ImpactHigh impact

Participants recognize the potential significance of the research in influencing sunscreen usage behavior and public health messaging around skin cancer prevention.

Abstract in brief

  • A randomized trial in Queensland, Australia investigated whether regular sunscreen use reduces the risk of cutaneous melanoma over time.
  • After 10 years, 11 new melanomas were found in the daily sunscreen group compared to 22 in the discretionary group, indicating a potential reduction in melanoma rates.
  • The data suggested that using sunscreen daily could lead to a significant decrease in invasive melanoma cases, supporting the notion that melanoma may be preventable with consistent sunscreen application.

Er blijkt slechts één RCT te vinden te zijn: https://t.co/rJmdSh6sPC Dat is niet verbazingwekkend, want preventieve effecten onderzoeken is uiterst lastig met RCT's. Bovendien wordt het geven v placebo als onethisch gezien, dus worden dergelijke studies niet goedgekeurd. 4/16

Sunlight is everywhere, sunscreen only cuts melanoma risk by ~50% & not everyone uses it correctly. We still use it. Importantly, carcinogenesis is stochastic & delayed. Most smokers don’t get lung cancer & not all lung cancer patients were smokers. (10/) https://t.co/xqNGUUCG1h

Here is the only prospective trial to study whether sunscreen reduced incidence of melanoma. The absolute risk reduction is ~1% (meaning 100 people would have to apply regularly to avoid 1 melanoma), and the result was of “borderline” significance: https://t.co/DgF46wxfi6 https://t.co/a3VyzK9FON

@xCryptoKennedy @Get_Schwifty93 @Crdn0Dd1 @Tradermayne Misses out a key point however. People who wear suncream regularly will be those who live in sunnier, hotter places and therefore exposed to increased amounts of sunlight, leading to higher chances of cancers. This is also a single study. https://t.co/SZNdwwKXSo read this.

@juleslipoff Its a case control study with the problem of recall bias, particularly in Australia where skin cancer awareness is HUGE. You can imagine people with melanoma over-reporting sun exposure. The ONLY RCT is this one, also from Australia: https://t.co/DgF46wxfi6
