazamu egomarara). Inobata vakadzi pa 40%. Chiitiko chayo chiri kuwedzera munyika dzose.
MuCanada muna 2010, gomarara rethyroid rakaonekwa mune angangoita murume 1 uye 000 vakadzi. Gomarara iri rinouya kuma4e chiyero chegomarara revakadzi (4,9% yezviitiko), asi inongoverengera 0,3% yekufa kwegomarara muvakadzi. the chirwere Kazhinji inowanikwa muvanhu vari pakati pemakore 25 ne65.
Gomarara iri rinowanzoonekwa nguva ichiripo. Mushonga wacho unobva wanyatsoshanda nekurapa mu90% yezviitiko. Maitiro ekuongorora akavandudzwa anogonawo kutsanangura kuti nei kuongororwa kuchiwanzo. Zvamazvirokwazvo, zvino tinogona kuona tupundu tuduku twaichimbova tusingaoneki.
Zvinhu zvinotyisa
Gomarara regomarara rinosimudzirwa nekufumurwa kwegomarara remwaranzi, kungave kubva mukurapwa neradiation kuenda kumusoro, mutsipa kana chipfuva chepamusoro, kunyanya muhudiki, kana nekuda kwekudonha kweradioactive munzvimbo dzakaitwa bvunzo dzenyukireya, kungave mushure metsaona yenyukireya. zvakadai sepaChernobyl.

Mhando dzakawanda dzegomarara
Iyo thyroid inoumbwa nemhando nhatu dzemasero: follicular masero (ayo secrete thyroid mahormone), parafollicular masero ari pedyo navo uye secreting calcitonin (inobatanidzwa mu calcium metabolism), pamwe chete nemasero asina ruzivo (anotsigira tishu kana tsinga dzeropa) .
Cancers inokura kubva mufollicular masero mune anopfuura 90% ezviitiko; zvichienderana nekuonekwa kwemasero egomarara, tinotaura nezvegomarara repapillary (mune 8 kubva mugumi zviitiko) kana vesicular cancers. Aya magomarara anokura zvishoma nezvishoma uye anonzwa neradioactive iodine kurapwa.
Zvizhinji kashoma (10% yezviitiko), kenza yemedullary inokura kubva kumaseru eparafollicular kana kubva kumaseru asina kukura, aya mapundu achinzi haana mutsauko kana anaplastic. Muzongoza negomarara reanaplastic rinokura nekukurumidza uye rinonyanya kunetsa kurapa.
