Most solid cancers have a long list of well-documented ways to prevent them. Treatment, however, remains shaky. Breast, prostate, colon and pancreatic cancers are all very preventable.

But the lifestyle choices known to prevent these deadly cancers are not always easy. Luckily, many of them are easy to implement and live by. More troubling, however, are the risk factors that you may not be aware of or that you can’t change.

Exposures in the womb are something that you can’t go back and change. It is established that chemicals like diethylstilbestrol (DES) that was given to pregnant women in the 1960s increased the risk of breast cancer in the moms as well as the female children later in life. Other estrogen-like environmental chemicals like BPA and phthalates have been linked to breast cancer and it is highly likely that exposure in the womb would increase breast cancer rates later in life as well.

Things that happened to you as a teenager can have a lifelong effect on breast cancer rates. You age when you started menstruation, how much sun exposure you got and how much soy you ate as a teen are all influential factors.

But what about your own personal circadian rhythms?

“My what?”

I’m not talking about a blues band from Atlanta. I’m talking about your body’s daily rhythm as it pertains to day and night. We are NOT nocturnal creatures. We’ll leave that to the bats. We should be sleeping at night.

Despite this, sleeping disturbances are quite common in society. Insomnia, sleep apnea, restless legs, late nights and problems falling asleep plague society. Much of this is because we are so stressed that we can’t relax enough at night to settle into a restful night’s sleep.

Then there are the midnight-shift workers and airline personnel that are frequently changing time zones. This group of people have problems with their circadian rhythms because of their work schedules.

There are documented health problems that midnight shift workers experience. Weight gain and obesity are on the top of the list. Higher rates of breast cancer have also been demonstrated.

Which brings us to this particular article. In it, researchers take a much deeper look at the relationship between sleep disturbances, light exposure at night and breast cancer risk. In this study, female mice at an increased risk of breast cancer (along the lines of a BRCA mutation) were evaluated to see what kind of effect swapping dark and light exposure had on tumor growth over a lifetime. At the end of each week, the mice were exposed to a full 24-hour period of either light or dark.

The results were a little shocking:

Switching up light and dark led to a decrease in the body’s ability to stop tumor growth, leading to an increased numbers of tumors that developed faster.
In addition, there was an increase in body weight.
These mice also slept much more, increasing sleep times by 50% (which led to a reduction in overall physical activity)

Based on this study, it is clear that messing up the normal day-night rhythms that we are all designed for creates problems. There are a number of ways in which this might occur, such as:

Suppression of the brain-protective melatonin by light exposure at night
Stress from sleep disruption
Alterations in lifestyle due to sleep disturbances (smoking, unhealthy diet, altered timing of food)
Decreased vitamin D levels due to lack of sunlight exposure

Whatever the reason, the links continue to be proven. If you are one of these people that gets exposed to light at night, here are some tips:

For insomnia, stress is likely an issue. Rather than relying on meds, find someone to help you with the underlying problem and fix it.
Sleep apnea? The long term answer is an anti-diabetic lifestyle. In the short-term a CPAP machine is a must.
Wearing a sleep mask can help block your nighttime exposure to light that can disrupt sleep.
Specialized glasses to block blue light can be used in the evening to help combat sleep problems.

If you have a job that requires the midnight shift or lots of travel to different timezones, there may not be a lot you can do in this regard. However, there is still a long list of lifestyle choices that go a long way to combat your sleep / wake cycle disturbances. These choices become that much more important.

Have Breast Implants? 3 Things to Know About Your Breast Cancer Risk

August 31, 2013 by James Bogash

I’m going to need to tread lightly on this one because I can understand, from an evolutionary standpoint, the near irresistible pull of the eyes towards the natural as well as the aftermarket products.

But underneath it all, regardless of how they look, we still need to be concerned about protecting the breast against the scourge that is breast cancer.

As a way of background, breast augmentation in the US is the most popular cosmetic procedure performed, numbering 307 000 surgeries in 2011, an increase of approximately 800% compared with the early 1990s. I’m pretty sure almost all of these are done here in Scottsdale, AZ, which explains the expensive European sports cars in the medical buildings here.

Early on, there were many concerns over the initiating of an autoimmune reaction to silicone implants, but research over the years has not found great evidence to support this notion. What has been clear, though, is that the density of the implants get in the way of interpreting mammography studies (as well as jump roping, but that is beyond the scope of this article).

According to this particular study, this creates a problem. A 26% problem to be exact. Researchers looked across multiple studies to get a clearer picture of whether implants led to a greater risk of being diagnosed with breast cancer at a later stage. As mentioned, they found a 26% higher risk that women with implants versus women who did not have implants would be diagnosed at a stage that has metastasized.

Worse, the researchers looked at another group of studies on the actual survival rates in women with implants who developed breast cancer. Overall, there was a 38% lower risk of 5-year survival in these studies.

Now, lest you are already picking up the phone to call your plastic surgeon to schedule their removal, there are a very important things I need to point out:

The authors noted some concerns with the studies themselves that were looked at, and so it may be too early to draw firm conclusions.
Overall, your individual risk of surviving breast cancer does not change much, about 88% survival down to 84%.
Regardless of how it plays out, breast cancer is highly, highly preventable. This means that, as a proud implant owner, there is less leeway for unhealthy behaviors leading to an increased risk of breast cancer.

The long list of thing you can do to lower your risk of breast cancer is beyond the scope of this post, but you can read more about these by looking through previous articles by clicking here.

So, if you already have implants and have no desire to have them removed, it’s time to evaluate your lifestyle and make the necessary changes. It’s not an option.
