How to Protect Yourself During National Skin Cancer Awareness Month

Did you know May is National Skin Cancer Awareness Month? With warm weather here, it’s hard to not want to spend time in the sun. Being out in the sun makes our skin glow and everyone a little happier. It can also make us forget the threats that are associated with spending too much time in its’ rays. Skin cancer is the most common form of cancer in the United States. It often goes undetected until it’s too late. Here is everything you need to know about protecting yourself while you enjoy the summer months:

UV Index:

The three most common forms of skin cancer are caused by overexposure to ultraviolet light. The UV Index ranks exposure levels to ultraviolet light based on a zero to 15 scale. The Centers for Disease Control and Prevention recommends wearing sun protection if the UV Index is a level three or higher. Weather apps calculate the UV Index for when you want to check the ultraviolet levels in your area.

Wear Sunscreen:

This is an obvious one! You should never be out in the sun without some sort of protection. Your sunscreen should have a sun protection factor (SPF) of 15 or higher. It should also be broad spectrum to protect you from both UVA and UVB rays. Sunscreen should be reapplied every two hours or after swimming, sweating and toweling off. Check the expiration date on the bottle to see if it has exceeded its shelf life before using.

Avoid Indoor Tanning:

The use of tanning beds is not safe for your skin and is definitely not recommended. One session in the tanning bed increases the risk of developing melanoma by 20 percent. A tan is the body’s response to injury from UV rays, so even getting a base tan is harmful to your skin.

Regular Skin Checks:

When detected early, skin cancer is very treatable. Self-examining your skin for suspicious moles can help you catch it before its too late. Observe the places on your body that receive the most sun exposure like your neck, legs, feet, elbows and arms. Ask a friend for help checking those hard-to-see places like your back and scalp.

Tanning Facts – Bed, Bottle or Sun (Part 3)

It’s hard not to associate summer with sunshine and tanning. We all covet that “healthy glow”, but what measures are we willing to take to get it? To make things easier for the tan-lovers out there, your Knoxville Dermatology team put together the facts about bottle, bed and sun tanning. In this entry, we’ll talk about outdoor tanning or sun tanning.

Sun:

We’ve mentioned the differences between UVA and UVB rays before, but let’s go a little more in depth. UVB rays affect your outer most layer of your epidermis (the upper layer of skin) and cause the painful sunburns we all know and love. UVA rays go deeper into the lower layers of your epidermis. They trigger cells called melanocytes to produce melanin, the pigment that causes tanning.

UVA rays may make you tan, but they can also cause serious damage because they penetrate deeper into the skin. UVA rays can go all the way through the skin’s protective epidermis to the dermis, where blood vessels and nerves are found. Because of this, UVA rays may damage your immune system. This makes it harder to fight off diseases and can lead to illnesses like melanoma, the most serious type of skin cancer. Exposure to UVB rays also increases your risk of getting two other types of skin cancer: basal and squamous cell carcinoma.

Cancer isn’t the only problem associated with UV exposure. UV damage is a major proponent of premature skin aging like sunspots, wrinkles and decreases skin elasticity. It can also cause cataracts over time.

The easiest way to avoid all of the consequences of UV damage is prevention. The sun’s peak time is between 10 a.m. and 4 p.m. so be particularly cautious when outdoors in that time period. Wearing sunscreen on your face, neck and arms every day will help prevent premature aging. Also, you should perform annual skin checks at least once a month to make note of any changes in your skin.

Tanning Facts – Bottle, Bed or Sun (Part 2)

It’s hard not to associate summer with sunshine and tanning. We all covet that “healthy glow,” but what measures are we willing to take to get it? To make things easier for the tan-lovers out there, your Knoxville Dermatology team put together the facts about bottle, bed and sun tanning. In this entry, we’ll talk about tanning beds.

Bed:

Don’t be fooled by the tanning bed industry. They’ve fed us all lines about “healthy rays” and getting a “base tan” to keep from burning. But the truth is, tanning is just not a part of living a healthy life – whether it’s by bed or by sun.

Further research has shown us the dangers of tanning beds. Last year, the International Agency for Research on Cancer shifted indoor tanning beds to the highest cancer risk category – “carcinogenic to humans.” They cause users to become more vulnerable to melanoma; your risk increases 75% if used only once before the age of 35. Tanning is equivalent to a sunburn in terms of the effect on your skin, so despite developing a “base tan” or easing into it, you are still causing DNA damage to your skin.

Other consequences of indoor tanning are premature aging and wrinkles. Immune system suppression and eye damage are side effects that have also been linked to indoor tanning.

Now we don’t want to mislead you. We are not saying you should avoid the sun and UV rays at all costs. We’re simply saying you should understand the risks and monitor your sun and UV ray exposure.
