Fruits, vegetables prevent invasive cervical cancer

The U.S. Centers for Disease Control and Prevention reported not long ago that no more than 26 percent of adults in the country eat vegetables three times day.  

Eating fruit and vegetables is believed to provide a range of benefits including lowering the risk of a variety of cancers such as cervical cancer.

A new study published in the Sept 17 2010 issue of International Journal of Cancer suggests eating large amounts of fruits and vegetables help reduce risk of invasive cervical cancer, and probably in-situ carcinoma as well.

The study led by González C.A. and colleagues from Catalan Institute of Oncology, Barcelona (ICO-IDIBELL), Spain shows however that eating fruits and vegetables did not seem to cut the risk of in-situ carcinoma as significantly.

Some dietary factors could be involved as co-factors in cervical carcinogenesis, according to the background information in the study report. But the current study was meant to examine the effect of intake of fruits and vegetables on cervical cancer.

For the study, the researchers looked at data from a prospective 9-year study of 299,649 women enrolled in the European Prospective Investigation Into Cancer and Nutrition study and found eating fruit and vegetables was generally associated with reduced risk of invasive cervical cancer.

Specifically, increasing daily intake of fruits by 100 grams was associated with 17 percent reduced risk of invasive cervical cancer. This was compared to a 15 percent reduction in the risk of invasive cervical cancer for increasing intake of vegetables by 100 grams.

Statistically non-significant inverse  associations were found between leafy vegetables, root vegetables, garlic, onion, citrus fruits, vitamin C,  vitamin E, and retinol and risk of invasive cervical cancer.  No associations were found between beta-carotene, vitamin D and folic acid and invasive cervical cancer.

The researchers concluded "Our study suggests a possible protective role of fruit intake and other dietary factors on ISC, that need to be confirmed on a larger number of ISC cases."
