How to find reliable online health information and avoid medical misinformation

Physician

March 31, 2026

Previously, I urged readers to use the internet for information about health conditions, medications, and other medical concerns to help make informed decisions about their care. I must modify this based on an online search experience I had that yielded mostly garbage. If I had not known what to seek, I would have been confused, ended my search prematurely, as I expect most people would have, and learned nothing.

To simplify …

Pharmaceutical advertising ethics: Why TV drug ads mislead patients

M. Bennet Broner, PhD

Conditions

March 10, 2026

Previously, I wrote about the patient’s responsibility to gain knowledge about their condition and treatments, and how this is not always easy to do. This is increasingly important, however, as clinicians have decreased time with patients for reasons often beyond their control.

This need for knowledge applies not only to medical visits, but also to advertisements for nostrums (e.g., Neuriva) and for legitimate drugs. Both create enticing visions on TV and …

Scientific literacy in nutrition: How to read food labels

M. Bennet Broner, PhD

Conditions

January 29, 2026

Dr. Andrea Love wrote about the lack of basic scientific knowledge among the public, noting that only about 28 percent of people possess it. She highlighted the consequences of this, emphasizing how it can negatively affect people’s decisions and lives.

Many of the articles I have written have dealt with scientific knowledge in one form or another. My comments on the FDA and drug approvals, Alzheimer’s and cancer screening blood tests, …

Physicians’ end-of-life choices: a surprising study

M. Bennet Broner, PhD

Conditions

January 3, 2026

In July, I wrote about the importance of end-of-life planning (EOL). Shortly after, I read a study that examined physicians’ EOL plans with advanced cancer and Alzheimer’s disease (stage unspecified). The study encompassed nations with different forms of aid in dying, from the U.S., where a terminal coma is the only option most states allow, to Belgium, where physician-assisted dying (PAD) and euthanasia are available. Although the term suicide …

Early Alzheimer’s blood test: Is it useful?

M. Bennet Broner, PhD

Conditions

November 29, 2025

In May, a published report indicated that changes indicative of Alzheimer’s disease (AD) were detected at age 24 via a blood test, which is increasingly available. These changes may begin earlier, but these were the study’s youngest participants. There are no medical treatments for these early manifestations, and aside from providing knowledge of a possible future and potentially causing anxiety, what value does the test hold? Unless a person has …

Are we scared of the wrong environmental toxins?

M. Bennet Broner, PhD

Conditions

November 1, 2025

Like you, I receive many emails concerning environmental toxins. Many of their claims are based on conjecture rather than scientific evidence and are delivered in a panicked manner, implying that you or a family member is doomed if you do not act quickly. It is especially annoying that they often target minor issues rather than major ones. For example, they have emphasized the danger of artificial sweeteners. However, if one …

How to spot bad science in medical news

M. Bennet Broner, PhD

Conditions

October 1, 2025

We often see media headlines or articles about scientific and medical advancements promising imminent treatments or cures. I am not referring to advertisements that frequently masquerade as stories for naturopathic, homeopathic, or other unproven remedies, but rather those from supposedly reliable sources, such as CBS, Yahoo, or the Chicago Tribune.

Reporters or news writers often compose them, despite lacking training in science or medical reporting. They frequently make inappropriate assumptions and …

The ethical crossroads of medicine and legislation

M. Bennet Broner, PhD

Conditions

September 8, 2025

Previously, I wrote about politicians regulating medical practice. I support regulations that protect individual or public health. However, when these laws are not evidence-based, misguided or frivolous, and potentially harmful, as occurred when 16 state legislatures permitted over-the-counter sale of ivermectin, they are unacceptable.

There have been instances when pregnant women, who, because of circumstances, were unable to adhere to physician advice for increased bed rest to avoid premature labor, were …

Why terminal cancer patients still receive aggressive treatment

M. Bennet Broner, PhD

Physician

July 31, 2025

Recently, researchers examined whether there had been any changes in the way terminal cancer patients died from 2014 to 2019, given the increased information available on hospice, palliative care, and advanced end-of-life planning (EOLP). They asked whether those who were terminal continued aggressive treatment until their demise. The authors anticipated a decrease in this, but found that the frequency of cancer patients who continued aggressive therapy had not declined. The …

Ethical dilemmas in using unclaimed bodies for medical research

M. Bennet Broner, PhD

Physician

June 23, 2025

In January, I wrote regarding the biased NBC report on unidentified bodies from a coroner’s office being used by a medical school. Subsequently, the network aired two related episodes.

The second report centered on a self-employed purveyor of bodies and parts. He displayed no respect for the people whose bodies or parts he sold. The report was disturbing, as there is an ethical difference between an individual profiting from these …

What Adam Smith would say about America’s for-profit health care

M. Bennet Broner, PhD

Policy

May 25, 2025

Over 80 percent of people are discontented with their medical insurance, whether provided by the government, their employer, or a commercial company. Common complaints are cost, increasing prices, and limited or rejected coverage. Regardless of the insurance’s source, we, the citizens, pay the bill through higher co-payments, deductibles, or premiums. Thus, their future payments increase when people request increased coverage for specific treatments, tests, or conditions.

However, individual desires are not …

Why shared decision-making in medicine often fails

M. Bennet Broner, PhD

Conditions

May 21, 2025

In numerous writings and venues regarding physician practice, the claim is made that “physician education is lacking in nutrition, geriatrics, care for non-cisgender people, relating to patients in general, cultural respect, equitable treatment, etc.” While all of these suggestions have merit, to what extent would they lengthen the already most extended medical school curriculum among developed countries? Or would those who advocate for these additions propose that they replace parts …

How corporate greed and politics are destroying health care

M. Bennet Broner, PhD

Policy

March 26, 2025

In past decades, physicians practiced medicine. The majority were dedicated to patient well-being. They were paternalistic and decided what was in their patients’ best interests, and patients generally trusted their judgments. In the 1970s, ethicists concluded that patients and clinicians should make treatment decisions jointly. This position has been championed since then, despite multiple surveys demonstrating that more than 50 percent of patients prefer their physicians to be the decision-makers. …

Patient choice vs. patient life: Which is the greater good?

M. Bennet Broner, PhD

Physician

February 26, 2025

In a 2023 study, researchers explored the medical needs of elderly, mentally deficient individuals who lived alone. A common comment by interviewed physicians was that they knew some patients required greater supervision or care, but they acceded to patient choices to return home. Are clinicians placing too great an emphasis on competency and patient rights rather than on patient well-being?

Everyone knows the phrase: “First, do no harm.” Yet today, deciding …

How unclaimed bodies are fueling a medical ethics firestorm

M. Bennet Broner, PhD

Conditions

January 14, 2025

Last September, NBC News aired a one-sided report on the arrangement between a county coroner and a medical school apropos the transfer of unclaimed corpses with reportedly inadequate effort to find family. In addition to a grieving family, an academic bioethicist was interviewed who expressed horror at the transfer procedure. The report did a disservice both to bioethics and to necessary medical training and research.

In a similar incident, a coroner …

Are new blood tests for Alzheimer’s and cancer worth the hype?

M. Bennet Broner, PhD

Conditions

December 21, 2024

Recently, consumer articles heralded that blood tests for detecting Alzheimer’s dementia (AD) and many cancers were close to clinical availability. Given the narrow window in which AD must be diagnosed for present treatments to be effective, and questions regarding the utility of early cancer detection, will these tests provide any patient advantage?

Presently, there are two medications to treat AD. Neither is curative, but they slow disease progress by about five …

PTSD: Why trauma’s impact is more complex than you think

M. Bennet Broner, PhD

Conditions

November 16, 2024

According to the National Institutes of Health, the majority of individuals experience several traumatic events in their lifetimes, but do they all develop post-traumatic stress disorder (PTSD)? If you question the general populace or the media, they would indicate that PTSD is extremely common. Although it varies by sub-population, for the general populace, 13 and above, the rate of diagnosed PTSD is 4 percent to 8 percent. It is highest …

Nurses sue over trans colleague’s actions

October 22, 2024

Eight female nurses at a United Kingdom hospital are suing their employer for not assuring their psychological and physical safety. The nurses work in specialized areas that require their changing uniforms once daily. There is a trans-female nurse, similarly specialized, who changes with them. He wanders about the locker room in briefs or nude, the women report, ogling them as they exchange clothing. It has also been related that he …

Why representation alone won’t solve health care equity issues

M. Bennet Broner, PhD

Education

September 12, 2024

I attended a workshop on developing equitable health information materials, emphasizing that people are more responsive to data when individuals of similar complexion and/or features are represented. This concept originated in education, where research indicated that youth learned better from teachers with similar characteristics, and it was subsequently extended to health care. However, universal application is unrealistic, as Black children will not always have Black teachers, and patients of color …

Talcum powder and female cancer: Separating myths from facts

M. Bennet Broner, PhD

Conditions

August 6, 2024

Another recent correlational study on the relationship between talcum powder (TP) and female reproductive tract cancers was published. This research originated in the 1970s when gynecologists at one hospital noted that an unusually high number of women were experiencing these cancers. They reviewed medical records and, in looking at possible causative agents, noted that many of the affected women used TP. They published their findings, and additional case review studies …
