A viral post by nutritionist Debora Rasio has sparked widespread controversy over claims that increased sun exposure protects against melanoma while sunscreen increases the risk of skin cancers. The post, published on Facebook and later blocked due to being labeled as containing "false information" by independent fact-checkers, has generated over 621,842 views, 1,670 comments, and more than 12,000 likes. Rasio, a researcher at Rome’s University of Sapienza and author of several books, cited data from the UK Biobank study published in November 2023 in Cancer Epidemiology, Biomarkers & Prevention. She argued that prolonged sun exposure could offer protection against melanoma, while sunscreen might increase the risk of all types of skin tumors. The reaction was immediate and intense. Dermatologists, oncologists, and public health officials have condemned the post as misleading and dangerous. The Federation of General Practitioners stated that the data cited by Rasio were interpreted selectively and out of context, contradicting established scientific literature. According to Pier Luigi Bartoletti, vice secretary of the federation, the findings "contradict consolidated scientific literature." He referenced a study by the International Agency for Research on Cancer (IARC), which attributes 80% of melanomas globally—267,000 out of 332,000 cases in 2022—to ultraviolet (UV) radiation exposure. UV rays penetrate skin cells, causing genetic mutations, with sunburns doubling the risk of developing melanoma, especially if sustained during childhood. The federation emphasized that up to 45% of melanoma-related deaths could be prevented through proper precautions. The Italian Society of Dermatology (SIDEMAST) echoed similar concerns, stating that excessive and improper sun exposure is the primary risk factor for skin cancer. It urged the correct application of authorized sunscreens, which are designed to act on the surface without penetrating deeper layers or causing systemic absorption. The National Institute of Health (ISS) also dismissed Rasio's claims as misinformation, asserting that sunscreens are not harmful and are not carcinogenic. It stressed the importance of verifying sources and following scientifically validated guidelines to protect public health. The backlash extended beyond medical professionals. On social media, many users began challenging Rasio’s assertions, demanding evidence and defending scientific consensus. Paolo Ascierto, a renowned oncologist and president of the Melanoma Foundation, expressed alarm over the spread of distorted health messages. He called for clarity and warned against the proliferation of misinformation online. Ascierto pointed to the AIOM (Italian Association of Medical Oncology) guidelines, which confirm that UV radiation causes DNA damage leading to skin cancer. He highlighted that sunburns significantly elevate melanoma risk, particularly when occurring early in life. He also refuted the claim that sunscreens are harmful, noting that broad-spectrum SPF 30 or higher provides essential protection. While disappointed by the situation, he noted a positive trend: many users were actively debunking the myths and supporting science. Rasio herself responded to the growing criticism by redirecting followers to a YouTube video for further clarification and offering detailed reports upon request. Despite the controversy, she maintains her stance, arguing that regular sun exposure can reduce melanoma risk by up to 40–50% compared to individuals who remain indoors most of the time. She also suggests that low overall sun exposure correlates with increased melanoma risk. In response, she recommends using high-quality sunscreens free from potentially harmful ingredients such as silicones, parabens, fragrances, oxybenzone, and octinoxate. She advocates for protective clothing, shade, avoiding peak sunlight hours, and adequate hydration. She also emphasizes the importance of activating vitamin D, which she claims may be inhibited by overly heavy sunscreens. The debate continues to unfold, with public health authorities and medical experts reinforcing the need for accurate, evidence-based communication about sun safety. As the discussion evolves, one key takeaway remains clear: protecting skin from UV radiation remains a critical component of preventing skin cancer, and this message must be communicated with precision and care.

The video, based on a study published in 2023, has sparked significant debate. While Rasio's claims have been labeled as containing 'false information' by fact-checkers and led to her video being removed from platforms like Facebook and Instagram, she responded by redirecting followers to a YouTube clarification and providing the study report. Medical associations such as the Federation of General Practitioners and the International Agency for Research on Cancer have criticized Rasio’s interpretation as selective and out of context, emphasizing that UV radiation remains a major cause of skin cancer. The Italian Society of Dermatology and the ISS have also refuted Rasio’s claims, stating that sunscreens are safe and effective when used properly.

OpenIndependentCenter4 hr. agoRapper Salmo has shared a personal account of developing skin cancer, which he attributes to his use of sunscreen creams. He revealed a scar on his temple from surgery to remove a basal cell carcinoma, which has since recurred. His comments sparked debate, referencing claims by nutritionist and oncology specialist Debora Rasio, who suggested increased sun exposure might reduce melanoma risk while sunscreen could increase skin cancer risk. These claims were strongly disputed by the Italian Society of Dermatology and Sexually Transmitted Diseases, which criticized her for misinterpreting study data. The International Agency for Research on Cancer states that UV radiation remains the leading cause of skin cancers, including melanoma and basal cell carcinoma. Current guidelines emphasize avoiding excessive sun exposure, wearing protective clothing, and using sunscreen correctly. The Italian Association for Cancer Research (AIRC) confirms that approved sunscreens are regulated and considered safe based on available evidence, though they do not offer complete protection and should not be used to prolong sun exposure.

Il Fatto QuotidianoIndependentProgressive7 hr. ago "Unfortunately, I, like many others, have put on sunscreen, and the result is skin cancer. Basal cell carcinoma".Salmo, un rapper sardo, ha condiviso un video sui suoi social in cui racconta la sua esperienza personale con il cancro della pelle, specificamente un carcinoma basocellulare. Nella registrazione, Salmo menziona aver utilizzato creme solari e attribuisce il suo cancro alla loro applicazione, anche se non specifica se le creme fossero state utilizzate correttamente o in quantità eccessive. L'articolo fa riferimento a un dibattito online tra l'opinione pubblica e la dottoressa Debora Rasio, oncologa e nutrizionista, che sostiene che l'esposizione al sole possa proteggere dal melanoma, mentre le creme solari potrebbero aumentare il rischio di alcuni tipi di tumore cutaneo. Rasio cita uno studio dell'UK Biobank del 2023 per supportare le sue affermazioni. Salmo sembra essere influenzato dalle opinioni espresse nella videoconferenza di Rasio, pur senza approvare completamente le sue conclusioni.
