Breast Cancer Risk Associated with Lignans – (10-10-02)

Breast Cancer Risk Associated with Lignans Differs by CYP17 Genotype

Ditto. All of us here, right now, are observed the dawn of the future of medicine. Granted, it may be several generations before mainstream medicine actually begins to read their own journals and pick up on this stuff. We are seeing the matching of lifestyle factors to the genes of a patient. In the near future, a simple genetic test may be able to spell out what YOU need to do to drastically lower or eliminate your risk of most chronic diseases. And this knowledge is not far off at all…probably no more than a few years at most.

Breast Cancer News: 4 Things Women Under 40 NEED to Know

by

Given that I’m running about a 3 week backlog on emails, you’ve probably heard this information before because it’s been all over the news.  Regardless, it does not get any scarier then this.

I will try not to sound like a scaremonger, but I have frequently mentioned that we have not begun to see the tip of the chronic disease iceberg yet.  With the exception of pockets of healthy individuals, our lifestyles continue to degenerate at a time we are exposed to more processed foods and environmental chemicals.  Children being born today are exposed in the womb and grow up in a toxic environment.

The list of chronic diseases contains the usual players, but when it comes to cancer, the story is a little different.

I have certainly given my opinion on the research as it relates to breast cancer prevention and early detection methods like mammography.  Mammography has been the center of a heated debate recently due to the unacceptably high number of false positives combined with the number of women who were diagnosed with breast cancers that would have resolved without any treatment.  I have covered this concept in a previous blog article that can be read by clicking here.

While all this debate has been going on, no one has focused on the true problem, which is the shoddy effort at educating women about how to prevent breast cancer.  You see, without this education, the rates of women with breast cancer can only increase.  The recent debate over mammography has to do with whether women aged 40-50 should get a mammography, and we’ve wasted an awful lot of energy and resources on the debate.

In the meantime, some scary stats are emerging in the background that are completely unaffected by the debate on whether to perform mammography on women 40-50 years of age.  The rates of more advanced breast cancer cases is on the rise in the 25-39 age group.

This particular study looked at what was happening in the rates of breast cancer in this age group from 1976 until 2009.  Here’s what they found:

  • Breast cancer with metastasis at diagnosis increased 2.07% per year
  • The steepest increase was from 2000-2009, during which incidence rose 3.6% per year.
  • There was no stage migration found (in increase in another stage of cancer due to better diagnostic tools) from regional, localized, or in situ categories, none of which had a decline in incidence at any time since 1976.

So what does all this mean?

  1. Stage IV breast cancer rates are increasing in the 25-39 age group.
  2. This level of cancer is much more difficult to treat.
  3. This is not the population that we actively pursue early detection.
  4. No level of staging has gone down since 1976.  In other words, things are getting worse.

Let me say this as clearly as I can.

While the fight rages on and on about who should get screened when, more dangerous cancers in younger women is clearly on the increase.  Screening will not help this population.  The ONLY thing that could have and will help is to  get our collective heads out of our asses and start to educate women about prevention.

Anything less will be a disaster.

Adolescent diet and risk of breast cancer – (06-23-03)

Adolescent diet and risk of breast cancer

While it should come as no surprise that the diets we eat in our teenage years will affect our risk of cancer down the line, at some point our national organizations (AHA, American Cancer Society, American Dietetic Association) need to wake up and smell the coffee. As a nation, we do a sickeningly poor job at prevention given the sheer volume of preventative measures. Now, at a time when the bar is raised further (i.e. educating our teens…) our national organizations maintain the status quo.

Mutations in BRCA1 and BRCA2 and predisposition to prostate cancer – (07-14-03)

Mutations in BRCA1 and BRCA2 and predisposition to prostate cancer

Too many people do not make the association with a family member with either breast cancer or prostate cancer if they are of the opposite sex. However, there are numerous pathways by which these can be related. I was already aware that the way our bodies breakdown estrogen (identified in research as the 2/16 hydroxylation ratio) is a risk factor for both breast, endometrial and prostate cancer.

How to Prevent Breast Cancer: Does Mammography Help?

by

All women want to learn how to prevent breast cancer. For far too many, this equates to mammography, since this helps with early detection. Is this good enough?

 Before we go any further, I need to make one thing very, very, very clear.  Mammography is NOT prevention.  I cannot tell you how many times I have been given this answer while volunteering at the Komen 3-day when I ask walkers what they are doing to prevent breast cancer.  If women participating in a massive event like the 3-day do not understand the term prevention, we can assume the rest of the country has some learning to do as well.

All screening procedures do that: they screen for cancer or precancerous lesions.  It is an attempt to find things before they get to the later, more difficult to treat stages.  This sounds like a great idea.  Or, at least it would, were it not for 2 very major problems.

First, as a society, we have a tendency to forgo true prevention in lieu of early detection.  The walkers at the 3-day I have come across are evidence of this.  An event this large, with this much exposure, and no one seems to understand that you really can prevent breast cancer.  This is, of course, despite hundreds and hundreds (if not thousands and thousands) of research studies suggesting otherwise.  On the flip side, every 3-day walker knows that it takes mammography to find that tumor early.

Second, what if there are significant harms in early detection?  We all bask in the false knowledge that there is no such thing as bad screening and early detection of everything.  This is certainly not the first time I’ve talked about the problems associated with overdiagnosis of breast cancers due to mammography (one previous blog post can be read here).

This particular study takes another hard look at what mammography is costing our society.  Here are  a few of the findings:

  1. The introduction of screening mammography in the US doubled the number of cases of early-stage breast cancer that are detected each year.
  2. However, the rate at which women present with late-stage cancer has decreased by only 8%.
  3. Overall, out of 100,000 women, mammography led to 122 women being diagnosed with early stage breast cancer.  Only 8 of these will progress to advanced cancer (Tweet this).

With some number crunching, the authors estimated that, in the past 30 years, 1.3 MILLION women were diagnosed with breast cancer that would not have progressed.  In 2008 only, this number was 70,000 women (31% of all breast cancers diagnosed).

And we all know what happens to any women who is diagnosed with breast cancer: additional testing, biopsies and potential subsequent treatment with surgery, radiation, chemo or some combination thereof.

1.3 million.

Of course, one side of the argument would be that we just don’t know which of these 8/100,000 women are going to progress to advanced cancers.  This is certainly valid.  But how much more money would we be able to throw at research to answer this question if we weren’t wasting billions more on treatments that aren’t needed?

Caloric Restriction and Incidence of Breast Cancer – (03-22-04)

Caloric Restriction and Incidence of Breast Cancer

Knowing that caloric restriction without nutrient restriction is the only “anti-aging” approach that consistently extends life span in mammals, the results of this study should not surprise anyone. However, I will not exactly advocate anorexia followed by pregnancy to lower your risk of breast cancer (which is what this study evaluated), but a whopping 76% reduction is breast cancer risk is incredible. Most likely the lowered risk is tied in with insulin signaling somewhere.

Links between iodine deficiency and breast cancer – (01-29-04)

by

The thyroid, iodine and breast cancer

This is a very interesting concept brought to my attention by Dr. Harry Eidner’s newsletter produced for DSD International. Their seems to be some links between iodine deficiency and breast cancer. The additional of treatment for hypothyroidism seems to strengthen to risk of breast cancer. Given the high level of prescriptions for hypothyroidism (most notably Synthroid) this is a very real concern.

Dietary phytoestrogens and breast cancer risk – (02-16-04)

by

Dietary phytoestrogens and breast cancer risk

These researchers found no protective effect of dietary phytoestrogens (lignans and isoflavones) on breast cancer. However, if I might recall the research that suggested no protective effect of fiber on colon cancer risk. In both these cases, I could mutate the popular saying into “It’s the flora, stupid!!”

In neither of these studies were the participants stratified for GI flora. In both situations, the presence of a healthy bacterial flora that converts the protective compound (soluble dietary fiber into short chain fatty acids like butyrate, isoflavones and lignans into equols and enterolactones, respectively) into its active form may be the mechanism by which these compounds protect the body.

Just another example of the complex and important interactions between different aspects of human (and, in this case bacterial…) physiology that are many times missed by researchers.
