Teatime May Help Prevent Ovarian Cancer
There aren't many steps a woman can take to reduce ovarian cancer risk with makes this latest research all the more exciting
Other than pregnancy and regular use of birth control pills, there aren't many steps a woman can take to reduce ovarian cancer risk. This makes this latest research, which points to the protective effects in the simple habit of drinking tea, all the more exciting.
Tapping into tea
To better understand how tea may affect ovarian cancer risk, researchers compared green, black, and herbal tea drinking habits of 1,368 women with and 1,416 women without ovarian cancer. The women were similar to one another in terms of age and area of residence.
Women who drank four or more cups of any type of tea per day were 29% less likely to be diagnosed with ovarian cancer compared with women who reported drinking no tea. When considered individually, each type of tea--green, black, and herbal--appeared to protect against ovarian cancer, although none of these results were statistically significant.
Beware of bias
This type of research, which is called a case-control study, should be considered with these limitations in mind: Women with ovarian cancer may remember their dietary habits differently than women without the disease. In addition, there may be other differences between women who do and do not drink tea, and those differences might influence ovarian cancer risk. The researchers did not account for all of these possible differences between the two groups of women, which can lead to bias and inaccurate results.
For comparison, the study authors also reviewed other existing research on tea and ovarian cancer. They found overall, the studies tend to agree that tea drinking may lower ovarian cancer risk. This consistency between different studies suggests a potential protection benefit of tea.
