Hi vithi
Welcome to HealthcareMagic.
Blood
cancer is of many types depend on the
cell of origin.For first stage of
leukemia that probably could have occurred in your friend , drugs treatment can be the choice.I advise him to adhere properly with the treatment and take adequate diet even if he has low
appetite.I also advise him to take wheat grass juice which is useful in improving blood function along with diet.
Take care.
