SPF 30 Reduces Risk of Melanoma
January 24, 2017
Melanoma is one of the most deadly types of skin cancer. It can be triggered by the ultraviolet rays from the sun, but researchers say we shouldn’t undermine the power of sunscreen. Melanoma is caused by cancer cells in the melanocytes – which are the pigment responsible for skin color, hair and our eyes. They usually take the form of a mole before developing into a full blown cancer.
In a recent clinical study initiated by the Ohio State University Comprehensive Cancer Center to identify methods to prevent melanoma led by Christin Burd, using genetically engineered mice it was proven that using a sunscreen with SPF 30 can lessen the effect of ultraviolet rays to the skin and prevent melanoma.
Their study was discussed during the recent American Association for Cancer Research (AACR). “Over the past 40 years, the melanoma incidence rate has consistently increased in the United States,” Burd said in an interview.
They said sunscreens are known to prevent sunburns but there are no studies to prove if sunscreen with SPF 30 can actually prevent melanoma. Fox News reported that dermatologists have long been vouching for the efficacy of sunscreen, and today even scientists believe in how powerful it is. That’s why they decided to conduct a study on the link between sunscreen and melanoma.
“We have developed a mouse model that allows us to test the ability of a sunscreen to not only prevent burns but also to prevent melanoma…We hope that this model will lead to breakthroughs in melanoma prevention.” Burd said.
Although it is still difficult to identify the efficacy of different sunscreen SPFs, scientists confirm that sunscreen does delay skin cancer or melanoma in genetically engineered mice. But this has to be confirmed if applicable to humans. The scientists who confirmed the study said that there are various factors which can result to a different reaction to humans. For example, the rate and intensity of UVB is different from what they’re using for testing as compared to the UV rays people are exposed to.
Nevertheless, it is enough reason to convince everyone who hasn’t been wearing sunscreen; it’s time to do so now.
