Childhood cancer is a tragedy for parents. It is the disease of the century that kills people who have just started to live. Difficult to diagnose because the child feels no pain or discomfort in the area where the tumor is located, does not add optimism in the treatment of children, because the body is still in the growth stage and simply "grows" the epicenter of cancer cell production. Because of this, in most cases children can be diagnosed with cancer only at a late stage.
