"...the study finds that women who ate the most carbs had twice the risk of breast cancer compared to women who ate the least amount."

Also, those feminists who burned their bras (hi Rosie) were onto something!
``In a study by Singer and Grismajer in 1995, 3 out of 4 women studied who wore a bra for 24 hours a day developed breast cancer compared to 1 out of 168 who wore a bra rarely or never.''
I am not sure if breast size was used as a confounding factor though, the article never mentioned that.

Mary M - Ohio - 07 Aug 2004 13:45 GMT I knew I'd see a post about this. The researcher interviewed on the Today show yesterday specifically talked about SUGAR being the possible culprit -- not healthy carbs. The interviewee also said that it shouldn't even be a headline story because it's so inconclusive -- they would have to do more careful testing of Mexican women, whom this "study" was done on. Again, the interviewee stressed that it was the amount of REFINED SUGAR that women with breast cancer in Mexico ate, not healthy carbohydrates.

Correct. In the study, the two highest associations to breast cancer were sucrose intake and obesity.
I was going to post the discussion section here, but when I went to the journal article, I did not have to enter my user name and password, indicating that the article is publicly available.

If you find you can't get into it, let me know and I'll repost here.
BTW, this is a better study than usual on this type of thing. Generally they're epidemiological studies, this one was actually a case control.

The P value for starch was 0.008, and P value for sucrose was 0.001, which means, in plain words, that starch consumption was strongly associated with breast cancer as well. The differences in P values for sucrose or starch are immaterial and the links are, practically speaking, just as statistically signIficant between starch and breast cancer as they are between sucrose and breast cancer.
It is hard to say what Mary meant by "healthy" carbs, since she did not elaborate, but starch is linked to breast cancer.
Note that correlation does not imply causation.
It is interesting that there was no statistically significant relationship between lactose and breast cancer.
Also, ``The associations between carbohydrate intake and breast cancer risk were similar in this subgroup compared with the total population and did not change appreciably when BMI was added to the model''. So weight does not explain breast cancer risk any better, when added to carb intake.
To those people afraid of fat, saturated or otherwise, ``total fat intake (substituted for a similar percentage of energy from carbohydrate) was not significantly associated with the risk of breast cancer. When we replaced total fat with specific types of fat, we observed that saturated and monounsaturated fat intakes were not associated with the risk for breast cancer (Table 4). In contrast, polyunsaturated fat intake was inversely related to the overall risk of breast cancer, particularly among postmenopausal women.''

The P value for starch was 0.008, and P value >for sucrose was 0.001, which means, in plain words, that starch >consumption was strongly associated with breast cancer as well. In table 3 (which evaluated carbohydrate consumption),:
Sucrose less than 5.2 percent had a CI of 1 risk, greater than 8.5 percent CI of 2
Fructose less than 4.3 percent CI of 1, greater than 10.1 percent CI of 1.36,
Lactose less than 3.02 percent CI of 1, greater than 8.4 percent CI of 1.06
Glucose less than 3.4 percent CI of 1, greater than 9.2 percent CI of 1..28
Starch less than 11.2 percent CI of 1.00 greater than 17.5 CI of 1.06.
So this means that increased consumption of sucrose doubled the chances of getting breast cancer in this population. Fructose raised it 36 percent, glucose 28 percent. Lactose and starch, very little difference.
The study that found the relationship between starch and breast cancer was a different study, referenced in the discussion section.
FWIW,

In 1843 it was discovered at The U of Paris Medical School that epidemological cancer rates mirrored per-capita grain consumption everywhere such data was available. The relationship between grain and cancer was thus 120 years more mathmatically obvious than that of cancer and tobacco.
The reason for this was only discovered in Sweden when in 2002 foods were tested for acrylamides. Levels in bread were found to exceed those considered a cancer risk by 300 times. One needs a OSHA permit to use pesticides with this level of carcinogens.
This makes a single slice of bread a far more likely source of cancer than a cigarette. It is also the first known discovery of a carcinogen that predicts epidemological cancer rates ( again). All other known causes of cancer are but mere statistical noise in comparison.
Acrylamides are also found in potato products, french fried potatoes being even worse than bread. PubMed ( available free to everyone due to public funding)is full of references to current research on this topic.
When can we expect warning label, such as found on cigarette packs, on such products? When can we expect full disclosure from Frito-Lay and other multi-nationals about the testing they're doing now on acrylamides?

High bone density increases risk of breast cancer Scott Gottlieb New York
Older women with high bone density are about twice as likely to develop breast cancer, a new study has found.
These results add to existing evidence that suggests that older women who have low bone mass have a decreased risk of breast cancer and, conversely, that higher bone density is associated with increased risk of breast cancer.
Bone mineral density can be an accurate marker of the body's response to oestrogen, in that women with higher bone density are thought to be physiologically more sensitive to the hormone's effects than women with lower bone density.
Because oestrogens have also been linked to risk of breast cancer, researchers in this study sought to determine if bone density might help also to predict the risk of breast cancer in older women.
The study, led by Dr Jane Cauley of the University of Pittsburgh Medical Center, followed the health history of 8905 women who were 65 years or older and without breast cancer.
After six years it found that the women who scored highest on three types of bone mineral density tests (performed on the bones of the wrist, arm, and heel) were also more likely to develop breast cancer (Journal of the National Cancer Institute 2001;93:930-936).
During the six year period a total of 315 women (3.5%) developed breast cancer.
After adjusting for other risk factors that contribute to breast cancer, such as age and obesity, the investigators found that the risk for women with the highest bone density for all three skeletal sites was 2.7 times greater than that for women with the lowest measurement of bone density for all three sites.
"The results suggest that bone mineral density is one of the most powerful predictors of breast cancer, especially advanced breast cancer, among elderly women," Dr Cauley said.
[ high bone density is an indicator of milk consumption - see any "Got Milk" ad] [The 2 studies quoted in the Harvard article gave a higher risk factor 3.5 to 4.5 times over the base line for breast cancer.]
Could bovine estrogens in milk affect the human immune system? Bovine insulin in milk has been implicated in Juvinile Diabetes- hmmmm.
