(October 16, 2026) Aware of it but no action on it To promote breast cancer awareness, prevention, and research in October, the American Cancer Society recently released the findings of its new survey, pointing out that significant gaps exist between awareness of modifiable breast cancer risk factors and taking positive action to lower risk.   After decades of campaigning breast cancer awareness in October, it is exciting that the survey found 99% of 32,775 survey respondents know that smoking raises cancer risk. 91% of them learn low physical activity levels raise risk. 89% of women know excess body weight increases risk. 85% of ladies know alcohol use is also going to raise risk.   The survey also looked into awareness of breast cancer risk and protective factors by race and ethnicity. Among Asian Americans, Native Hawaiians, and Pacific Islanders (AANHPI), 99% of women in this group know that smoking raises cancer risk. 92% of them learn low physical activity levels raise risk. 89% of them know excess body weight increases risk. The percentage of AANHPI women knowing alcohol use could raise risk is also 89%.   It is great to learn that the awareness levels of breast cancer risk factors among AANHPI ladies are as high as overall survey respondents.   However, while 91% of women surveyed know that low levels of physical activity increase cancer risk, only 27% of the same respondents meet the American Cancer Society’s recommendation of 150 to 300 minutes of moderate-intensity activity, or 75 to 150 minutes of vigorous-intensity activity, each week.   Alcohol use shows the second-widest gap in the survey, with 85% of women knowing alcohol raises cancer risk and 69% still report drinking to some extent.   In addition, 89% of women know excess body weight increases cancer risk, but only 47% meet the American Cancer Society’s recommendation of staying at a healthy body weight throughout your life. And, 99% of ladies know smoking raises risk, but 28% of them do not avoid smoking or quit.   The research of the survey did not further investigate the awareness-action gaps of each ethnicity group. Given that Guam’s adult obesity prevalence was getting higher in recent years, it is reasonable to infer that quite a number of people in our island community did not take action to really balance their food intake and physical activity even though the awareness of risk factors may be high.   When the U.S. Centers for Disease Control and Prevention (CDC) released 2023 Adult Obesity Prevalence Maps for 48 states, the District of Columbia, and 3 territories in September 2024, Guam’s adult obesity rate was above 35% for the first time. On the CDC’s 2024 maps released in December 2025, Guam’s adult obesity rate increased again and was surprisingly jumping to 40.2%. There were only 3 states or territories with 40% or higher adult obesity rates.   However, in addition to diet and exercise, body weight is affected by many other factors, including genetics, hormones, environment, medications, and stress. An individual’s willpower alone does not drive weight-loss outcomes. A supportive ecosystem is crucial and necessary.   So, our foundation wants to point out that the American Cancer Society actually emphasized their survey results highlight the importance of initiatives to expand access to “safe, walkable community” and “affordable, healthy food” to help people easily take action in their daily life to increase physical activity and eat healthy.   Regarding “safe, walkable community,” it means people are able to safely and comfortably walk around their neighborhood, instead of driving to certain places and then walking or running there. Obviously, the system on our island has to allocate lots of resources to improve certain infrastructure to reach this goal. In addition, at the same time, the issues of stray dogs must be addressed. Otherwise, many people will not feel safe walking around their village.   Our island community also needs to work harder to secure the stability of the shipment of fresh food from off-island as well as the supply of the locally produced food, helping people's access to “affordable, healthy food.” That is why our foundation appreciates the hard work of the Port Authority of Guam, the shipping companies, and all related parties. We also admire the continuous efforts made by many local farmers, experts, and organizations that try to strengthen our island’s food resiliency.   The American Cancer Society also mentioned in its report that the findings of the survey have implications for public health awareness efforts as well as conversations between healthcare providers and their patients.   For example, breastfeeding for women who have children and can breastfeed is the least-known protective factor in the survey. Only 55% of women know that breastfeeding for several months after childbirth may offer the added benefit of reducing breast cancer risk. Its awareness level is much lower than other factors’. The percentage of AANHPI women knowing this protective factor is also just 57%. Some improvement could be made through public health awareness efforts or conversations between healthcare providers and their patients.   It is also important that people pursuing a healthy body weight can learn the science behind weight management from professionals. Our foundation looks forward to more relevant conversations between healthcare providers and their patients to facilitate the learning and motivate patients to take action on obesity or other health issues.   Finally, we would like to stress once again that steady lifestyle changes are helping long-term well-being. Once you make a start, even small improvements can bring meaningful benefits. So, regarding prevention, please do take action to make some changes after you are aware of the risk factors. Let’s close the awareness-action gaps.

Links：http://nccam.nih.gov/health/providers/digest/diabetes-scienc ...

The National Center for Complementary and Alternative Medicine (NCCAM) at NIH (National Institute of Health) recently published information about if dietary supplements help control type 2 diabetes. Overall, they concluded there is not enough scientific evidence to show that any dietary supplement can help manage or prevent type 2 diabetes.

 

Minerals

 

Magnesium is essential to the body’s ability to process glucose. Magnesium deficiency has been associated with diabetes. A large 2007 clinical trial, found an association between a higher intake of cereal fiber and magnesium and a reduced risk of developing type 2 diabetes.

 

If you have too little chromium in your diet, your body can’t use glucose efficiently. However, studies, including a 2007 systematic review, have found few or no benefits of chromium supplements for controlling diabetes or reducing the risk of developing it. In addition, Chromium supplements may cause stomach pain and bloating.

 

Herbs

 

A 2012 systematic review of 10 randomized controlled trials did not support using cinnamon for type 1 or type 2 diabetes. In addition, When researchers tested samples of the common spice cassia cinnamon for sale at grocery stores in Europe, they found many samples contained coumarin, a substance that may cause or worsen liver disease in people who are sensitive.

 

A few studies have examined the herbs Asian ginseng and American ginseng and their effects on controlling glucose levels. Currently, research reviews and clinical trials show that there is not enough evidence to support the use of the herbs Asian ginseng and American ginseng for diabetes.

 

NCCAM emphasized that interactions between herbs and conventional diabetes drugs have not been well studied and could be a health risk.

 

Other Supplements

 

Alpha-lipoic acid and vitamin E supplements taken separately or in combination did not improve cholesterol levels or the body’s response to insulin in a 2011 clinical trial of 102 people with type 2 diabetes.

 

A 2011 clinical trial of 467 participants with type 2 diabetes found that 600 milligrams of alpha-lipoic acid daily did not prevent diabetic macular edema, an eye condition that causes blurred vision. High doses of alpha-lipoic acid can cause nausea, upset stomach, fatigue, and insomnia.

 

A 2012 study that combined a meta-analysis and a systematic review looked at the possible link between eating seafood or plants with omega-3s and the risk of developing type 2 diabetes.  The study found little evidence that these dietary sources of omega-3s affected the risk of developing diabetes.

 

Omega-3 supplements may extend bleeding time. Besides, Omega-3 supplements usually do not have negative side effects. When side effects do occur, they typically consist of minor gastrointestinal symptoms, such as belching, indigestion, or diarrhea.

 

The evidence is still preliminary on the effects on diabetes of polyphenols—antioxidants found in plant-based foods such as fruits, grains, and vegetables.
