In November 2003, the American Cancer Society stated that breast cancer is the leading cause of death in women between the ages of 40 and 44. In the United States, there are approximately 200,000 new cases of breast cancer and more than 40,000 deaths; making the U.S. one of the countries with the highest death rate due to breast cancer. Perhaps the most alarming statistic is 1: 8 women will eventually develop breast cancer over their lifetime.

One of the most powerful steps a woman can take to reduce her risk for developing breast cancer is to educate herself about the petrochemicals, or xenoestrogens that are in her environment and work to eliminate or reduce them. Petrochemicals are “hormone disruptors” and it is through the unbalancing of your hormone system that can lead to problems. These xenoestrogens are found in cosmetics, lotions and fingernail polish and polish remover. They are obviously found in pesticides and insecticides. What you may not be aware of is that petrochemicals are found in plastics. If food is placed in a plastic container and reheated in the microwave, the plastic melts into your food and you ingest it. The harder the plastic, the more resistant it is to this process but the potential for accidental xenoestrogen ingestion is still present. Simply put, do not reheat food in plastic containers in the microwave.

Conventional screening methods all examine structure. For example, mammography uses X-ray to examine breast tissue. Any structure that has grown large enough to be seen by X-ray could be detected by mammography. However, mammography can have a high false positive rate. In fact, only 1 in 6 biopsies are found to be positive for cancer when found by mammography or clinical breast exam. This leads to increased psychological stress, physical trauma and financial concerns.

Other risks of mammography include the radiation exposure, although this has been debated by doctors for many years. Recently published in Radiation Research, 2004 the author suggests that the risks associated with mammography screening may be FIVE times higher than previously assumed and the risk-benefit relationship of mammography needs to be re-examined.

There exists a technology that can detect a breast issue YEARS before a tumor can be seen on X-ray or palpated during an exam. This technology has been approved by the FDA as an adjunctive screening tool since 1982 and offers NO RADIATION, NO COMPRESSION AND NO PAIN. For women who are refusing to have a mammogram or those who want clinical correlation for an existing problem, digital infrared thermal imaging may be of interest.

Thermal cameras detect heat emitted from the body and display it as a picture on a computer monitor. These images are unique to the person and remain stable over time. It is because of these characteristics that thermal imaging is a valuable and effective screening tool.

Breast thermography has undergone extensive research since the 1950s. There are over 800 peer-reviewed studies on breast thermography with more than 300,000 women included in large clinical trials. An abnormal thermogram is 10 times more significant as a future risk indicator for breast cancer than a first order family history of the disease. A persistently abnormal thermogram carries a 22-fold higher risk of future breast cancer.

Medical doctors who interpret the breast scans are board certified and endure an additional two years of training to qualify as a thermologist. Thermography is not limited by breast density and is ideal for women who have had cosmetic or reconstructive surgery. It is recommended that since cancer typically has a 15 year life span from onset to death, that women begin thermographic screenings at age 25.

Thermographic screening is not covered by most insurance companies but is surprisingly affordable for most people. For more information or to find a certified clinic in your area, go to www.proactivehealthonline.com.

We hear it all the time…lose weight for your health. Few people however, realize the extent to which this is critical to their physical well-being and ultimately their life expectancy.

In January 2003, the Journal of the American Medical Association featured a study finding that obesity appears to lessen life expectancy, especially among young adults. The researchers compared Body-Mass Index (BMI) to longevity and found a correlation between premature death and higher BMIs. For example, a 20-year-old white male, 5’10” weighing 288 pounds with a BMI of greater than 40 was estimated to lose 13 years of his life as a result of obesity.Jamie McManus, M.D., F.A.A.F.P. and author of “Your Personal Guide to Wellness” notes that while this study referenced extreme levels of obesity, there are still millions of overweight people in developed countries with a life expectancy rate that is three to five years less than their healthy-weight counterparts. She also estimates that there are 600,000 obesity related deaths each year in America.

Just how does obesity shorten our lifespan? The answer to this question is complex, yet there is a clear link between obesity and the development of cancer. An extensive study conducted by the American Cancer Institute involving 750,000 people showed that obesity significantly increased the risk of cancer developing in the following organs: breast, colon, ovaries, uterus, pancreas, kidneys and gallbladder.

Michael Thun, MD, vice-president of epidemiology and surveillance research for the American Cancer Society (ACS) says one reason obesity may raise cancer risk is because fat cells produce a form of estrogen called estradiol that promotes rapid division of cells, increasing chances of a random genetic error while cells are replicating, which can lead to cancer. In addition, fat centered around the abdomen may increase insulin and insulin-like growth factors in the blood, which may increase cancer risk.

"Women who are obese after menopause have a 50% higher relative risk of breast cancer," notes Thun, "and obese men have a 40% higher relative risk of colon cancer…. Gallbladder and endometrial cancer risks are five times higher for obese individuals”. There is evidence that cancer rates in developed countries are increasing at 5 to 15 times faster than developing countries. A major contributor to this alarming reality has proven to be diet. In populations where the diet consists mostly of fresh fruit and vegetables and whole grains – in contrast to the typical Western diet of fatty meats, refined flours, oils and sugars – the risk of cancer is much lower.

The interaction of diet and the development of cancer is an active field of research and Dr David Heber, M.D., Ph.D. and author of “What Color is Your Diet”, says “It appears that diet has its most significant effects after the cancer has already formed, acting to inhibit or stimulate the growth of that cancer”. At the risk of oversimplifying a complex set of interactions, the typical Western diet that leads to obesity may actually act to stimulate the growth of cancer cells. It is never too late to improve your health through healthful eating and adopting a more health-giving lifestyle. Here are simple steps to follow which can make an immediate improvement to your health and vitality.

1. Check your Body Mass Index (BMI) to determine if weight has become health risk. According to the Centers for Disease Control and Prevention, 60% of Americans are overweight, defined as having a BMI (a ratio of height to weight) over 25. Of those, nearly half (27%) qualify as obese, with a body mass index of 30 or more. In 1980, just 15% of Americans were considered obese. You can check your BMI at the website below.

2. Match your diet to your body’s requirements. If you eat and drink more calories than your body requires you will put on weight. Learn to control calories and portion sizes, make recipes leaner, and eat infrequently from fast food restaurants. Also learn how to snack with healthful choices.

3. Color your diet with a large variety of colorful, cancer-fighting fruit and vegetables. There are seven different color ranges of both fruit and vegetables and by choosing between 5 to 9 daily serves from a wide range of fruit and vegetables, we are extending our consumption of cancer (and other disease) fighting nutrients.

4. Eat lean protein with every meal. Protein provides a powerful signal to the brain providing a longer sense of fullness. The right source of protein is essential to controlling your hunger with fewer calories and necessary to maintain your lean muscle mass. Choices of protein should be flavored soy shakes with fruit; the white meat of chicken and turkey, seafood such as shrimps, prawns scallops and lobster and ocean fish or vegetarians may prefer soy based meat substitutes.

5. Rev up your metabolism with activity. If you want to enjoy a lifetime of well-being, exercise is a key ingredient. Colleen Doyle, MS, RD, director of nutrition and physical activity for the American Cancer Society (ACS), says adults should do something for 30 minutes each day that takes as much effort as a brisk walk. Children should be active for an hour each day. We are more likely to develop habits around things we enjoy, so seek activities which you enjoy doing. It is also helpful to build physical activity into your daily routine: use the stairs instead of the escalator or lift at work, park your car in the parking bay furthest from the super marketing and don’t use the remote control to change TV channels.

6. Get support to ensure you develop a healthful eating plan and reach your goal weight. Whilst a small percentage of people possess the discipline to lose weight, many obese people have developed strong thoughts and habits concerning the food they eat. In order to establish new habits, most people respond well to some form of consistent encouragement and coaching. A study, “Effects of Internet Behavioral Counseling on Weight Loss in Adults at Risk of Type 2 Diabetes” shows that participants who had the support of weight loss coaching lost more weight than those who didn’t. The study concluded that the support of a weight loss coach can significantly improve weight loss results.

Being overweight or obese has been identified next to smoking, as the most preventable major risk to developing cancer. Even small weight losses have been shown to have beneficial health effects. So it’s never to late to start and you can never be too young or too old to be concerned about your health and do something about achieving a more healthy weight.

Janet M., a fifties-something woman, entered my office and said as she sat down, "I've read that if I take hormones I'll increase my breast cancer risk. I'm going crazy without sleep and with these mood swings, but I don't want to increase my breast cancer risk by taking hormones."

Like many women, Janet had heard that a recent study, the Women's Health Initiative (WHI), definitively showed that hormone replacement therapy (HRT) increases breast cancer risk. Janet, like most people, didn't realize that this study found no statistically significant increase in breast cancer risk to women who took HRT.

When differences are not significant, an increase in risk may well be due to other factors, not the one being studied, such as HRT use. As often happens when a medical story is reported, the emphasis was on the increase in risk, not whether the increase was likely to be due to the agent being studied or to the size of the risk.

The actual size of a risk is important in any woman's decision making process. In this case the risk was exceedingly small -- only 8 in 10,000 women a year -- which is 0.08% or eight hundredths of one percent! Janet was amazed to learn the actual size of the increase, and said, "You mean I was getting all concerned for a risk that small!"

"And," I pointed out, "even this very small difference in risk may not be due to hormone use." I explained that breast cancers take an average of eight years to reach about half an inch in size. This means that breast cancers started in the first year of the study would not be detected for eight or more years. The study followed women for only about five years, so all or most of the breast cancers found were probably present in an undetected state before the study began.

Janet asked if HRT use might have caused some breast cancers to grow more rapidly and therefore be detected sooner than eight years. This is unlikely. A number of studies find that breast cancers in women who were using HRT were not larger and were not dividing more rapidly than breast cancers in non hormone users. Since breast cancers grow more slowly in older women and the average age in this study was 63, breast cancers in this group would tend to grow more slowly and so take even longer than the eight year average to be detected.

Women in the WHI study used a particular type of hormone Prempro. The results of this study therefore do not apply to other, newer approaches in which more natural hormones are used and a woman's menstrual cycle is more closely approximated.

Janet was surprised to learn that many studies find that women who use HRT do not have an increase in breast cancer risk compared to women who don't use hormones, even when hormones are used for twenty years. Also, in another large study in which some women were assigned to take Prempro and others not, women who used Prempro had no significant increase in breast cancer risk.

As Janet left, she said, "I can see now that when I hear about a study I need to know how big a risk is and not just that it is increased. I'll also ask how long a study it was. This discussion has given me a whole different perspective."

Most women are familiar with mammography as our "gold standard" for breast cancer screening. However, there are additional tools available that women can add to their arsenal.

One of the most effective tools in breast cancer screening is breast self-exam (BSE). However, BSE works best when women are appropriately trained in the procedure, and then followed-up with annual clinical breast exams (CBE) from their physicians. In a 2000 University of Toronto study, approximately 20,000 women were screened for breast cancer with BSE and annual CBE, and 20,000 were screened with BSE and mammograms. After more than 10 years, the BSE and annual CBE reported 610 cases of invasive breast cancer, and 105 deaths. In the BSE and mammogram group, there were 622 cases of invasive breast cancer and 107 deaths. Without question, the first line of defense against breast cancer begins with diligent BSE.

Other tools that are available to women include the AMAS (anti-malignan antibody screen) test and the NMP Nuclear matrix protein) test. Both these are blood tests that measure a certain protein in the blood that may indicate cancer. The AMAS test has been around for several years while the NMP test has not been available until only recently. Clinical trials continue in this area.

One additional tool that may detect an issue early is digital infrared thermal imaging or DITI. In 1982, the FDA approved thermography as an adjunctive tool for breast cancer screening. DITI measures heat emitted from the body and is accurate to 1/100th of a degree. DITI examines physiology, NOT structure. It is in this capacity that DITI can monitor breast HEALTH over time and alert a patient or physician to a developing problem; possibly before a lump can be seen on X-ray or palpated clinically. There are no test limitations such as breast density. DITI is a non-invasive test that does not emit radiation.

The unique characteristics of cancer allow DITI to detect breast cancer at an earlier stage of growth. As cancer is developing, it builds its own blood supply which is then reflected as increased heat in that particular region of the breast. DITI has a specificity of 83%; which reflects a problem in its early stages of development not late-stage cancer as in mammography. An abnormal thermogram carries a 10-times greater risk for cancer and a persistently abnormal thermogram carries a 22-times greater risk for cancer.

Clinical research studies continue to support thermography’s role as an adjunctive tool in breast cancer screening and the ONLY tool that measures breast health over time. There are now more than 800 publications on over 300,000 women in clinical trials. A recent finding published in the American Journal of Radiology in 2003 showed that thermography has 99% sensitivity in identifying breast cancer with single examinations and limited views. Scientists concluded that a negative thermogram is powerful evidence that cancer is not present.

Thermographic screening is not covered by most insurance companies but is surprisingly affordable for most people. For more information or to find a certified clinic in your area, go to www.proactivehealthonline.com.
