Does leukemia go away easily?

Well, chemotherapy is a very effective treatment, but it doesn't work for everyone. So, in a case like your grandmothers. Like the first answerer said. It depends on how advanced the leukemia is. If it is in stage 4, then she is most likely not to survive. But, if its in stage 0. Which is when the disease first develops then, it can be treated effectively. I hope your grandmother comes out okay :D
