Fukushima Frustrations

Among evacuees.  The psychology behind by this statement is interesting:

" "Many residents feel that they have been forced to evacuate because of a man-made disaster, not a natural calamity," says Kanno. "Before, when bad weather or other problems occurred, everyone was on the same boat -- so people had the will to help each other. In the case of a natural disaster, people know that even if there are difficulties at the beginning, they can eventually start all over again even from scratch. However, when one is fighting against radiation pollution, starting a new life three, or even five years later is not easy. That is one of the characteristics of (the invisible damage caused by) radiation."

Congrats St. Jude Researchers

For discovering the underlying mutations associated with rare brain cancers.

Loss Of Big Picture Accident

There's been some new small leakage at Fukushima.

Why is that worthy of news coverage?

Guess what?  There will be lots of little leaks, small spills, puffs of contamination, etc.

That's what happens when one tries to work with the debris field that was Fukushima.

Stress - Cancer - Evolution

I always get a chuckle when some LNT-denier says something like, "we've evolved in a bath of radiation...small doses stimulate the immune system and are good for us".  If only I had a nickel for each time.

Yes, the bath of radiation is an environmental stress on our genes that causes genomic instability which promotes evolution.

That "stimulated immune system" is accompanying a reduction in genomic fidelity which leads to cancer.  Cancer is just evolution of somatic cells in the body's microenvironment.

Here's a new study which chemicals and yeast were used to test stress effects.

Dummy & Mummy

Some researchers have found prostate cancer in a 2,200 year old mummy.

We have evidence of human cancer before that.

But the more important point is in regards to "industrial factors" as mentioned in the former article.

Cancer happens because genes are disrupted....it isn't just "industrial factors" which cause that....natural radiation does that, certain foods do that, etc.  The same things which cause mutation which have given us speciation have given us cancer.  They aren't necessarily "industrial factors".

Anti-Vaccine Movement Similiarities To Anti-LNT Movement

Here's an abstract from an article about the anti-vaccine movement and the Internet.   The AVM poses a danger to children and society at large, by exaggerating the dangers of vaccines, thereby convincing some that kids should not be vaccinated.  This has lead to the resurrgence of some childhood diseases.

Of course the same concepts apply to those folks who suggest radiation is beneficial, thereby increasing the risks to the general public.  It also applies to those folks who exaggerate the risks of radiation, which may lead to stress, anxiety, etc. and cause people to take actions they wouldn't otherwise take.

That's what a recent study concluded between the years of  2002-2007.  Note that the increase is not apparent over the years of 1990-2007 (which include the smaller subset).  The authors are to be commended for pointing out a major weakness of these types of studies:

"Like most studies of childhood leukemia in the neighborhood of NPPs, the Geocap study did
not have access to complete residential histories, which is an important limitation for the
NPPs"

There are other weaknesses too, pointed out by the authors:

Fairewinds Associates Buffoonery

Was it a fool moon last night or what (just kidding)??? 

From the denial that radiation causes cancer by Atomic Ideologies Insights in my earlier post, to Flatulentwinds Fairewinds Associates exaggerating the radiation risks to Japanese children as a result of Fukushima.

Atomic Ideologies Buffoonery

The blog Atomic Insights (which is more ideology than insight) has a post which is a discussion about whether or not radiation causes cancer.  It's quite stunning to read the first paragraph where a Dr. George presents anecdotal evidence as scientific evidence.  And it continues to plunge downhill from there, with a Dr. Cuttler, who is claimed to have 15 years studying the health effects of radiation, yet quotes Dr. Wade Allison, who has said he has no expertise in the field.  And I have pointed out many of his scientific flaws in early posts which can be found in that last link.

Does The AAPM Understand Risk?

It doesn't sound like it, based on their recent statement.

We know that every dose of radiation has the potential to contribute to carcinogenesis.  That doesn't mean every dose will.  There's simply a risk that it will.

How can they say,  "Risks of medical imaging at effective doses below 50 mSv (milliSieverts) for single procedures or 100 mSv for multiple procedures over short time periods are too low to be detectable and may be nonexistent," said the statement released by the AAPM. "Predictions of hypothetical cancer incidence and deaths in patient populations exposed to such low doses are highly speculative and should be discouraged."?

Why, using modern epidemiology to devise these risks, are the risks "highly speculative" and why should they be discouraged?  What is the AAPM offering in return for our ignoring the science??

Nothing.

With all that said, most of the time the cancer risk associated with diagnostic imaging is less than the risk of not getting the information offered by the imaging.  But not always, sometimes doctors make mistakes.

If all works well.

Antibiotic Resistant Bacteria From Fukushima?

Well, at least he's not proposing Godzilla.  The answer is no.  Bacteria enjoy mutations a' plenty.  Fukushima isn't going to impact that significantly.  The antibiotic resistance originates when those bacteria exposed to an antibiotic survive and proliferate, whereas the non-mutants die.  There may be plenty of antibiotic bacteria in the environment, but we're not aware of them until we expose them to antibiotics.  Similarly, there are plenty of radiation sources, but there's no evidence that antibiotic resistant bacteria proliferate from around them.

Bon appetite.

More Fukushima Perspective From Japan

Citizens are taking matters into their own hands thanks to the internet and inexpensive monitoring equipment.

Meanwhile, the government vows a return to normalcy.

AntiEstrogen Therapy May Reduce Melanoma Risk

Some breast cancers are estrogen-receptor positive.  If you give them anti-estrogen (aromatase inhibitors) those cancers shrink.  A new study shows that melanoma risk may be reduced as well.

Hormesis & Right Wingers

Here's a book review on a book about radiation hormesis by someone affiliated with the Heartland Institute.  The HI is a right wing "think tank" which conducts public relations campaigns targeted at minimizing the role of government.  No surprise the review is favorable, since the ploy is that if radiation isn't bad, there's no need for government regulation.  The review ends with:

"No honest individual with an IQ above plant life could fail to see the terrible malfeasance of science regarding the LNT after reading this outstanding book."

At about $1 per page, the malfeasance is clearly with the author and publisher.  No way I would buy it just to refute it.  But I'll rebut some of its facets based on the review.  Let's see who has the IQ above plant life.

Exercise May Cut Bowel Cancer Risk

According to this study.  Yet, one has to be cautious with studies in which participants self report information.  A stronger study would have actually measured the level of exercise.  In any event, there are plenty of other of benefits to working out as well, so keep at it!

I am not surprised by this study which shows that cell signaling is also involved with regulating chromatin around which DNA molecules wrap.  In this way cell signaling can influence gene expression.  Now what if radiation can interfere with cell signaling, thereby changing gene expression, thereby promoting carcinogenesis?

Happy Anniversary War On Cancer!

I should have posted this last year (as in last week), but we've just celebrated the 40 year war on cancer.

This NPR article provides a great overview of the "war".

Dr. Harold Varmus (the interviewee) isn't only in charge of the National Cancer Institute, but he won the Nobel Prize for figuring out that some oncogenes (genes that can contribute to cancer if mutated) have their origins with RNA viruses. Those viruses, called retroviruses, become incorporated into their host cells' DNA and use the host to replicate. About 5% of the human genome contains retrovirus DNA.

We've made some terrific progress over 40 years, but most people living in the 1970's would have expected more, I suspect. That's because rather than being a single disease with a single cause, cancer is a fundamental, but very complex phenomenon associated with evolutionary biology and life itself. 

In 1900, tuberculosis was the leading cause of death followed by pneumonia in the U.S. By 1940, heart disease was first followed by cancer. And that's the rankings today.
