TUESDAY, April 3 (HealthDay News) -- Taller, heavier women may
be at an increased risk of ovarian cancer, research suggests.
An international research group examined data from 47 studies
conducted in 14 countries involving more than 25,000 women with
ovarian cancer and 81,000 women without the disease.
Every 2-inch increase in a woman's height was associated with a
significant increase in the odds of developing ovarian cancer, the
investigators found. A higher body mass index (a measurement based
on height and weight) also was associated with a higher risk of
ovarian cancer, but only among women who had never taken menopausal
The researchers found that the association between height and
weight and ovarian cancer remained even after taking into account
other factors that could influence ovarian cancer risk, such as
age, age at first menstrual period, family history of ovarian or
breast cancer, use of oral contraceptives, menopausal status, and
use of alcohol or tobacco.
Women's average height and weight in high-income countries has
steadily increased in past decades, the study authors noted in a
news release from the Public Library of Science.
The results of this large, observational study by the
Collaborative Group on Epidemiological Studies of Ovarian Cancer,
based at Oxford University in England, are published in this week's
issue of the journal
Although the researchers found an association between height and
weight and ovarian cancer risk, they did not prove that being
taller or heavier causes ovarian cancer.
