How Online Misinformation Is Undermining Skin Cancer Prevention
By: Jeff Yorio, M.D., Texas Oncology-Austin Central
Summer in Texas means longer days,
backyard barbecues, afternoons at the pool and weekends spent outside. While
most people are focused on staying cool and hydrated, there is another summer
health risk right at our fingertips: misinformation spreading online.
Social media has become a place where
health advice travels fast, but not all of it is accurate. In recent months, viral
posts questioning the safety and effectiveness of sunscreen have gained
traction across social media platforms. Although these claims often attract
attention, they can also discourage people from taking one of the simplest and
most effective steps towards reducing their risk of skin cancer.
The impact is already showing.
According to a recent survey from the American Academy of Dermatology, more
than 16 million American adults say they have reduced or stopped using
sunscreen because of claims they encountered online. Nearly half of Americans
report seeing sunscreen misinformation, with younger adults being exposed at
even higher rates.
As an oncologist who treats patients
with melanoma and other cancers, I've seen firsthand how devastating a skin
cancer diagnosis can be. Many people are surprised to learn that skin cancer is
the most common cancer in the United States. The good news is that many cases
are preventable, making simple, evidence-based prevention even more critical.
One of the most common myths
circulating online is that sunscreen is unnecessary, ineffective or somehow
more harmful than sun exposure itself. The scientific evidence tells a
different story. Ultraviolet (UV) radiation damages skin cells, accelerates premature
aging and significantly increases the risk of developing skin cancer.
Broad-spectrum sunscreen has been studied extensively and remains a safe,
effective way to help protect your skin when used as directed.
Sun damage also adds up over time.
Even just a few blistering sunburns during childhood or adolescence can
significantly increase a person's risk of developing melanoma later in life.
That's why sun protection isn't just something to think about while on vacation
or during a day at the lake, it's a healthy habit worth practicing every single
day, whether you're walking the dog, working in the yard or simply running
errands.
Protecting your skin doesn't have to
be complicated. Wear broad-spectrum sunscreen with an SPF of at least 30, re-apply
every two hours when spending time outdoors, seek shade during peak sunlight
hours (10 a.m. to 3 p.m.) and wear protective clothing, a wide-brimmed hat and
sunglasses whenever possible.
When it comes to your health, social
media should never replace medical expertise. If you have questions about
sunscreen or your skin cancer risk, talk with your healthcare provider and rely
on trusted, evidence-based sources for guidance. It's understandable why people have questions
when they're exposed to conflicting messages every day. Asking those questions
is healthy. The key is making sure the answers come from sources grounded in
evidence rather than algorithms designed to maximize clicks and engagement.
That's where the relationship
between patients and their healthcare providers matters most. Physicians have a
responsibility not only to diagnose and treat disease, but also to help
patients understand the science behind the recommendations we make. Those
conversations build trust, and trust is essential to helping people make
informed decisions about their health.
