Antioxidant vitamins may protect against female cancer
By Stephen Daniells, 03-Jun-2009
Increased intakes of vitamins C and E and beta-carotene may reduce the
risk of cancer of the uterus, according to a new review and
meta-analysis of the science to date.
Writing in Cancer Causes and Control, US scientists report that for
every 1,000 microgram increase per 1,000 kcal of diet of beta-carotene
was associated with a 12 per cent reduction in the risk of endometrial
cancer.
Similarly, for every 50 milligram increase per 1,000 kcal of vitamin C
the risk of endometrial cancer was reduced by 15 per cent, and for every
5 milligram increase per 1,000 kcal of vitamin E the risk of
endometrial cancer was reduced by 9 per cent.
Endometrial cancer is the fifth most common cancer among women worldwide
– around 7,000 American women die from the disease annually – but
incidence of the cancer varies more than 10-fold worldwide.
The results are based on data from 12 case-control studies, and intakes
from supplements were not considered by the researchers, led by Elisa
Bandera from the Cancer Institute of New Jersey.
Commenting on the potential mechanism, the US-based researchers noted
that antioxidant vitamins may reduce the risk of cancer by limiting
oxidative damage to DNA.

Medicine and Dentistry of New Jersey, the American Cancer Society, and
Kaiser Permanente
