Most health care professionals advice the use of sunscreen for everyone - but unlike people, sunscreens are not all created equal. The Environmental Working Group investigated 1,015 brand name sunscreen products. Of these they found that only 25% were both safe and effective. The issues:

Ingredients that pose significant safety concerns:

In addition to ingredients that may be irritating or cause allergic reactions, some chemicals in common sunscreen products raise greater concern. Some of these can be absorbed through the skin and mimic estrogen in the body. Some can actually have a skin-damaging effect by forming free radicals when exposed to sunlight.

As we are bombarded by advertising that touts everything from “healthy fast food” to miracle pills that can ease every malady known to man, how does your sunscreen measure up? The Environmental Working Group’s “Skin Deep” cosmetic safety base lists 20 sunscreen products that are considered both low hazard and effective here.

The FDA plans on Upgrading Sunscreen Labeling to include information on UVA protection.

Mom always told us we needed to spend time in the sun, but watching sunscreen commercials makes us wonder if we should venture beyond the front door unless the moon is shining. Do we really need sunshine? And if so, do we dare step outside for 10 minutes without sunscreen?

According to the National Cancer Institute, up to 50% of those living in the US are at high risk for vitamin D deficiency. Vitamin D deficiency has been linked with several cancers as well as conditions such as osteoporosis and cardiovascular disease. Over the past year, studies have been published demonstrating a significant reduction in the incidence of breast cancer, lung cancer, and colorectal cancer in those receiving the equivalent of 1000 IU’s of vitamin D daily. For those who have been diagnosed with cancer, increased survival geographically going from north to south has been correlated with sun exposure, and hence vitamin D.

So how do we get vitamin D? Historically, sun exposure has been the main source of vitamin D. While our approach has traditionally been to recommend dietary sources of vitamins alone, this is difficult with vitamin D. Even with vitamin D fortified foods, to get 1000 IU’s per day would require drinking 10 glasses of milk! The Canadian Cancer Society has advised that individuals should consider taking a supplement of 1000 IU’s of vitamin D daily during the fall and winter months. In the US, the American Society states that some people may require supplements, and this should be discussed with your health care provider.

What do the authors do? Spending 10 to 15 minutes in the sun without sunscreen (sunscreen with an SPF > 8 blocks formation of vitamin D) in average summer attire, can result in the absorption of a whopping 5000 IU’s. Of course, this is not recommended for everyone, sun protection (hats, sunscreen) should be used after this time, and you should never burn.

But what if it is cloudy? Many things affect how much vitamin D is produced in our bodies by sunlight, including latitude, complexion, season, and time of day. Clouds reduce absorption by 50% and shade by 60%. People with fair complexions require much less sun exposure to absorb vitamin D than those with darker complexions. At latitudes above 40N (northern California), very little vitamin D is produced during the winter months, and hence the Canadian Cancer Society’s recommendation for a supplement.

Have a Sunny Day!

Amidst the spring shower of sunscreen advertisements, we forget there are many ways to lower our risk of developing skin cancer. What we eat can have an impact on whether we will ever have to hear those words, “you have skin cancer!”

It has been shown that those who consume more fruits and vegetables have only half the incidence of skin cancer, whereas those who consume meals high in meat and fat have twice the risk. A few “superfoods” have been shown to pack an extra punch, and make a great addition to a picnic on the beach.

Superfoods for Skin Cancer Prevention:

1. Artichokes - Artichokes are high in silymarin, an antioxidant that has been shown to slow the growth of melanoma cells in mice.

2. Green tea - Epigallocatechin-3-gallate (EGCG), a component of green tea, has been shown to protect the skin of rodents from UV damage. A great treat chilled on the beach!

3. Fish - Omega-3-fatty acids in fish appear to offer protection against non-melanoma skin cancer.

4. Grapes - Proanthocyanidins, present in grapes seeds, have been shown to prevent photocarcinogenesis (cancer caused by sun exposure.)

5. Broccoli sprouts - Sulforaphane, which is high in broccoli and especially broccoli sprouts, was shown to substantially inhibit UV induced skin cancer in mice.

6. Berries - Berries are high in ellagic acid, which appears to have anti-tumor properties in rat skin.

7. Pomegranate juice - An juice extract of pomegranates was shown to protect against UV damage on a molecular level.

8. Carrots - Foods high in beta-carotene appear to have a protective role against skin cancer.

9. Spinach - Spinach is high in lutein/zeaxanthin, which has been shown to reduce UV induced skin cancer in mice when consumed dietarily.

10. Pineapple - Pineapple contains bromelain, a compound shown to decrease cancer in animals.

Practicing common sense, such as using hats and avoiding midday sun exposure are paramount. After all, melanoma, responsible for 75% of skin cancer deaths, had an incidence of only 1 in 1500 people in 1935 when common sense was not exchanged for the blissful feeling that a chemical could protect us from all harm. This incidence of melanoma is now 1 in 84.For further information on cancer prevention, visit Avoiding Cancer One Day At A Time.

A quick click of the remote in spring, and it isn’t long before we hear how we must prevent skin cancer. Prevention, we are told, comes in a multitude of colorful bottles with assorted numbers and can even be applied in colors that dissolve, to make certain every patch of skin is concealed. Could it possibly be that there are “natural” things we can do to lower our risk, in addition to the ubiquitous sunscreen?

Researchers demonstrated in the past that mice who spent more time on the treadmill, had a lower risk of skin cancer. Last summer, another dimension was added. Mice that ran on a treadmill plus drank the equivalent of 1 to 2 cups of coffee, had a 400% increase in apoptosis of skin cells that had been damaged by UVB rays. “Apoptosis” means cell suicide, the process by which abnormal cells die rather than progress on to become cancer cells.

We all know that “stressed out” feeling. Too much to do. Too little time.

And, we know intuitively that stress is not healthy.

But we also know that some people seem to endure endless stressful events in their lives and come out healthy. Others, faced with fewer of these events, but feeling overwhelmed nonetheless, do not fare as well.

The research seems to support our intuition, and the observation that the actual stressful events in our lives are less to blame than our perception of and reaction to them. Credible studies have found an increased risk of developing both breast and cervical cancers in those experiencing more stress. The actual stressful events in these studies did not play a role, rather it was the subjective sensation of stress that was correlated with a risk of cancer. So what can we do to lower our “feelings” of stress?

It is well known that people in different regions of the world have rates of breast cancer that vary considerably. Is this simply because the genetic makeup of certain populations differ? Japanese women have a low rate of breast cancer. If they move to Hawaii, their risk increases, and risk increases further yet if they move to the mainland United States. Clearly genetics alone cannot explain this. So - what does? Studies are increasingly pointing at the role of diet as one explanation.

A recent study looked at the Mexican diet, since Hispanic women have a lower incidence of breast cancer than white non-Hispanic women. It was found that those who consumed a native Mexican diet(right), or a Mediterranean diet(below), had a significantly lower risk of developing breast cancer than those who chose to partake of the traditional western diet.

Last year, a study looked at women who consumed a typical “soy-vegetable” Chinese diet, versus the western diet. Those women who switched over to a western diet had a 60% increased risk of developing breast cancer.

Sadly, countries such as China in the above study, that are adopting our “meat-sweet” western diet, are also beginning to experience our high breast cancer incidence as well.

Action point: Lowering the risk of breast cancer can be fun with this knowledge. Go to your library, bookstore, or online, to find ethnic recipes that look enticing.

Spring has arrived! For those in the north, the sound of lawn mowers and sprinklers strum heavenly chords in our souls after a long winter. We think of health and vitality as we watch our children roll in the grass, and exchange boots for bare feet. Is it possible that such a tranquil vision could be concealing a very real danger?

Sadly, it has been demonstrated in credible studies that children exposed to home and garden pesticides have a significantly elevated risk of developing leukemia and lymphomas. Have you seen those signs posted by commercial lawn companies to keep dogs off the lawn for a period of time? Dogs that live in households that use herbicides containing 2,4-dichlorophenoxyacetic acid (a chemical found in most common weed killers), are twice as likely to die from cancer. In that study, dogs were looked at because it is felt they have more contact with the lawn than humans. As a mother of boys I stand to disagree! Is this really a concern? According to the Environmental Protection Agency, Americans apply 90 million pounds of herbicides and pesticides on their lawns every year.

OK. You understand the risk. You decide to skip the weed killer and let nature rule. But how do you keep up with - or have a lawn that is somewhat presentable living next to - the Jones’s that make their lawn a priority? A few tips:

Mow high and often

Add grass seed to thicken the grass and choke out weeds

Consider mulching

If you choose to fertilize, choose “organic” fertilizers from a reputable nursery. Many nurseries now carry alternatives to chemical weed killers as well

If weeds are a concern, trying pulling them, killing them with hot water, replacing lawn with rocks or other forms of landscaping, or simply tolerating them.

Remember, “Weeds are flowers too, once you get to know them.” -Eeyore, from A.A.Milne’s “Winnie the Pooh”

What would a summer picnic be without the grill going? Yet, studies show us that eating grilled foods may raise our risk of developing cancer. As we spring into the summer months of picnics, parties, and that wonderful aroma and taste of grilled food, what can we do to celebrate the taste of the season, without raising our risk of cancer?

Tips for Cancer Prevention:

1. Use Natural Charcoal. Conventional charcoal may contain additives/toxins, including those labeled as carcinogens.

2. Use a fire chimney instead of lighter fluid. Lighter fluid contains petroleum distillates, known carcinogens.

3. Choose rare over well-done with beef (with the exception of hamburger that should always be well-done). Those who choose their cuts of beef rare or medium rare appear to have a lower risk of stomach cancer than those who prefer them well-done.

4. Marinate meats for an hour before cooking. Marinating meats greatly reduces the formation of heterocyclic amines, cancer causing substances produced in grilling meats.

5. Grill vegetables. Grilling vegetables does not result in the formation of the cancer causing substances that can occur with grilling meat, and has the added benefit of adding to the list of “5 to 9.”

Eating 5 to 9 servings of fruits and vegetables a day lowers the likelihood that you will have to hear that dreaded phrase, “You Have Cancer.” For further information on cancer prevention, visit the web site for Avoid Cancer One Day At A Time.

March Is Colorectal Cancer Awareness Month!

How many of us have lost a loved one to colorectal cancer? Too many - since colon cancer is the second leading cause of cancer deaths in the USA. Thankfully, at least 60 percent of colon cancer deaths can be prevented by timely screening alone. In addition, certain lifestyle practices may lower the risk of developing polyps or cancer in the first place. Here is our top ten.

1. Relish salads - Green leafy veggies are high in folic acid, vitamin B6, and lutein, all of which are associated with a lower risk of developing colorectal cancer. Top them off with a little extra virgin olive oil based dressings and a few berries for an extra punch.

2. Step into the sun - Vitamin D obtained through moderate, sensible sun exposure, has been shown to significantly lower the odds that colon cancer will darken our lives.

3. Give beans about it! - Countries with the highest bean consumption have a lower death rate from colon cancer. As an extra step, saponins, a phytochemical found in beans, might prevent colon cancer cells already present from multiplying.

4. Stand up and dance - Women who exercise more than four hours per week, drop their risk of colorectal cancer 40 percent.

5. Stay away from “cancer sticks” - Studies on smoking and colon cancer are inconsistent, but the risk of rectal cancer is nearly doubled for those who puff.

6. Consider fiber more important than a component of cute clothes - While U.S. studies fail to show a protective effect of fiber on colon cancer, European studies with a higher intake of fiber (35 grams) show promise. A study published in the journal Lancet suggests that people with a low average fiber intake can drop their risk of colon cancer by 40 percent - simply by doubling daily fiber.

7. Go Whole - Whole grains appear to lower the risk - especially the risk of rectal cancer.

8. For us ladies - The calcium we use to keep our bones strong does not appear to lower the risk of colon cancer, at least in postmenopausal women, but it does make it less likely that we will experience regrowth of colon polyps - some of which can lead to cancer.

9. Don’t dedicate your life to your job - Certain occupations, such as fire-fighting, raise the risk of colon cancer. Familiarize yourself with workplace risks. More on this later.

10. Be a lean machine - Obesity, especially in men and younger women, raises the risk of developing colorectal cancer. Our January 11th blog entry describes the connection. In the studies “younger women” are considered those aged 50 to 69. Parden me while I retreat to send a love note to that researcher that makes me a babe!

Of course, screening is very important in lowering deaths from colorectal cancer. Current guidelines can be found here. Taking a thorough family history and sharing it with your health care provider is imperative. In some cases, screening should begin much earlier. Many people put off screening - and for a multitude of obvious reasons! See our recent post for insights on turning this dreaded task into a cause for celebration!For further information on cancer prevention, visit our web site, or read “Avoiding Cancer One Day At A Time: Practical Advice for Preventing Cancer.”
