Hi, dear I have gone through your question. I can understand your concern. Most of the time genetic mutations are the cause. You can not get rid of that. Just go for regular monitoring of blood count. So that you can detect any recurrence in early stage. Hope I have answered your question, if you have any doubts then contact me at bit.ly/Drsanghvihardik, I will be happy to answer you. Thanks for using health care magic. Wish you a very good health.
