Breast cancer myths: No, antiperspirants do not cause breast cancer
Antivaccine activists frequently claim that aluminum salts used as adjuvants in vaccines cause autism. However, if you listen to the quacks and cranks, that's not all aluminum does. Oh, no, that nefarious metal is also being blamed for breast cancer. But don't throw away your antiperspirant just yet. The evidence cited to support this connection is utterly unconvincing. Much of it even...
Fluoride: Still Not Poisoning Your Precious Bodily Fluids!
We dentists are an evil group of sociopaths. When we’re not trying to kill you or give you chronic diseases such as multiple sclerosis with our toxic mercury saturated fillings, we are advocating for the placement of rat poison/industrial waste (i.e. fluoride) in your water supply by our governmental overlords. What is up with us? The problem is, we’re failing miserably. Even...
Legislating Ignorance
Science is under attack, and not just from anti-vaccine celebrities and parents with degrees from Google University. Scientific illiteracy is being woven into the very fabric of our society through legislative assault. If you dismiss this as alarmist hyperbole, you haven’t been paying close enough attention. Every day thousands of pediatric health care providers throughout the country provide safety advice to patients...
Pass the Salt (But Not That Pink Himalayan Stuff)
Humans, like many other animals, crave the taste of salt. Animals frequent salt licks, humans have traded salt for equal weights of gold, and the word “salary” comes from the Roman soldier’s allowance for purchasing salt. Salt appears in our language in idioms like “worth its salt” and “salt of the earth.” Shakespeare’s play King Lear is a variant of a folktale...
Ebola outbreaks: Science versus fear mongering and quackery
“Ebola virus particles” by Thomas W. Geisbert, Boston University School of Medicine – PLoS Pathogens, November 2008 doi:10.1371/journal.ppat.1000225. Licensed under CC BY 2.5 via Wikimedia Commons. Without a doubt the big medical story of the last week or so has been the ongoing outbreak of Ebola virus disease in West Africa, the most deadly in history thus far. Indeed, as of this...
NY federal court hands triple loss to anti-vaccination ideology
The state of New York allows religious and medical (but not philosophical) exemptions from school vaccination mandates. New York City has a policy of excluding unvaccinated schoolchildren from classes when there is an outbreak of vaccine-preventable disease reported in a particular school. Two sets of parents whose children had religious exemptions sued New York City and the state in federal court when...
In which Dr. Gorski is taken to task by an eminent radiologist for his posts on mammography
Introduction: An unexpected e-mail arrives One of the consequences of the growing traffic and prominence of this blog over the last few years is that people who would otherwise have probably ignored what I or my partners in blogging write now sometimes actually take notice. Nearly a decade ago, long before I joined this blog as a founding blogger, if I wrote...
Bill and Hillary Clinton go woo with Dr. Mark Hyman and “functional medicine”
Mark Hyman is a "pioneer" (if you can call it that) in a new form of quackery known as functional medicine, which combines a lot of the worst features of conventional medicine with a large dollop of "make it up as you go along" quackery. Unfortunately, it appears that the Clintons find his narrative compelling.
New evidence, same conclusion: Tamiflu only modestly useful for influenza
Does Tamiflu have any meaningful effects on the prevention or treatment of influenza? Considering the drug’s been on the market for almost 15 years, and is widely used, you should expect this question has been answered after 15 flu seasons. Answering this question from a science-based perspective requires three steps: Consider prior probability, be systematic in the approach, and get all the...
Mammography and the acute discomfort of change
As I write this, I am attending the 2014 meeting of the American Association for Cancer Research (AACR, Twitter hashtag #AACR14) in San Diego. Basically, it’s one of the largest meetings of basic and translational cancer researchers in the world. I try to go every year, and pretty much have succeeded since around 1998 or 1999. As an “old-timer” who’s attended at...
