Research from Rutgers Cancer Institute of New Jersey and and
other U.S. health and academic institutions shows a diet high in calcium and
low in lactose (milk) may reduce the risk of ovarian cancer in African-American
women. The work, which appears in the latest edition of the British Journal of Cancer, also found sun exposure in the summer months may
reduce the risk of developing the disease in this population.
Ovarian cancer is the fifth leading cause of cancer death
among women in the U.S., according to the National Cancer Institute.
The associations were evaluated among participants in the
African-American Cancer Epidemiology Study, which is an on-going
population-based case-control study of ovarian cancer in African-American women
in 11 states including New Jersey.
Investigators found that both lactose intake and consumption
of whole milk were significantly associated with an increased risk of ovarian
cancer risk in African-American women, while skim and low-fat milk were not. No
association was found for cheese or yogurt products.
Calcium intake, whether through food and/or supplement, was
associated with a decreased risk of disease. While researchers found no
association between dietary and supplemental vitamin D intake and ovarian
cancer risk.
Results also showed that increased sun exposure may reduce
ovarian cancer risk in this population.
