OBJECTIVE: Hyperinsulinemia may promote mammary
carcinogenesis. Insulin resistance has been linked to an increased risk of
breast cancer and is also characteristic of type 2 diabetes. We prospectively
evaluated the association between type 2 diabetes and invasive breast cancer
incidence in the Nurses' Health Study. RESEARCH DESIGN AND METHODS: A total of
116,488 female nurses who were 30-55 years old and free of cancer in 1976 were
followed through 1996 for the occurrence of type 2 diabetes and through 1998
for incident invasive breast cancer, verified by medical records and pathology
reports. RESULTS: During 2.3 million person-years of follow-up, we identified
6,220 women with type 2 diabetes and 5,189 incident cases of invasive breast
cancer. Women with type 2 diabetes had a modestly elevated incidence of breast
cancer (hazard ratio [HR] = 1.17; 95% CI 1.01-1.35) compared with women without
diabetes, independent of age, obesity, family history of breast cancer, history
of benign breast disease, reproductive factors, physical activity, and alcohol
consumption. This association was apparent among postmenopausal women (1.16;
0.98-1.62) but not premenopausal women (0.83; 0.48-1.42). The association was
predominant among women with estrogen
receptor-positive breast cancer (1.22; 1.01-1.47). CONCLUSIONS: Women with type
2 diabetes may have a slightly increased risk of breast cancer.

American
Cancer Society Now Believes Obesity is as Dangerous as Smoking
The risk of cancer from
being obese is similar to the risk of cancer from using tobacco, according to
the American Cancer Society, and experts suggest that obesity may soon surpass
smoking as the leading cause of preventable deaths.
Being overweight or obese
is associated with a higher risk of several types of cancer, including colon
and breast cancer, and evidence suggests that being physically active can
reduce cancer risks, especially for colon and breast cancer.
One-third of cancer deaths
are related to diet and inactivity, and experts believe that about 186,000
lives could be saved each year if people made lifestyle changes.
To spur such changes, the
society will launch the Great American Weigh In, similar to the Great American Smokeout, which began about three decades ago and
encouraged people to quit smoking.
The Weigh In aims to
establish a link between fat and cancer in the minds of the public, as a recent
survey found that only one percent of participants knew that maintaining a
healthy weight would also keep cancer risk down.
The program asks people to
gauge whether they are overweight or obese by measuring their body mass index
(BMI), a measurement of obesity involving height and weight.
Women will be a primary
target for the society since they typically make decisions on what to feed the
family and are also more likely than men to make lifestyle changes. The link
between weight and breast cancer, which is the most feared disease among women,
will also be a major motivator for women to maintain healthy weights, according
to the society.
The Weigh In’s simplistic goal, measuring BMI, may trigger people to
take other healthy steps. However, the program’s simple goal has been
criticized by some who say a next step, such as a 30-minute walk each day, should
be suggested. Other strategies include using law, as is the case with smoking
(for example people cannot smoke inside many buildings). One suggestion for
food would be to reduce prices of healthier food and raise taxes on higher fat
ones.

Obesity Causes Nearly 100,000 Cancer Deaths per Year |

Excess body weight and obesity may play a role in a significant number of cancer deaths, according to a report from the American Cancer Society. Results from the study, which involved close to 1 million people, indicated that 14 percent of cancer deaths in men and 20 percent of cancer deaths in women might be due to being overweight or obese. Further, if Americans maintained healthy weights, more than 90,000 cancer deaths could be avoided each year, according to researchers. Researchers followed more than 900,000 Those who were overweight or obese had a higher risk of death from various cancers, including esophagus, colon and rectum, liver, gallbladder, pancreas, kidney, non-Hodgkin’s lymphoma and multiple myeloma, as compared to people of normal weight. The higher the BMI, the greater the risk of cancer, researchers reported. Among the heaviest participants, the risk of death from cancer was 52 percent higher in men and 62 percent higher in women compared to people of normal weight. The heaviest men were more likely to die from stomach or prostate cancer, while cancer of the breast, uterus, cervix or ovary was most likely to cause death among the heaviest women. Researchers were uncertain exactly why obesity might increase risk of death from cancer but suggest that the higher levels of hormones common in people with higher BMIs may predispose them to cancer. Additionally, excess weight in the abdomen may disrupt the metabolism of insulin, which can increase the risk of cancer, and people with obesity may be more likely to develop gallstones and reflux disease, which can lead to chronic inflammation and certain cancers. Researchers note that, for people who are overweight or obese, losing any amount of weight could be useful in reducing risk of death from cancer. The New England Journal of Medicine |

ABSTRACT
Background The influence of excess body weight
on the risk of death from cancer has not been fully characterized.
Methods In a prospectively studied
population of more than 900,000
Results The heaviest members of
this cohort (those with a body-mass index [the weight in kilograms
divided by the square of the height in meters] of at least 40) had
death rates from all cancers combined that were 52 percent higher
(for men) and 62 percent higher (for women) than the rates in men
and women of normal weight. For men, the relative risk of death
was 1.52 (95 percent confidence interval, 1.13 to 2.05); for women,
the relative risk was 1.62 (95 percent confidence interval, 1.40 to
1.87). In both men and women, body-mass index was also significantly
associated with higher rates of death due to cancer of the esophagus, colon and rectum, liver,
gallbladder, pancreas, and kidney; the same was true for death due
to non-Hodgkin's lymphoma and multiple myeloma. Significant trends
of increasing risk with higher body-mass-index values were observed for
death from cancers of the stomach and prostate in men and for death
from cancers of the breast, uterus, cervix, and ovary in women.
On the basis of associations observed in this study, we estimate
that current patterns of overweight and obesity in the
Conclusions Increased body weight was
associated with increased death rates for all cancers combined and
for cancers at multiple specific sites.
