We Need More Research on Sun Protection:
A research review concludes, there isn’t much evidence to conclusively prove that daily sunscreen use can prevent most skin cancer. The doctors say, that doesn’t mean we shouldn’t use sunscreen. It just means it’s unethical to do experiments testing the effectiveness of sunscreen. First of all you would have to randomly assign people to use sunscreen and others to skip it. In addition, there is a lack of high quality experimental evidence. Therefore we should not rule out sunscreen as ineffective. As a result, it is important that patients and consumers do not stop protecting their skin with sun protection. Until evidence emerges, sun protection like sunscreen should be used to deter skin cancer. Melanoma is a seriouse issue.
Measuring the Effect of Sun Protection:
In the research review, doctors pointed out that it’s difficult to measure the effect of sun protection. Most noteworthy, it is not ethical or practical to randomize the population on the prevention of skin cancer. For example, you would have to tell one group to seek shade, wear a hat, and use sunscreen. In addition, you would have to tell another to sit in the direct sun and abstain from use of sunscreen. Lack of evidence does not mean that sun protection has no impact on the risk of skin cancer. The impact from sun protection can be difficult to measure in the research for skin cancer or melanoma.
Looking For Clues:
In a review published by the Cochrane Library, colleagues set out to assess what we already know about sun protection. Therefore, they assessed whether sunscreen, wearing hats or sunglasses or staying in the shade, prevent skin cancer. Furthermore, in the research colleagues focused on what’s known as basal cell and cutaneous squamous cell carcinomas. As a result these ailments make up the majority of skin cancer cases. In the research review, their analysis didn’t look at melanoma, a rare and much more deadly type of skin cancer.
A Study in Australia:
The research team only wanted to look at trials that randomly assigned some people to use sunscreen or other protection. In the research trials they found just one study that met their criteria. Most noteworthy, a study done in Australia monitored about 1,600 people for more than four years. In the research Australia didn’t find a meaningful difference in the number of new cancer cases detected. That might not be long enough to follow patients to see if sunscreen prevents skin cancer and melanoma. It can take several years after sun exposure to detect abnormalities on the skin.
What this does suggest is that more high-quality research is needed, the authors told Reuters Health. In conclusion, patients and consumers need to obtain specific advice about the need of sun protection or sunscreen. Age, skin color, occupation and presence of other risk factors of skin cancer and melanoma should be in the research. As a result, there’s already plenty of proof that exposure to ultraviolet rays causes skin cancer and melanoma. A skin cancer researcher at Yale School of Medicine agreed, but the researcher wasn’t involved in the research review.
According to the research review, regular use of sun protection reduces skin cancer and cancer precursors which is most noteworthy. 60% of melanoma or skin cancer should inspire the benefits of sun protection. In addition, the evidence of sunburn and chronic sun exposure fit into the moderate to high risk groups of skin cancer.
