Iwo 5 Akanyanya Kuzivikanwa Kenza Risk Factors muKatsi

Makatsi edu ari kuchembera. Zvakanaka, hongu, nokuti zvinokupa nguva yakawanda pamwe chete. Nekudaro, sezvo tarisiro yehupenyu inowedzera, katsi zvakare dzine njodzi huru yekubatwa negomarara.

Muchidimbu, kenza inogona kuitika mumakati ezera ripi zvaro. Zvisinei, mhuka dzakura dzine ngozi yakawedzera yekenza: Maererano nenhamba, 50 muzana yekatsi dzose dzine makore anopfuura 10 dzinova nekenza. Ndosaka zvichinyanya kukosha kuti uendese katsi dzechikuru kuna chiremba anotariswa mwedzi mitanhatu yega yega kuitira kuti akwanise kuona gomarara nguva ichiripo.

Kukura kwemamota kunoratidzwawo kufarirwa mumakati eese mazera nezvinhu zvishanu zvinotevera:

Passive Kusvuta

Kusvuta kusingadzoreki kunowedzera njodzi yekenza yekatsi zvakanyanya! Imwe ongororo yakawana kuti njodzi yekenza yemapapu mumakati anogara mumhuri inosvuta yaive yakapetwa ka2.4 kupfuura mumakatsi anogara mudzimba dzisina kuputa. Mukati dzaive dzakafumurwa kusvuta kwemakore mashanu kana kupfuura, njodzi yakawedzera 5-fold (BERTONE et al., 3.2).

Sunlight

Kuratidzwa kune mwenje weUV kunogona kuita basa rakakosha mukuvandudza squamous cell carcinoma. Chidzidzo cheAmerica chakaratidza kuti katsi chena muCalifornia dzaive ne13.4 nguva yakakwira mukana wekuita bundu reganda rakashata kupfuura kitsi dzine majasi ane pigmented (DORN et al., 1971). Chidzidzo chakazotevera chakasimbisa kuti katsi zhinji dzine squamous cell carcinoma dzine machena machena (LANA et al., 1997).

Kuti dzizvidzivirire, kunyanya katsi chena hadzifanire kupedza nguva yakawanda dziri muzuva, kunyanya pakati pa10am na 2pm apo zuva rinenge riri pamusoro uye mwaranzi waro uchinyanya kukuvadza. Kana katsi iri kunze uye inenge yakawanda mukati mezuva, nzeve nemhino zvinofanira kuve nekrimu ne sunscreen yakakodzera makati. Kune vanamati vezuva pahwindo sill, zvakakosha kutenga firimu rekudzivirira zuva regirazi.

Trauma uye Chronic Inflammation

Zvese zviri zviviri kukuvadzwa uye kuzvimba kusingaperi zvinogona kusimudzira kukura kwemasarcoma, kureva mamota akaipa emubatanidzwa, anotsigira kana mhasuru. Semuenzaniso, chidzidzo chakaratidza kuti 13 katsi dzine ocular tumorous shanduko dzakatambura nezvirwere zvemaziso munguva yakapfuura (DUBIELZIG et al., 1990). Mune imwe ongororo, mana kubva pa4 katsi ane cancer yemapfupa akawanikwa akadzokera kune kuputsika kwakarapwa neosteosynthesis (KESSLER et al., 36).

Kuzvimba kunoitawo basa rakakosha mukukura kwebundu, semuenzaniso mune feline jekiseni-yakabatana fibrosarcoma (FISS). Subcutaneous uye intramuscular jekiseni inogona kukonzera kusingaperi kuzvimba mumakati, izvo zvinogona kufambira mberi kusvika kuFISS (HAUCK, 2003).

Zvirwere Zvirwere

Feline immunodeficiency virus (FIV) uye feline leukemia virus (FeLV) zvakakosha zvinokonzera njodzi mukukura kwe lymphoma (mamota e lymphoid tissue). Katsi dzinobata zvakanaka dzinoita ka60 mukana wekuita lymphoma pane katsi FeLV-negative conspecifics. Panyaya yekatsi dzine utachiona hweFIV, mukana wekuita bundu rakapetwa kashanu kusvika katanhatu (SHELTON et al., 1990).

Mahomoni

Mahomoni anoita basa mukukura kwefeline mammary carcinomas (gomarara rezamu) risingafaniri kurerutswa. Katsi dzechikadzi dzisina unneutered dzinorwara kakawanda kupfuura ekare-neutered echikadzi katsi. Queens akabatwa asati asvika mwedzi mitanhatu yekuzvarwa ane 6% yakaderera yengozi yegomarara rezamu pane mambokadzi asina kuberekwa. Kana isina kubviswa pakati pemakore emwedzi ye91 uye gore re6, njodzi inoderedzwa ne1% (OVERLEY et al., 86).

Kugara kwekutonga kweprogestins ("piritsi rekatsi"), semuenzaniso kudzvinyirira kupisa, kunobatanidzwa nekuwedzera kwengozi yekenza yemazamu mumakati echikadzi. Nekudaro, izvi hazviratidzike kunge zvakadaro kana kutonga kuchiitika nguva nenguva (MISDORP et al., 1991).
