Loneliness or social isolation might lower a cancer patient's odds of survival, a new evidence review suggests.

Cancer patients who feel lonely appear to have a higher risk of death, both from their malignancy and from other health problems, researchers reported Tuesday in the journal BMJ Oncology.

Loneliness is associated with a 34% higher risk of death from any cause, data from nearly 1.6 million cancer patients in previous studies indicates, researchers found.

Loneliness also is linked to an 11% increased risk of death from cancer itself, suggests data from more than 2.1 million patients.
