Umdlavuza wegazi

I-leukemia wuhlobo lomdlavuza wegazi oqala emnkantsheni wethambo. Umnkantsha wethambo yizicubu ezithambile ezisenkabeni yamathambo, lapho kwenziwa khona amangqamuzana egazi.

Igama elithi leukemia lisho igazi elimhlophe. Amaseli egazi amhlophe (ama-leukocyte) asetshenziswa ngumzimba ukulwa nezifo nezinye izinto zangaphandle. Ama-leukocyte enziwa emnkantsheni wethambo.

Umdlavuza wegazi uholela ekwandeni okungalawulwa kwenani lamaseli amhlophe egazi.

Amaseli anomdlavuza avimbela amaseli abomvu anempilo, ama-platelets, namaseli amhlophe avuthiwe (ama-leukocyte) enziwa. Izimpawu ezisongela impilo zingakhula lapho amaseli egazi ejwayelekile encipha.

Amaseli womdlavuza angasakazeka egazini nasezikhungweni ze-lymph. Bangakwazi nokuya ebuchosheni nasentanjeni yomgogodla (uhlelo oluphakathi lwezinzwa) nakwezinye izingxenye zomzimba.

Umdlavuza wegazi ungathinta izingane nabantu abadala.

AmaLeukemi ahlukaniswe izinhlobo ezimbili ezinkulu:

• Okuhle (okuqhubeka ngokushesha)
• Okungapheli (okuqhubeka kancane kancane)

Izinhlobo eziyinhloko ze-leukemia yilezi:

• I-leukemia enamandla ye-lymphocytic (BONKE)
• I-leukemia enamandla kakhulu (AML)
• I-lymphocytic leukemia engapheli (CLL)
• I-leukemia engapheli yomzimba (CML)

• Ukufiswa komnkantsha wethambo
• I-acute lymphocytic leukemia - i-photomicrograph
• Izinduku ze-Auer
• I-lymphocytic leukemia engapheli - umbono omncane
• I-myelocytic leukemia engapheli - umbono omncane
• I-leukemia engapheli ye-myelocytic
• I-leukemia engapheli ye-myelocytic
