Depends on stage. Like any other cancer, cervical cancer survival is closely linked to early detection and treatment. The more extensive the spread of the cancer the more likely it is to kill you.
100% If you have cervical cancer and it is not treated, it is 100% certain that it will kill you unless something else does first. If you have preinvasive cervical cancer and it is treated, it is 100% certain not to kill you (unless another one forms, so keep up the surveillance.) in the poor nations, several % of young women can expect to die of cancer of the cervix.
