Thursday June 5, 2014 (foodconsumer.org) -- Vitamin C or ascorbic acid has been known to protect against a variety of cancer. A review in European Journal of Cancer provides evidence to suggest that taking vitamin C post-diagnosis can also significantly extend survival in breast cancer patients.

The review based on 10 articles of 17,696 breast cancer cases published in the PubMed database up to Feb 2014 shows that using vitamin C supplements was associated with 19% reduced risk of total mortality and 15% reduced risk of death from breast cancer.

Specifically, an additional 100-mg-per-day increase was associated with 27% reduced risk of death from all causes and 22% reduced risk of death from breast cancer.

Dietary vitamin C was also associated with significantly reduced risk of death from all causes and risk of death from breast cancer.
