Contrary to what we are frequently told, we are not “losing the war on cancer”

A common narrative about cancer is that we are making no progress in our fight against it. Fortunately, the actual data do not agree. Yes, too many people still die of cancer and progress is slow, but it's not correct to claim that we are losing the war on cancer.

How accurately do physicians estimate risk and benefit?

A new study suggests that physicians tend to overestimate the benefits of treatments, tests, and screening tests, while also underestimating harms.

When science- and evidence-based guidelines conflict with patient wishes: What’s a doc to do?

We use the term "science-based medicine" (SBM) because medicine isn't a science. The best medicine, however, is based in science. Patient values are also important, but what is a science-based doctor to do when SBM conflicts with what a patient or family wants?

Uncertainty in Medicine

Medicine is an uncertain business. It is an applied science, applying the results of basic science knowledge and clinical studies to patients who are individuals with differing heredity, environment, and history. It is commonly assumed that modern science-based doctors know what they are doing, but quite often they don’t know for certain. Different doctors interpret the same evidence differently; there is uncertainty...

The hijacking of evidence-based medicine

A hero of the blog, John Ioannidis, worries that evidence-based medicine has been hijacked, and when Ioannidis says something we at SBM listen. But has EBM been "hijacked"?

On “integrative medicine” and walking and chewing gum at the same time

Evidence matters. Science matters. However, when advocates of "integrating" quackery into medicine via the vehicle of "integrative medicine" invoke weak science and poor quality evidence in conventional medicine in response to criticism, what they are really doing is deflecting attention away from their quackery. More importantly, advocates of science-based medicine are capable of walking and chewing gum at the same time. We...

How should we treat DCIS?

I’ve written more times than I can remember about the phenomenon of overdiagnosis and the phenomenon that is linked at the hip with it, overtreatment. Overdiagnosis is a problem that arises when large populations of asymptomatic, apparently healthy people are screened for a disease or a condition, the idea being that catching the disease at an earlier stage in its progression will...

Mandatory breast density reporting legislation: The law outpaces science, and not in a good way

Over the years, our bloggers here at Science-Based Medicine have written time and time again about the intersection of law and science in medicine. Sometimes, we support a particular bill or law, such as laws to protect children against religion-inspired medical neglect; laws making it harder for manufacturers of homeopathic “medicines” to deceive the public; or California Bill AB 2109, a bill...

Screening for disease in people without symptoms: The reality

One of the most contentious questions that come up in science-based medicine that we discuss on this blog is the issue of screening asymptomatic individuals for disease. The most common conditions screened for that we, at least, have discussed on this blog are cancers (e.g., mammography for breast cancer, prostate-specific antigen screening for prostate cancer, ultrasound screening for thyroid cancer), but screening...
