We don't know the cause of leukemia. We do know there are several things that can raise the risk for developing leukemia. Some are exposure to a lot of radiation and some chemicals.
And most people who get leukemia do not have any known risk factors. What are the symptoms? Fever and night sweats.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
