October is National Breast Cancer Awareness Month; a pink ribbon symbolizes
the cause.
FACT
Japanese women are one-quarter as likely to die of breast cancer as
American women. Probable reasons: They eat less fat and meat, but more
fish, fruits, vegetables and soybean foods. Breast cancer rates rise dramatically
among Japanese women who move here and adopt Western diets.
Fiction
Contrary to popular belief, caffeine does not promote breast cancer,
says the National Cancer Institute.
The U.S. death toll
Breast cancer is the No. 1 cause of death for women 35 to 54.
46,000 women will die from breast cancer this year, reports the American
Cancer Society.
6 foods that may help
--Cruciferous veggies. Cabbage, broccoli, cauliflower and Brussels
sprouts are rich in a chemical, indole-3-carbinol, that helps to rid the
body of cancer-promoting estrogen, show tests by H. Leon Bradlow at Strang
Cornell Cancer Research Laboratory. Eating such vegetables should cut
breast cancer odds, its recurrence and metastasis (spread). In tests,
an effective dosage equaled eating one-quarter of a head of cabbage a
day. Raw is best; light cooking is OK; heavy cooking destroys indoles.
Lower estrogen benefits start to kick in within a week.
--Soy proteins. Soybeans, including tofu, soy flour, soy milk
and soy nuts, contain several anti-cancer chemicals. Kenneth Setchell
at Children's Hospital Medical Center in Cincinnati found that giving
premenopausal women 2 ounces of soy protein daily induced signs of breast
cancer protection (rises in some hormones, drops in others, longer menstrual
period). In animals, soy protein has blocked 65 percent of breast cancers.
Note: Soybean oil and soy sauce have insignificant anti-cancer activity.
--Wheat bran. Eating wheat bran can reduce cancer-promoting estrogen,
reports David P. Rose at the American Health Foundation. In his landmark
study, estrogen levels sank 17 percent in two months in women eating three
to four high-fiber wheat bran muffins a day (bringing daily fiber intake
to 30 grams total). Note: Oat and corn bran muffins did not work. Wheat
bran ties up estrogen in the intestinal tract, causing much to be excreted.
Rose expects the same benefits from 1/2 cup cereal such as All-Bran or
6 tablespoons of raw, unprocessed wheat bran daily. Animals that are fed
a low-fat, high-fiber diet have half as many expected breast tumors.
--Fish. Much research suggests that omega-3 fat in fish fights
breast cancer. Rose also found that fish oil dramatically squelched the
spread of human breast cancer cells injected into mice. Studies are in
progress at Harvard to determine if fish oil treatments reduce the spread
of breast cancer after surgery. Rutgers University researcher Rashida
Karmali reported that modest supplements of fish oil suppressed signs
of developing breast cancer in women at high risk.
--Fruits and vegetables. About 150 studies show that eating lots
of fruits and vegetables cuts in half the odds of most cancers, including
breast cancer. One reason: their plentiful antioxidants, such as vitamin
C. National Cancer Institute of Canada researchers found that eating too
little vitamin C (under 380 milligrams a day) raised breast cancer odds
as much as eating a high-fat diet. An Italian study found women who ate
more than one green vegetable daily had one-third the risk of women who
ate less.
--Olive oil. It may help prevent breast cancer, according to
much research, including two recent Harvard reports. Women in Greece who
ate olive oil more than once a day had a 25 percent lower risk of breast
cancer than women who ate it once a day. Eating more than 2 teaspoons
daily cut breast cancer risk in Spanish women by 35 percent. In animals,
olive oil discourages breast cancer growth; corn oil encourages it. Substitute
olive oil for other fats.
3 suspected villains
--Fat. Much research suggests a fatty diet promotes breast cancer,
although evidence is controversial and studies are ongoing. Beware especially
of omega-6 vegetable oils (corn, safflower and sunflower seed oil, including
margarine and mayonnaise), meat, poultry and dairy fats.
--Meat. Researchers at New York University Medical Center recently
tracked 14,291 women for six years. Women who ate meat daily (beef, veal,
lamb, pork, luncheon meats) were about twice as likely to develop breast
cancer as women eating mostly fish and
--Alcohol. The extent of the hazard is unclear. A new study of
16,000 women by UCLA researcher Matthew P. Long-necker found the risk
of breast cancer went up 39 percent with one beer or standard mixed drink
daily, 69 percent with two drinks and 230 percent with three drinks a
day. Wine was not linked to greater risk of breast cancer in this study,
though it has been in others. Other research suggests little or no danger
from one serving of alcohol a day or less.
