> Childhood cancer researchers have evidence, that the first few cells of various malignancies, such as Wilms tumours, neuroblastomas, germ cells and some brain tumours may already be present at birth. This suggests that changes in certain cells of the body may have already happened in the embryo. However, much more research is needed to completely and accurately describe what causes a specific cancer in a child.
Cancer is not a contagious disease.
So far, there is no scientific evidence that childhood cancer can be caused by human behaviour. Therefore, the current state of knowledge does not allow the conclusion, that you or your child have done anything that may have caused the disease.
