Are we living in a toxic environment? The experts at Canyon Ranch ask us to consider these facts:

• The EPA estimates that 4.7 billion pounds of toxic chemicals are released into the environment annually.
• It's likely that 25 percent of the U.S. population suffers from some level of heavy metal poisoning.
• Fourteen pounds of food colorings, additives, preservatives, emulsifiers, and flavorings are consumed per person each year.

Toxic? Maybe. At minimum, though, we are living in a world filled with chemicals, pesticides, additives, preservatives, antibiotic and hormone residues, and heavy metals. Whether consumed, inhaled, or absorbed, our bodies soak this stuff up. In order to reduce the load, and the toll it takes it takes on our health, there's something we can do. We can eat clean. Here's how:

Yesterday I visited the High Points Monument at High Point State Park. It was a fitting day to visit the monument -- Memorial Day. The monument was built and dedicated to the memory of New Jersey's wartime heros. Construction was started in 1928 and completed in 1930.

My husband and I climbed the stairs up the 220- foot structure for a breathtaking view of the ridges of the Pocono Mountains, the Catskill Mountains and the Wallkill River Valley.

The high points in my life can come unexpectedly. I think we should all think about what the high points in our lives have been and cherish the memories. A camping trip in an RV, my husband and two dogs this weekend was definitely a high point in my life. High points don't have to be something monumental -- no pun intended. High points can be small things that make the day a joyful one.

Find as many high points in your life as you can.

It's scary but true: Chemicals are all around us, in the air we breath, the things we eat and drink and even our homes. According to this article, alarming levels of harmful chemicals are being found in the bodies of average Canadians of all ages ... from newborns to the elderly. We don't think about these kinds of statistics -- and we don't want to -- but we're going to have to if we want to be the healthiest we can.

The Canadian group Prevent Cancer Now has made it their mission to help reduce the amount of harmful substances, some of them carcinogens, that are lurking in our environment. They're striving to make changes in all levels of the Canadian population -- from the individual right up to the government and big corporations.

It's about time! What do you think?

As was pointed out on Heather Craven's May 17th post, it is essential to protect children early on from sun exposure. I think it is worth repeating, because it is such an important precaution. During my research for Skin Cancer Awareness month, I came across a statistic that really made me think. The risk of some cancers can be reduced by 78% if skin is adequately protected during the first 18 years. One of the questions routinely asked in questionnaires to assess your skin cancer risk is: "Did you have one or more severe, blistering sunburns as a child or teenager?"

Think about this:

If we protect our children's skin now, we are giving them the gift of health for the rest of their lives.

I am sure that it is very hard to convince a child who feels hot to wear a long-sleeved shirt or to stand still to have some sun lotion smeared all over them. When we consider, though, that even one severe sunburn can double the risk of skin cancer, it should be more than worth it. Parents will do anything to protect their children from harm and this is one more thing that we can add to the list. I am not advocating that we keep the poor darlings inside all the time, but that we are aware of the dangers. How would you do it? Do parents out there think that it is worth the effort?

Antiretroviral drugs, used to prevent HIV transmission from mother to child, are now believed to cause genetic damage in infants. This damage, leading to an increased risk of developing cancer, makes it highly plausible these children may be diagnosed with the disease in mid and late adulthood.

Two new studies indicate there are cancer-causing effects of transplacental exposure to AZT, an antiretroviral drug. These effects -- like increased incidence of tumors and tumors with genetic changes -- have been demonstrated in mice and rats and seem to be cause for concern in humans too.

"The cumulative mutagenesis data suggest that infants exposed transplacentally to AZT may be at increased risk for cancer as they age," said one researcher, whose findings are published in Environment and Molecular Mutagenesis.

Breast cancer survivor and Grammy- winning rock star Sheryl Crow was on Capital Hill last week where she urged Congress to pass a bill that would provide funds for research into the possible connection between breast cancer and the environment.

The Breast Cancer and Environmental Research Act -- predicted to pass, by the way -- would allocate $40 million for study into an area not receiving much attention.

"We're looking into all these different scientific methods, with gene therapy with stem cells, it's all very encouraging but we have not tapped into the area of the environment," Crow says. "We have to look at the environment, we cannot ignore it anymore."

This same bill was defeated last year in the Senate but Senator Harry Reid (D-Nevada) says that was then, this is now.

"We're going to complete this legislation in the Senate this year," he said.

Discoveries have linked certain viruses to cancer growth. The hepatitis B virus is related to liver cancer. Women who develop cervical cancer have had a human papilloma virus (HPV) infection but not all women with HPV infection will develop cervical cancer. Stomach ulcers are likely caused by Helicobactor pylori, or H. pylori a bacteria and the ulcers can grow into cancer. Viruses attack cells in the body and once these cells are corrupted they begin to grow uncontrollably, eventually leading to cancer.

With these discoveries leads us to the knowledge that protecting the immune system in the body and keeping viruses at bay, is important in preventing cancer. Viruses enter the body through everyday activities like eating, breathing and sexual activity. Eating well, exercising and avoiding alcohol and cigarettes are good ways to keep your body's natural defenses functioning at their best. Staying protected with condoms during sexual intercourse helps protect you from sexually transmitted viruses and diseases. Learning healthy life style habits is the beginning of keeping cancer at bay. Focusing on nutrition, exercise, body weight, keeping toxins out of our bodies and our home environment ,and lowering stress will all help boost the immune system.

I guess the concept is happy -- the public urging for our world's policy makers to make cancer a top priority -- but the fact that becomes all too apparent on this World Cancer Day is quite sobering. More than seven million people die from cancer and close to 11 million new cases are diagnosed worldwide each year. In 2006, cancer killed more people than AIDS, malaria, and tuberculosis combined.

So today is both happy and sad. But for now, let's focus on the happy.

The Geneva-based International Union Against Cancer (UICC) and member organizations in 86 countries are launching a five-year campaign to impart life lessons to children so they can prevent cancer later in life. Parents are critical in this campaign and must take an active role in teaching their children techniques for saving their lives.

Forty-three percent of cancer cases can be prevented through healthy lifestyles that begin in childhood. The World Cancer Campaign slogan -- Today's Children, Tomorrow's World -- underscores the possibility that a concerted effort among world leaders, parents, and their children can make a real difference through four key actions -- providing a smoke-free environment for children; ensuring children keep physically active, eat a healthy diet, and avoid obesity; educating children about vaccines for virus-related liver and cervical cancers; and limiting children's exposure to the sun.

Former First Lady Barbara Bush, Her Royal Highness Lalla Slama of Morocco, Nigerian President Olusegun Obasanjo, and tennis star Steffi Graf are some of the powerful voices powering this campaign that UICC president Dr. Franco Cavalli says can save so many lives if embraced by those at the highest decision-making levels.

"Complacency and inaction on the part of world community will effectively contribute to more than 10 million deaths every year by 2020," he said.

I have dense breasts. And ever since the surgeon who performed my breast reduction surgery more than 10 years ago told me about the composition of my breast tissue, I have been a bit obsessed with how my breasts feel. Good thing -- because I ended up with breast cancer two years ago as a result of my own at-home monitoring. And now I wonder if my cancer was influenced by the density characterizing the tissue that fills my breasts.

Canadian researchers are reporting in a groundbreaking study that women with dense breasts, like me, are five times more likely to develop breast cancer than whose whose breasts have a lot of fatty tissue. It's long been knows that dense breasts inhibit the effectiveness of X-ray mammograms -- and perhaps delay diagnosis -- but now it's clear that breast density is a risk factor all on its own.

An ABC news team in Australia abandoned its Brisbane radio studio yesterday after an investigation revealed there is something about the workplace causing breast cancer.

It's not clear what the cause may be, but the five-month-long investigation concluded a breast cancer cluster is related to the office environment.

Twelve women who worked at the Brisbane Toowong office had been diagnosed with breast cancer over the past 11 years. Eight of these women worked in the newsroom. Most had been there for more than five years.

ABC managing editor Mark Scott would not move his staff earlier this year when 100 staff members walked off the job in July, demanding relocation. He said it would take evidence -- not just suspicion -- of a breast cancer cluster for him to agree to relocation. Now he has evidence.

The investigation report shows women who worked at this office reported breast cancer at a rate 11 times higher than the general working community.

In addition to the relocation, all female staff at Toowong office were offered free mammograms and free counseling services during the investigation. Yesterday, Scott extended the offer to women at other ABC sites in Australia.

BBC News is reporting that the conflict between Hezbollah and Israel has caused a massive oil spill off Lebanon's coastline that could take ten years to clean up and poses a threat of increased cancer risks for people living in the region. The spill was caused by the Israeli bombing of the Jiyyeh power station.

Yacoub Sarraf, Lebanon's environment minister, stated that they cannot begin to tackle the problem until the conflict ends. "We cannot get equipment, companies, labor or know-how to handle the problem," he said until the safety of technical teams can be guaranteed.

Marine experts from Inforac, an organization with links to the United Nations Environment Program (Unep), said the spill of fuel oil was a "high-risk toxic cocktail made up of substances which cause cancer and damage to the endocrine system." The experts warned that the first people at risk from the toxic spray at the time of the bombing were the two million inhabitants of Beirut.

Experts are comparing the oil spill to the Erika tanker oil spill off the coast of France and speculated that the Lebanon oil spill could end up being as devastating as the Exxon Valdez disaster.

Daughters born to mothers who were prescribed the anti-miscarriage drug diethylstilbestrol (DES), a synthetic estrogen, during pregnancy are at increased risk of developing breast cancer, according to research done by a nationwide team of researchers. Between the 1940s through to the 1960s millions of pregnant women were given this drug.

"This is really unwelcome news because so many women worldwide were prenatally exposed to DES, and these women are just now approaching the age at which breast cancer becomes more common," said the study's lead author, Julie Palmer, Sc.D., professor of epidemiology at the Boston University School of Public Health.

For a little history on DES, back in the late 1930s, physicians believed that low levels of estrogen in pregnant women led to spontaneous abortions or premature deliveries. But in the early 1950s, a clinical trial showed no drug benefit in preventing miscarriage. However, use continued in the US until 1971 when researchers determined that DES greatly increased the risk of developing rare cancers of the vagina and cervix in DES daughters.

I assume most DES daughters at increased cancer risk are already aware. However, what makes this news, is that researchers believe that if excess estrogen in utero might increase breast cancer risk later in life, the concern becomes one where other environmental factors that increase fetal exposure to estrogenic compounds need to be given serious consideration.

Researchers are beginning to tell us that being overweight increases cancer risks for a number of cancers. But then being overweight increases our chances of developing a number of diseases. While there are all kinds of diets, and gurus who claim they know the way, the remedy for long-term weight loss isn't going to change -- it's all about moving more, and eating less.

But what if you are moving more and eating less and the pounds stubbornly refuse to fall away? Amy Paturel, an expert in nutrition and public health, recently reviewed the top ten reasons why when you do all the right things, you aren't getting the expected results. The ten reasons Paturel discusses that can prevent weight loss are lack of sleep, synthetic chemicals in the environment, weather effects in temperatures being too hot or too cold, not smoking, prescription medications, giving birth at an older age, natural selection and overweight parents having overweight children.

Of course, this doesn't mean you are doomed to weight gain or being overweight but it might mean that you will need to take a look at some of the possible causes of why you are experiencing weight gain and not experiencing weight loss.

Paturel goes into an explanation of each of these causes in Ten More Fat Factors: It's Not Just the Cupcakes.

In the 11th report of the Committee on Medical Aspects of Radiation in the Environment (COMARE), children growing up in an affluent urban environment and children from rural areas are at higher risk for developing many cancers.

Researchers studied cancer clusters where leukemia and other childhood cancers were reported, and have come to the conclusion that affluent children are being raised in an environment that is too clean. Called the dirty hypothesis, children living in too sterile an environment where they are not exposed to infection have weak immune systems.

For rural children, infection brought in to the rural community by people from larger populated urban areas, might be causing genetic damage that leads to cancer.

With the exception of the processing plant at Sellafield in Cumbria, and Dounreay in Scotland, the researchers also state they found no general pattern of increased cancer incidence around nuclear plants.

The researchers feel confident in the reported results of this study. They invite further study into the hypothesis of their findings. The database was constructed from the National Registry of Childhood Tumours by staff of the Childhood Cancer Research Group in Oxford, and included 12,415 cases of childhood leukemia and non-Hodgkin lymphoma and 19,908 cases of children with solid tumors registered under the age of 15 in England, Wales and Scotland from 1969 to 1993.
