Cancer May Help To Protect Us From Dementia

Dementia has been the leading cause of death in England and Wales for years now. Meanwhile, cancers are responsible for over a quarter of all deaths in the UK.

But, the journal Nature said, researchers have noticed that the two conditions are rarely seen in the same person. Cancer survival has previously been linked to an 11% decrease in dementia risk, and dementia has been associated with a 25% lower cancer risk.

That “decades”-long observation led some to think that one disease might have a protective effect on the other.
