It’s time for your skin check!
Skin Cancer is the most common cancer, with more people diagnosed in the U. S. annually than all other cancers combined. About 90% of nonmelanoma skin cancers and approximately 86% of melanomas are related to UV radiation (sun exposure or tanning beds). For people who have experienced 5 or more sunburns, their risk of melanoma doubles.
So what can you do? May is National Skin Care Awareness month, and a chance to brush up on sun safety precautions in time for summer sunshine, and warmer, longer days. Obviously, sun avoidance is the safest bet, but likely not a reality for most. Here are some guidelines to help you enjoy the outdoors safely this season.
Wearing a sunblock with an SPF factor of 30 or higher that provides a broad-spectrum protection (blocks both UVA and UVB rays) and preferably water-resistant is the best choice for adequate sun protection. It is also important to reapply sunblock every 2 hours when outdoors, and also while swimming, exercising or when using a towel to dry the skin or remove sweat. UV rays penetrate even through cloudy and gloomy weather, so it is essential to reapply sunblock even if it’s not hot outside.
Sunscreen vs. Sunblock? What is the difference? Sunscreens contain chemical agents such as oxybenzone and octinoxate that penetrate into the skin and absorb the light rays, creating and releasing heat as a result. Sunblocks on the other hand contain a mineral ingredient such as titanium dioxide or zinc oxide that acts as a physical barrier and blocks and reflects the sun’s rays from penetrating into the skin. Most sunblocks containing zinc or titanium are also considered “reef friendly” and safer for marine environments.
Additional preventative measures include:
Limiting direct sun exposure between the hours of 10 am to 4 pm
Wearing sun protective clothing
Take breaks in the shade
Wearing a wide brim hat to provide shade for your face, neck and ears
Opting for sunglasses with UVA and UVB protection
Additionally, an early diagnosis and treatment of skin cancer may allow for a more minimally invasive treatment with a higher chance for successful treatment. Annual skin exams are key to early diagnosis, and will include a full skin and scalp check, especially if you have any atypical or new moles. Prior to the exam you should remove make up and nail polish and wear your hair loose to allow for a full exam.
