Vitamin C and survival among women with breast cancer: a meta-analysis.
This summary analysis examined the results of 10 studies on the relationship between the intake of vitamin C, either from dietary supplements or the diet itself, and the death rate from breast cancer. Total mortality was also examined. The analysis included data from nearly 18,000 breast cancer patients.The results suggest that a high dietary intake of vitamin C was associated with a lower mortality rate for breast cancer as well as a lower overall death rate. Further details can be found in the study.
