Sunday 03/21/2021 (jkzx.com) — A recent review published recently shows that vitamin supplementation after diagnosis can moderately reduce the risk of total death risk, death from cancer and cancer recurrence.
For instance, calcium supplementation was linked to a 12% reduction in total death and 29% reduced risk of cancer mortality among all cancer patients. The risk reduction in cancer mortality was particularly significant among colorectal cancer survivors – 34%.
Vitamin D also helps cancer survival. Vitamin D supplementation was correlated with a 14% reduction in total mortality among cancer patients.
For breast cancer survivors, supplementation with vitamin C, D and E was linked to 21%, 15% and 24% reduced risk of total mortality, respectively.
Even multivitamins helps cancer survival. The review finds multivitamins cut risk of lower cancer recurrence by 24%, vitamin C by 34% and vitamin E by 31%.
However, authors caution that all data were generated from observational studies. To confirm the benefits from vitamin supplementation in cancer patients, trials need to be conducted.
Indeed, it remains largely unknown if those vitamin users take any other potent anticancer alternative phytochemicals such as curcumin, EGCG, resveratrol, Genistein, and sulforaphane. However, some trials have found vitamin supplements do help all cancer patients to extend their survival time.
