Cov qog nqaij hlav cancer yog hlwb uas faib relentlessly, tsim cov qog nqaij hlav los yog dej nyab cov ntshav uas txawv txav hlwb . Cell Kev faib tawm yog cov txheej txheem ib txwm siv los ntawm lub cev rau kev loj hlob thiab kho. Noj qab nyob zoo hlwb txhob muab faib thaum tsis xav tau tus ntxhais ntxiv lawm hlwb , tab sis cov qog nqaij hlav cancer txuas ntxiv tsim cov ntawv luam.
Tib neeg kuj nug, peb txhua tus puas muaj cov qog nqaij hlav cancer?
Cancer tuaj yeem pib yuav luag txhua qhov chaw hauv tib neeg lub cev, uas yog ua los ntawm trillions ntawm hlwb . Feem ntau, tib neeg hlwb loj hlob thiab faib los tsim tshiab hlwb raws li lub cev xav tau lawv. Thaum twg hlwb loj hlob los yog puas, lawv tuag, thiab tshiab hlwb coj lawv qhov chaw. Thaum twg mob qog noj ntshav txhim kho, txawm li cas los xij, cov txheej txheem kev ua haujlwm no tawg.
Ib sab saum toj no, cov cell ib txwm thiab cov qog nqaij hlav txawv li cas? Cell kho thiab ntawm tes tuag- Li qub yog kho lossis tuag (mob apoptosis) thaum lawv puas lossis laus. Cov qog nqaij hlav cancer tsis kho lossis tsis raug apoptosis. Muaj peev xwm Metastasize (Tshaj)- Li qub nyob hauv thaj tsam ntawm lub cev uas lawv nyob.
Ib tug kuj yuav nug, puas hlwb qog nqaij hlav cancer?
Mob qog noj ntshav : Yuav Ua Li Cas Lawv Pib thiab Yam Ntxim Saib Ntxim Ua. Cov qog nqaij hlav cancer txawv ntawm qhov qub hlwb nyob rau hauv lub cev nyob rau hauv ntau txoj kev. Li qub hlwb ua mob qog noj ntshav thaum ib tug series ntawm mutations coj tus ntawm tes txuas ntxiv kev loj hlob thiab faib tawm ntawm kev tswj hwm, thiab, hauv ib txoj kev, a mob qog noj ntshav yog a ntawm tes uas tau ua tiav ib hom kev tsis txawj tuag.
Mob qog noj ntshav zoo li cas?
Qhov loj thiab cov duab ntawm lub nucleus ntawm a mob qog noj ntshav feem ntau txawv txav. Feem ntau, cov nucleus ntawm a mob qog noj ntshav loj dua thiab tsaus dua li qhov ib txwm muaj ntawm tes thiab nws qhov loj tuaj yeem sib txawv heev. Lub nucleus los ntawm a mob qog noj ntshav Nws loj dua thiab tsaus dua vim nws feem ntau muaj DNA ntau dhau.

Yuav ua li cas feem pua ntawm cov qog nqaij hlav qog nqaij hlav qog noj ntshav?
Kev Kho Mob: Kev kho hluav taws xob
Vim li cas cov qog nqaij hlav cancer sib faib sai dua li cov qog ib txwm?
Cov hlwb li qub tuaj yeem kho lawv tus kheej yog tias lawv cov noob puas lawm. Qhov no hu ua kev kho DNA. Cov noob caj noob ces tshiab, lossis kev hloov pauv, tuaj yeem ua rau cov qog nqaij hlav cancer loj hlob sai, kis mus rau lwm qhov hauv lub cev, lossis ua rau muaj kev tiv thaiv kev kho mob. Cov qog nqaij hlav cancer tuaj yeem tsis quav ntsej txog cov cim qhia uas qhia lawv tus kheej kom puas tsuaj
Yuav ua li cas ntxiv mutations muab cov qog nqaij hlav cancer kom zoo dua?
Mob qog noj ntshav tsis tau kuaj xyuas cov cell loj hlob. Kev hloov pauv hauv cov noob tuaj yeem ua rau mob qog noj ntshav los ntawm kev ua kom nrawm ntawm cell faib cov nqi lossis inhibiting ib txwm tswj ntawm lub cev, xws li kev kaw lub voj voog ntawm tes lossis programmed cell tuag. Raws li pawg loj ntawm cov qog nqaij hlav cancer loj tuaj, nws tuaj yeem tsim ua qog
Puas yog cov qog nqaij hlav qog nqaij hlav nyuaj?
Shotty feem ntau siv los piav txog qhov kev xav ntawm cov qog nqaij hlav (cov qog qog nqaij hlav) thaum lawv palpated (xws li) los ntawm daim tawv nqaij. 'Shotty' lymph nodes yog cov uas tsis yog nyuaj thiab puag ncig tab sis kuj me me thiab tsis muaj qhov tshwm sim
Puas yog qog nqaij hlav qog lossis cov qog ua kua?
Ib qho txawv txav ntawm cov ntaub so ntswg uas feem ntau tsis muaj cov hlwv lossis cov kua dej. Cov qog nqaij hlav tuaj yeem yog benign (tsis yog mob qog noj ntshav), lossis malignant (cancer). Piv txwv ntawm cov qog nqaij hlav yog sarcomas, carcinomas, thiab lymphomas. Leukemias (cov ntshav qog ntshav) feem ntau tsis tsim cov qog nqaij hlav
