Cancer risk is higher in Babies with large heads
Babies born with large heads may be at an increased risk of childhood brain cancer, researchers have revealed. They said head circumference was unlikely to be a direct cause of cancer, but was probably associated with underlying causes.
One possible explanation was that hormones which affect body size also influence the development of cancer. Another theory was that large children are more prone to cancer simply because they have more cells. However there was no significant association between head size and the risk of other cancers.
