Is leukemia terminal?

No necessarily: Long time ago that was true. But the modern treatments for leukemias are quite effective and are often curative. But the treatment is best done at a cancer center where you can find experienced leukemia specialists especially if it is an acute leukemia(as opposed to chronic leukemias which are less serious and easier to treat).

Survival among ...: Leukemia patients is influenced by many things, including phenotype, molecular features, presenting white count, patient age, etc. We are making strides every day, with survival improvements across the board, so no, a leukemia diagnosis does not mean you should give up hope for a long and meaningful survival. Be hopeful as you move forward. Good luck.
