|Botanical|| Green / Oolong / BlackTea (Camellia sinensis)
| ||Drinking tea can cut the risk of developing ovarian cancer by almost half, according to a major study by scientists in Sweden. Just two cups of tea a day was found to reduce the chance of the disease by 46%, the researchers found, after studying the records of more than 61,000 women over a period of about 15 years.|
Laboratory research has found that black and green tea can protect against a range of cancers, but there have been few studies to look at the real incidence of cancers among drinkers and non-drinkers of the brew, until now. [Archives of Internal Medicine, Dec. 12, 2005]
| ||The intake of vegetable fiber, but not of fruit or cereal fiber, was found to be negatively associated with risk of ovarian cancer, with a 37% decrease in the odds for each 10gm per day addition. [Am J Epidemiol 139(11): S37, 1994]|
Consumption of foods containing beta-carotene by 71 women with epithelial cancer of the ovary and 141 matched controls was investigated. Consumption of carrots was found to decrease risk. [Nutr Cancer 15: pp.239-47, 1991]
Fried Foods Avoidance
| ||16,000 Seventh Day Adventist women who consumed eggs at least 3 times weekly, had a 3 times greater risk of fatal ovarian cancer than did women who ate eggs less than once weekly. Fish, chicken and potatoes were also positively associated with fatal ovarian cancer when they were fried. Consumption of fried eggs showed the strongest association with fatal ovarian cancer, perhaps due to interference with cholesterol biosynthesis and consequently the manufacture of ovarian hormones from the production of cytotoxic oxidation products of cholesterol. [ JAMA 254(3): pp.356-7, 1985]|
Increased Fish Consumption
| ||Study subjects who ate two or more servings of fish weekly had a much lower risk for esophageal, stomach, colon, rectum, and pancreatic cancers than those who avoided fish. In fact, the rates of these types of cancer were 30 to 50 percent lower among fish eaters. High fish consumption was also associated with lower risks for cancers of the larynx (30 percent lower risk), endometrial cancer (20 percent lower risk), and ovarian cancer (30 percent lower risk).|
Animal/Saturated Fats Avoidance
| ||630 women aged 35-79 with ovarian cancer were studied. Increasing saturated fat consumption was associated with an increasing risk of ovarian cancer. No relationship was seen with the intake of unsaturated fats. [J Natl Cancer Inst 86( 18): pp.1409-15, 1994]|
450 histologically confirmed new primary epithelial ovarian cancer cases aged 35-79 were compared to 564 randomly selected population controls. Cholesterol from eggs was related to increased risk. [Am J Epidemiol 139(11): S37, 1994]
| ||Studies linking coffee consumption with cancer are conflicting and inconclusive at this point, but there is a suggestion of a higher incidence of cancers of the pancreas, ovaries, bladder, and kidneys in coffee drinkers.|
| ||There is research indicating a potential link between the use of genital talcum powder and ovarian cancer. Thus, the use of talcum powder between the legs is not recommended.|
Diindolylmethane DIM / Indole 3 Carbinol IC3
| ||We all know that eating fruits, vegetables and soy products provides essential nutrition for a healthy lifestyle, while obesity leads to the opposite. Yet proving the effect of nutrition, or obesity, on cancer is an experimental challenge and a focus for scientists. According to emerging evidence being presented at the 2007 Annual Meeting of the American Association for Cancer Research, eating well might still be one of the more pleasurable ways to prevent cancer and promote good health.|
Eating such foods as broccoli and soy are believed to offer some protection against cancer, but how this occurs is not well-understood. Now, in laboratory experiments, researchers at the University of California, Los Angeles, have discovered a biological mechanism whereby two compounds in these foods might lower the invasive and metastatic potential of breast and ovarian cancer cells.
They found that diindolylmethane (DIM), a compound resulting from digestion of cruciferous vegetables, and genistein, a major isoflavone in soy, reduce production of two proteins whose chemotactic attraction to each other is necessary for the spread of breast and ovarian cancers.
When applying purified versions of DIM (diindolylmethane) and genistein to motile cancer cells, the researchers could literally watch these cells come to a near halt. When either compound was applied, migration and invasion were substantially reduced.
"We think these compounds might slow or prevent the metastasis of breast and ovarian cancer, which would greatly increase the effectiveness of current treatments," said Erin Hsu, a graduate student in molecular toxicology. "But we need to test that notion in animals before we can be more definitive."
Both diindolylmethane and genistein are already being developed for use as a preventive and a chemotherapy treatment for breast cancer, although more extensive toxicological studies are necessary, the researchers say.
Sunlight / Light Exposure
| ||Vitamin D metabolite receptors are found on endocrine and reproductive organs and are known to play a role in inhibiting a number of cancer cell lines. The incidence of ovarian cancer varies with latitude, with higher rates in northern parts of the world. In this study, the quantity of sunlight was strongly inversely correlated with the incidence of death due to ovarian cancer in 100 of the largest US cities (1979-88) after adjustments were made for air pollution levels. Northern women in the 5th decade of life were found to have 5 times the mortality rate from ovarian cancer as southern women. [Epidemiol 23 (6): pp.1133-36, 1994]|
| ||Researchers studied more than 2,100 women and found that those who exercised for more than 6 hours per week were 27% less likely to develop ovarian cancer than women who exercised less than 1 hour each week. High activity levels were found to protect women of all ages. [Obstetrics and Gynecology 96: pp.609-14, October 2000]|
Test for Ovarian Cancer
Test / Monitor Hormone levels
| ||Testing for estrogens and progesterone may help to properly evaluate breast and ovarian cancer risk as some estrogens will promote risk while progesterone may protect against this cancer risk.|
Test AMAS (AntiMalignin Antibody Screen)
| ||20,305 American women were followed prospectively for 20 years. Initial serum selenium levels were inversely related to the risk of ovarian cancer. [J Natl Cancer Inst 88(1): pp.32-7, 1996]|| |
