Qhov kev pheej hmoo poob qis hauv cov hnub nyoog nruab nrab, tab sis nce ntxiv rau cov neeg laus (feem ntau muaj hnub nyoog tshaj 60 xyoo).
osteosarcoma txhim kho li cas?
Osteosarcoma pib thaum cov pob txha noj qab haus huv hloov pauv hauv nws cov DNA Ib lub cell DNA muaj cov lus qhia uas qhia lub cell yuav ua li cas. Cov kev hloov pauv qhia lub cell pib tsim cov pob txha tshiab thaum nws tsis xav tau. Qhov tshwm sim yog qhov loj (cov qog) ntawm cov pob txha tsim tsis zoo uas tuaj yeem cuam tshuam thiab rhuav tshem cov nqaij mos ntawm lub cev.
