Multi-cancer blood tests promise early detection, but the evidence is thin, the risks real, and they’re no substitute for listening to your body.

Some of the most dangerous cancers are the types that are hard to detect. As a result, they are often caught too late to treat. Some emerging technologies could change that in the future, with simple ...

Women with higher levels of p-tau217, a blood protein, were twice as likely to eventually develop dementia or mild cognitive impairment.

Scientists found that a blood protein called p tau217 may reveal dementia risk up to 25 years before symptoms appear.
