Blind to the burn: Misconceptions about skin cancer risk in the US

Researchers investigate skin cancer risk perceptions and sun-protective behaviors in adults

Blind to the burn: Misconceptions about skin cancer risk in the US
2025-03-12
(Press-News.org) Skin cancer is the most common cancer in the United States and a significant health issue, with millions of non-melanoma cases and tens of thousands of melanomas diagnosed annually. Furthermore, treating skin cancer costs the U.S. approximately $8.9 billion annually.  

Those with fair skin, a history of sun exposure or tanning bed use, and a genetic predisposition, are at higher risk. Key barriers to prevention include a lack of awareness, cultural preferences for tanned skin, and limited access to sun protection.

A study by researchers at Florida Atlantic University’s Charles E. Schmidt College of Medicine is one of a few to explore associations between reported number of sunburns and sociodemographic characteristics, in addition to examining prevalence of protective skin behaviors adopted by the U.S. adult population in a nationally representative sample. According to the American Academy of Dermatology, experiencing five or more blistering sunburns between ages 15 and 20 increases one’s melanoma risk by 80% and nonmelanoma skin cancer risk by 68%.

Using data from the U.S. National Cancer Institute’s 2022 Health Information National Trends Survey 6 (HINTS 6), researchers selected questions focused on respondents’ confidence in their health, perceived cancer risk, and worry about getting diagnosed with cancer, as well as their sunburn experiences over the past year. Sociodemographic factors that were studied included age, gender, occupational status, marital status, educational level, Hispanic origin, race and income due to their potential link to skin cancer risk.

Among 6,252 participants surveyed, when asked how confident they felt about their ability to take good care of their own health, most respondents felt either very confident (44%) or completely confident (27.3%). Findings, published in the American Journal of Lifestyle Medicine, also showed most respondents had moderate concerns about skin cancer risk. Only 9.1% reported being extremely worried, while the majority were either somewhat (26.6%) or slightly (25.6%) concerned.

For sunburn and skin protection, 67.6% reported no sunburns in the past year, while 30.3% had 1-5 sunburns. Additionally, 6.4% reported consuming alcohol while sunburned, a known risk factor for increased sunburn incidence. Activities like drinking alcohol, working outside or swimming were common among those who reported sunburns.

Using multinomial regression analysis, statistically significant associations were reported between the number of sunburns and sociodemographic factors. Adults (over 40) had lower sunburn risks, as did women. Disabled, unemployed, and multi-occupation participants reported fewer sunburns. Married or partnered individuals had higher risks of sunburn, while divorced or single participants had lower risks. Higher education levels, being Hispanic, Black, Asian or of mixed race were linked to lower sunburn risks. Higher income groups had significantly higher risks of sunburns, with the highest income group being more than four times more likely to report a sunburn. 

“Social determinants such as race/ethnicity, sex, income and employment status are closely linked to sunburn and skin cancer risk,” said Lea Sacca, Ph.D., senior author and an assistant professor in the Department of Population Health and Social Medicine, within the Schmidt College of Medicine. “While Hispanics and Black Americans generally report lower rates of sunburn, Hispanics often perceive greater benefits of UV exposure, which increases their risk. Factors such as sex, education, and income also influence sunscreen use, with lower use observed among Black Americans and Hispanic Americans. However, within these groups, women with higher education and income are more likely to use sunscreen. Interestingly, higher income is associated with more frequent sunburns.”

Skin cancer includes three main types: basal cell carcinoma, squamous cell carcinoma and melanoma. Basal cell carcinoma is the most common and least aggressive, typically appearing as a shiny, pearly bump or pinkish patch, often on sun-exposed areas. Squamous cell carcinoma usually appears as red, scaly patches or open sores and can spread to other parts of the body if not treated early. Melanoma, the most dangerous form, develops in pigment-producing cells (melanocytes) and can appear as a new mole or changes to an existing one. It is highly aggressive and can spread quickly to other organs if not caught early.

“Understanding perceptions of skin cancer risk and the prevalence of protective behaviors is vital to reducing the likelihood of developing skin cancer, particularly among vulnerable groups,” said Madison Etzel, first author and a second-year medical student in the Schmidt College of Medicine. “Our study underscores the importance of raising awareness about skin cancer susceptibility as we found that all sociodemographic factors were significantly linked to the number of reported sunburns in the past year. Future research should explore how additional social determinants of health influence sunburn incidence and prevention behaviors. A deeper understanding of these factors is critical to addressing the widespread harms of skin cancer in U.S. adults.”

According to the American Cancer Society and other health organizations, practicing sun safety and skin awareness is vital to preventing skin cancer. Regularly applying a broad-spectrum sunscreen with an SPF of 30 or higher, especially when spending time outdoors, and reapplying every two hours is essential as a first step for skin cancer prevention. Avoiding direct sunlight, particularly between 10 a.m. and 4 p.m., when UV rays are strongest, and seeking shade whenever possible are also additional preventive strategies to consider to reduce the risk of this disease. Moreover, protecting skin further by wearing long-sleeve clothing, wide-brimmed hats and sunglasses with 100% UVA/UVB protection has also been recommended. It’s also crucial to avoid tanning beds, as they increase the risk of skin cancer.

Regular self-exams of the skin for any unusual moles or changes, along with professional skin screenings by a dermatologist, can help with early detection. Surfaces like water, sand and snow also can reflect UV rays, so reapply sunscreen more frequently in these environments. Finally, staying hydrated supports skin health and resilience against UV damage.

Targeted alpha therapy: a breakthrough in treating refractory skin cancer

Targeted alpha therapy: a breakthrough in treating refractory skin cancer
2025-03-12
Metastatic melanoma, also known as stage IV melanoma, is a type of skin cancer that spreads to other parts of the body. It is one of the most aggressive forms of skin cancer, with current therapies—including immunotherapy and targeted drugs—showing limited effectiveness. Radiotherapy is an emerging treatment for melanoma, but conventional beta-emitting radionuclide therapies have limitations due to their low energy transfer and long-range radiation, which can cause unintended damage to healthy tissues. To enhance the efficacy of radiotherapy, a research team from Japan, led by Assistant Professor Hiroyuki Suzuki ...

Transforming thymic carcinoma treatment with a dual approach

Transforming thymic carcinoma treatment with a dual approach
2025-03-12
Thymic epithelial tumors are a rare group of malignancies originating in the thymus gland, that includes thymoma and thymic carcinoma. Among these, thymic carcinoma is the more aggressive subtype, characterized by high invasiveness, metastatic potential, and poor prognosis. With an incidence of just 0.15 cases per 100,000 person-years, its rarity poses significant challenges for treatment development. While platinum-based chemotherapy remains the current standard of care, its efficacy is limited. Immune checkpoint inhibitors have shown promise in pretreated cases, but durable ...

Wrong on skin cares: keratinocytes, not fibroblasts, make collagen for healthy skin

Wrong on skin cares: keratinocytes, not fibroblasts, make collagen for healthy skin
2025-03-12
The skin consists of two primary layers. The epidermis, the outermost layer, is predominantly made up of keratinocytes, while the deeper dermis contains blood vessels, nerves, and structural proteins such as collagen, which give the skin its strength and texture. Traditionally, fibroblasts—specialized supporting cells within the dermis—have been believed to play a key role in producing collagen. In humans, collagen is formed before and after birth. It has been believed that fibroblasts play an exclusive role in collagen production in the skin, and no keratinocytes contribute to collagen production. The statement “Collagen production in the human skin is achieved by fibroblasts” ...

Delhi air pollution worse than expected as water vapour skews figures

2025-03-12
New Delhi's air pollution is more severe than previously estimated with particles absorbing atmospheric water vapour leading to particulate matter levels across the city being underestimated by up to 20%, a new study reveals.  Hygroscopic growth causes fine particulate matter (PM1) to swell, reducing sampling devices efficiency and leading to underestimation, with greatest underestimation in estimated concentrations happening during winter morning rush hours, when humidity is highest and pollution is most severe.   In contrast, research shows that the monsoon ...

First radio pulses traced to dead-star binary

First radio pulses traced to dead-star binary
2025-03-12
An international team of astronomers, including a Northwestern University astrophysicist, has traced a series of mysterious radio pulses to an unprecedented home. Starting a decade ago, astronomers have detected a pulse of radio emission every two hours, coming from the direction of the Big Dipper. After combining observations from multiple telescopes, the team can now reveal the culprit: a binary system with a dead star. According to the new study, a red dwarf and white dwarf are orbiting each other so tightly that their magnetic fields interact. Each time they bump together — which is every two hours — the interaction emits a long radio blast. Although astronomers ...

Entwined dwarf stars reveal their location thanks to repeated radio bursts
2025-03-12
An international team of astronomers led by Dr Iris de Ruiter, now at the University of Sydney, has shown that a white dwarf and a red dwarf star orbiting each other every two hours are emitting radio pulses. Thanks to follow-up observations using optical and x-ray telescopes, the researchers were able to determine the origin of these pulses with certainty. The findings explain the source of such radio emissions found across the Milky Way galaxy for the first time. The results are published in Nature Astronomy. In recent years, better analysis techniques have given researchers the ability ...
