La leukemia igomarara rematishu ane basa rekuumba ropa, ari maseru eropa eropa anowanikwa mu bone marrow (= zvinhu zvakapfava, zvine spongy zviri pakati pemapfupa mazhinji).

Chirwere chinowanzotanga nekusagadzikana mukuumbwa kwemasero eropa mumwongo wepfupa. Masero asina kujairika (kana leukemia masero) kuwanda uye kuwanda kwemasero akajairwa, kudzivirira kushanda kwawo kwakanaka.

Mhando dzeleukemia

Kune marudzi akawanda e leukemia. Vanogona kuverengerwa maererano nekumhanya kwekufambira mberi kwechirwere (chakanyanya kana chisingaperi) uye zvinoenderana neiyo shina masero kubva mumwongo wavanobva (myeloid kana lymphoblastic). Leukemia inowanzoreva kenza yemasero machena eropa (lymphocytes uye granulocytes, masero anokonzera utachiona), kunyange zvazvo mamwe makonzo asingawanzoitiki anogona kukanganisa masero matsvuku eropa uye maplatelet.

Acute leukemia:

Masero eropa asina kujairika haana kukura (= kuputika). Havaite basa ravo remazuva ose uye vanowanda nekukurumidza saka chirwere chinokura nekukurumidza. Kurapa kunofanira kuva nehasha uye kushandiswa nokukurumidza sezvinobvira.

Chronic leukemia:

Masero anobatanidzwa anowedzera kukura. Vanowedzera zvishoma nezvishoma uye vanoramba vachishanda kwenguva yakati. Mamwe marudzi e leukemia anogona kusaonekwa kwemakore akawanda.

Myeloid leukemia

Inokanganisa granulocytes uye masero eropa anowanikwa mumwongo. Vanogadzira masero machena eropa asina kujairika (myeloblasts). Kune marudzi maviri e myeloid leukemia :

• Acute myeloid leukemia (AML)

Ichi chimiro cheleukemia chinotanga kamwe kamwe, kazhinji kwemazuva mashoma kana mavhiki.

AML ndiyo yakajairika nzira yeacute leukemia muvachiri kuyaruka uye vechidiki vakuru.

AML inogona kutanga pazera ripi zvaro, asi inowanzokura muvanhu vakuru vane makore makumi matanhatu zvichikwira.

• Chronic myelo native leukemia (CML)

La chisingaperi myelogenous leukemia anonziwo chisingaperi myelocytic leukemia ou chisingaperi granular leukemia. Mhando iyi yeleukemia inokura zvishoma nezvishoma, nekufamba kwemwedzi kana makore. Zviratidzo zvechirwere zvinoonekwa sezvo huwandu hwemasero eukemia muropa kana bhonzo hunowedzera.

Ndiyo inowanzozivikanwa yechirwere chechirwere cheukemia muvanhu vakuru pakati pemakore 25 ne60. Dzimwe nguva hazvidi kurapwa kwemakore akawanda.

Lymphoblastic leukemia

Lymphoblastic leukemia inokanganisa lymphocytes uye inogadzira lymphoblasts. Kune marudzi maviri e lymphoblastic leukemia:

• Acute lymphoblastic leukemia (ZVESE)

Ichi chimiro cheleukemia chinotanga kamwe kamwe uye chinofambira mberi nekukurumidza kwemazuva mashoma kana mavhiki.

Yakadanwa zvakare acute lymphocytic leukemia ou acute lymphoid leukemia, ndiyo inowanzozivikanwa yeleukemia muvana vaduku. Kune akati wandei ma subtypes emhando iyi yeleukemia.

• Chronic lymphoblastic leukemia (CLL)

Ichi chimiro cheleukemia chinowanzobata vanhu vakuru, kunyanya pakati pemakore 60 ne 70. Vanhu vane chirwere ichi vanogona kunge vasina kana zviratidzo zvishomanana kwemakore uye vozova nechikamu umo masero eukemia anokura nokukurumidza.

Zvinokonzera leukemia

Zvikonzero zveleukemia hazvisati zvanyatsonzwisiswa. Masayendisiti anobvuma kuti chirwere ichi chisanganiswa chemajini uye zvakatipoteredza.

Kuwanda

MuCanada, mumwe muvarume 53 uye mumwe muvakadzi 72 vachava neleukemia muupenyu hwavo hwose. Muna 2013, zvinofungidzirwa kuti 5800 vekuCanada vachakanganiswa. (Canadian Cancer Society)

MuFrance, leukemia inobata vanhu vanosvika makumi maviri gore rega rega. Leukemia inosvika 20% yekenza dzevana, 000% yeacute lymphoblastic leukemias (ALL).

Kuongororwa kwe leukemia

Kuongorora ropa. Kuongorora sampuli yeropa kunogona kuona kana mazinga emasero machena eropa kana maplatelet asina kunaka, zvichireva leukemia.

Bone marora bhiopsy. Muenzaniso wemwongo wakabviswa kubva muhudyu unogona kuona humwe hunhu hwemasero eukemia hunogona kuzoshandiswa kuratidza sarudzo dzekurapa kwechirwere.
