Prostate Cancer and Social Media Misinformation

A recent study published in European Urology Oncology, a journal specializing in cancer and urology research, found that misinformation about prostate cancer is widespread on three of the most popular social media platforms — TikTok, Instagram, and YouTube — in both English and Spanish.

The study found TikTok had the highest prevalence of misinformation, appearing in 40 percent of posts about prostate cancer, compared with 6 percent on YouTube and 7 percent on Instagram. Researchers also noted that inaccurate information was nearly equally common in English- and Spanish-language posts, at 18 percent and 17 percent, respectively.

Prostate cancer is a type of cancer that affects the prostate, a small gland in men located below the bladder and surrounding the urethra. The prostate plays a key role in producing seminal fluid.

Prostate Cancer Misinformation Influences Public Behavior

Researchers analyzed 300 posts using the search terms “prostate cancer” and “cáncer de próstata”, collected from 50 English-language and 50 Spanish-language accounts on each platform. They also interviewed 23 doctors, healthcare workers, and community educators involved in prostate cancer care in the United States to examine the types and sources of misinformation in these posts.

The study found that 18 percent of posts contained misinformation, while 34 percent included misleading information in the comments. Researchers also noted that 62 percent of posts with misinformation prompted people in the comments to change their behavior based on that content.

Dr. Staci Loeb, the study’s lead author and a urology specialist, said, “We do not know why misinformation spreads so widely on TikTok, or what motivates people to share inaccurate information. But it is the responsibility of medical professionals to counter this misinformation with facts.”

Some Prostate Cancer Content Creators Falsely Claim To Be Doctors

The study found that most errors involved lifestyle and nutrition, cancer screening and early detection, and treatment. Examples of misinformation included claims that prostate cancer is sexually transmitted, that it can be treated with herbal teas, juices, or medications such as melatonin, ivermectin, or fenbendazole, or that men should avoid biopsies because they cause cancer.

Researchers noted that some individuals sharing this misinformation claimed to be doctors but lacked the necessary medical credentials to advise on prostate cancer. Of 13 “doctors” who posted misleading information, none were board-certified in urology, medical oncology, or radiation oncology, except for one physician certified in internal medicine who treats prostate cancer.

Dr. Staci Loeb said, “This is especially concerning because doctors are widely regarded as trusted sources of health information. It is vital for viewers to verify the credentials of anyone sharing medical guidance.”

Misleading Prostate Cancer Videos Reach Millions of Views

The researchers reported that posts from these self-proclaimed doctors reached up to 4.1 million followers, and prostate cancer videos on YouTube sometimes received more than 1.3 million views, even though three-quarters of the content in the posts or comments was misleading or biased.

Dr. Staci Loeb said, “Medical professionals should provide patients and their families with a ‘prescription’ of reliable, relevant information sources and actively share evidence-based guidance.”

The study highlighted the need for caution and careful verification of health information sources, particularly on social media platforms where misinformation can spread rapidly.

Misinformation About Prostate Cancer Is Widespread

For years, misinformation about prostate cancer—its risks, prevention, and treatment—has spread widely on social media. Research shows this is not an isolated issue but a pervasive problem across major platforms, influencing patient decisions and creating major challenges for awareness campaigns, early detection, and evidence-based care.

A 2019 study in European Urology titled “The Spread of Misinformation and Bias About Prostate Cancer on YouTube” found that among the first 150 videos on YouTube about prostate cancer, roughly 77 percent contained misleading or biased content, collectively amassing more than six million views. The findings highlight the widespread nature of inaccurate information and its potential impact on patients.

Another study, “Instagram and Prostate Cancer: Using Verification Tools to Assess Social Media Information Quality,” published in Prostate Cancer and Prostatic Diseases, analyzed 126 posts tagged #prostatecancer. About 90 percent were rated low to moderate in quality, and 40 percent of posts with factual information contained major errors or misleading claims. Only around 9 percent of the posts were created by certified medical specialists.

A 2022 study in BJUI Compass, “Accuracy of Prostate Cancer Screening Recommendations for High-Risk Groups on YouTube and TikTok,” found that 98 percent of YouTube videos and 100 percent of TikTok videos about prostate cancer screening were low to moderate in quality and contained moderate to high levels of misinformation. The findings underscore the urgent need for reliable, expert-approved medical content on social media.
