Diet and exercise versus cancer: A science-based view
Yes, diet and exercise can be useful to prevent some cancers. Unfortunately, they don't prevent all cancers, and the effect size is more modest than often represented. That's not to say that eating right and exercise aren't good. They are, for so many other reasons than cancer. Just don't view them as a panacea for preventing cancer.
Therapeutic Touch Pseudoscience: The Tooth Fairy Strikes Again
A study out of Iran titled “Therapeutic touch for nausea in breast cancer patients receiving chemotherapy: Composing a treatment” was recently published in the journal Complementary Therapies in Clinical Practice. It is a great example of the Tooth Fairy science that permeates much of the research in complementary and alternative medicine. In Tooth Fairy science, researchers attempt to study a phenomenon without...
CAM use and chemotherapy: A negative correlation
"Complementary and alternative medicine" (CAM) is represented as safe because it is administered alongside conventional medicine, despite the fact that for the vast majority of CAM modalities there is little or no evidence for efficacy. However, as a new study shows, cancer patients who use CAM tend to be more likely to refuse conventional cancer treatment.
Reclassifying thyroid cancer and the willful misunderstanding of overdiagnosis
If there’s one lesson that we here at Science-Based Medicine like to emphasize, it’s that practicing medicine and surgery is complicated. Part of the reason that it’s complicated is that for many diseases our understanding is incomplete, meaning that physicians have to apply existing science to their treatment as well as they can. The biology of cancer, in particular, can be vexing....
Behold my power, quacks, and despair! Mike Adams publishes several defamatory articles about yours truly…
Internet crank, quack, and conspiracy theorist Mike Adams has launched a campaign of character assassination against yours truly. I didn't know I had so much power.
Acupuncture does not work for menopause: A tale of two acupuncture studies
Arguably, one of the most popular forms of so-called “complementary and alternative medicine” (CAM) being “integrated” with real medicine by those who label their specialty “integrative medicine” is acupuncture. It’s particularly popular in academic medical centers as a subject of what I like to refer to as “quackademic medicine“; that is, the study of pseudoscience and quackery as though it were real...
You’ve been diagnosed with breast cancer. How soon do you need treatment?
Timely surgery for breast cancer is obviously better than delaying surgery, but how long can a patient safely wait for surgery once diagnosed. Because a randomized controlled clinical trial to answer this question would be unethical, this has been a difficult question to answer. Fortunately, a new study provides an estimate of how much of a delay it takes before outcomes start...
Choosing Wisely: Changing medical practice is hard
One of the hardest things to do in medicine is to change practice in the face of scientific evidence that what you're doing isn't working. Quacks never change, but medicine does. The change might be slower and messier than we would like, but change does happen. Choosing Wisely is an initiative designed to bring about change by discouraging the use of interventions...
“Liquid biopsies” for cancer screening: Life-saving tests, or overdiagnosis and overtreatment taken to a new level?
I’ve written many times about how the relationship between the early detection of cancer and decreased mortality from cancer is not nearly as straightforward as the average person—even the average doctor—thinks, the first time being in the very first year of this blog’s existence. Since then, the complexities and overpromising of various screening modalities designed to detect disease at an early, asymptomatic...
“Precision medicine”: Hope, hype, or both?
I am fortunate to have become a physician in a time of great scientific progress. Back when I was in college and medical school, the thought that we would one day be able to sequence the human genome (and now sequence hundreds of cancer genomes), to measure the expression of every gene in the genome simultaneously on a single “gene chip,” and...
