No, it's not acute lymphoblastic leukaemia.

Both acute lymphoblastic leukaemia and non-Hodgkin's lymphoma can be fatal; however, as they are both malignancies of the immune system and therefore immunocompromise the patient, it's normally not the malignancy that leads to the patient's demise, but something else, such as an infection, that the patient acquires and can't shake off.

So, one of these two diseases might be the underlying cause of death, but they're not actually what killed the patient.

Try again.
