Nwamba anyị na-akawanye nká. Nke ahụ dị mma, n'ezie, n'ihi na ọ na-enyekwu gị oge ọnụ. Otú ọ dị, ka atụmanya ndụ na-abawanye, nwamba nwekwara ohere dị elu nke ịmalite ọrịa cancer.
Na ụkpụrụ, ọrịa cancer nwere ike ime na nwamba nke afọ ọ bụla. Otú ọ dị, anụmanụ ndị meworo agadi na-enwewanye ohere nke ọrịa cancer: N'ịkọ akụkọ, pasent 50 nke nwamba niile karịrị afọ 10 na-ebute ọrịa kansa. Ọ bụ ya mere o ji dị mkpa ka a na-ebute nwamba ndị agadi n'ebe a na-enyocha anụ ụlọ ma ọ dịkarịa ala ọnwa isii ọ bụla iji chọpụta ọrịa kansa nwere ike ịmalite.
A na-egosikwa na mmepe nke etuto ahụ nwere mmasị na nwamba nọ n'afọ ọ bụla site na ihe ise ndị a:
Ịṅụ sịga na-agafe agafe
Ịṅụ sịga na-agafe agafe na-abawanye ohere nke ọrịa cancer maka nwamba nke ukwuu! Otu nnyocha chọpụtara na ihe ize ndụ nke ọrịa cancer akpa ume na nwamba bi n'ụlọ a na-ese anwụrụ ji okpukpu 2.4 karịa nke nwamba bi n'ụlọ ndị na-adịghị ese anwụrụ. N'ime nwamba ndị ekpughere anwụrụ ọkụ maka afọ 5 ma ọ bụ karịa, ihe ize ndụ ahụ mụbara 3.2-fold (BERTONE et al., 2002).
Uwa anyanwụ
Ikpughe na ọkụ UV nwere ike ịrụ ọrụ dị oke mkpa na mmepe nke carcinoma cell squamous. Nnyocha e mere n'America gosiri na nwamba ọcha na California nwere ihe ize ndụ dị elu ugboro 13.4 nke ịmepụta akpụ akpụkpọ anụ karịa nwamba nwere uwe mkpuchi pigmenti (DORN et al., 1971). Nnyocha e mechara gosi na ọtụtụ nwamba nwere carcinoma squamous cell nwere ikpe ọcha (LANA et al., 1997).
Maka nchebe nke onwe ha, nwamba na-acha ọcha karịsịa ekwesịghị itinye oge dị ukwuu na anyanwụ, karịsịa n'etiti 10am na 2pm mgbe anyanwụ kacha elu ma ụzarị ya na-emerụ ahụ. Ọ bụrụ na pusi na-apụ na ihe dị ka ọtụtụ n'ụbọchị, ntị na imi kwesịrị ka a na-ekpuchi ya na sunscreen kwesịrị ekwesị maka nwamba. Maka ndị na-efe anyanwụ na windo windo, ọ bara uru ịzụta ihe nkiri nchebe anyanwụ maka iko.
Ọnyà na Mbufụt na-adịghị ala ala
Ma trauma na mbufụt na-adịghị ala ala nwere ike ịkwalite mmepe nke sarcomas, ntụgharị ụbụrụ ọjọọ nke njikọta, nkwado ma ọ bụ anụ ahụ. Dịka ọmụmaatụ, otu nnyocha gosiri na nwamba 13 nwere mgbanwe ụbụrụ anya na-arịa ọrịa anya n'oge gara aga (DUBIELZIG et al., 1990). N'ọmụmụ ihe ọzọ, 4 n'ime 36 nwamba nwere ọrịa cancer ọkpụkpụ laghachiri na mgbaji a na-emeso osteosynthesis (KESSLER et al., 1997).
Mbufụt na-ekerekwa òkè dị mkpa na mmepe tumor, dịka ọmụmaatụ na feline injection-associated fibrosarcoma (FISS). Ngwunye nke subcutaneous na intramuscular nwere ike ime ka ọnya na-adịghị ala ala na nwamba, nke nwere ike ịga n'ihu na FISS (HAUCK, 2003).
Ọrịa Viral
Feline immunodeficiency virus (FIV) na feline leukemia virus (FeLV) bụ ihe dị mkpa dị ize ndụ na mmepe nke lymphoma (akpụ nke lymphoid anụ ahụ). Nwamba dị mma nwere ike ịmalite lymphoma ugboro 60 karịa nwamba FeLV-negative conspecific. N'ihe gbasara nwamba nwere FIV, ohere nke ịmepụta etuto ahụ dị okpukpu ise ruo isii karịa (SHELTON et al., 1990).
Hormones
Hormones na-ekere òkè na mmepe nke feline mammary carcinomas (ọrịa ara ara) nke a na-ekwesịghị ilele anya. Nwamba nwanyị na-enweghị oghere na-adakarị ọrịa karịa nwamba nwamba ndị na-anọpụghị n'oge. Queens spayed tupu ọnwa 6 eruo nwere 91% ihe ize ndụ nke ọrịa ara ara karịa ndị eze nwanyị na-enweghị njikọ. Ọ bụrụ na etinyere n'etiti afọ nke ọnwa 6 na otu afọ, ihe ize ndụ ahụ na-ebelata site na 1% (OVERLEY et al., 86).
Nlekọta oge niile nke progestins ("ọgwụ maka pusi"), dịka ọmụmaatụ iji gbochie okpomọkụ, jikọtara ya na nnukwu ihe ize ndụ nke ọrịa ara ara na nwamba nwanyị. Agbanyeghị, nke a apụtaghị na ọ bụ ikpe mgbe nchịkwa na-adị mgbe ụfọdụ (MISDORP et al., 1991).
