Sun Damage Lasts a Lifetime

Sun ProtectionAfter a long, rough winter, it feels good to put away the jackets and get out the swim gear. As a melanoma oncologist, the summer is a double-edged sword as it also means that many people will be out in the sun doing irreversible damage to their skin. Not only can sun safety decrease your risk of skin cancer, it also can help protect you from the visible signs of aging. Who doesn’t want less cancer and to look younger at the same time? Unfortunately, some people believe they need a good burn or base tan to start the summer. Hopefully, I can change your mind about this with some basic information about skin cancer and a few tips on enjoying the summer without increasing your risk of developing skin cancer (or more wrinkles).

Skin cancer affects over three million people each year, making it by far, the most common cancer. The three most common skin cancers are basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal and squamous cell cancers are the most prevalent and originate from keratinocytes. These cancers are often referred to as “non-melanoma skin cancers.” They affect a little over two million Americans each year, with 80 percent of these being basal cell cancers. Most non-melanoma skin cancers are caused by repeated exposure of the skin to ultraviolet rays (primarily UVA and UVB) from sunlight or from artificial sources such as tanning beds. These rays damage the DNA in skin cells and cause them to grow and divide unregulated, thus producing a cancer. These types of skin cancers tend to stay in the skin, and therefore very few patients will die from basal or squamous cell cancers. It is estimated that approximately 2,000 people die each year from non-melanoma skin cancers.

In contrast, melanoma is a cancer that originates from melanocytes that normally make pigment to protect the other layers of the skin from sun damage. Melanocytes can also make non-cancerous growths like moles. The American Cancer Society estimates approximately 76,100 new melanomas will be diagnosed in 2014 with 9,710 deaths from this disease, making it the most deadly form of skin cancer. Lifetime risk of melanoma in the U.S. is about 1 in 50, and notably it is one of the most common cancers in those younger than 30. When diagnosed early, surgery alone has excellent survival rates. In the past there were few long-term survivors from advanced cases of melanoma. Fortunately, many novel therapeutic agents are being developed that have transformed the treatment of more advanced stages of melanoma with five new agents approved by the FDA since 2011. All of these new drugs are changing the landscape of melanoma treatment and patients are now not only living longer, but also with better quality of life.

Though melanoma development is more multi-factorial than basal or squamous cell cancer development, it is still linked to UV exposure through sunlight or tanning beds. The best way to decrease one’s risk of skin cancer development is to avoid long exposures to intense sunlight and practice sun safety measures. When outside, I recommend the use of broad spectrum sunscreen (SPF 30 or higher), use of sun protective clothing such as sun shirts and board brim hats, and avoid direct exposure between 10AM and 2PM when the intensity of the rays is the strongest. Sunscreen should be applied about 20-30 minutes prior to going outside and reapplied approximately every two hours. Because this is difficult to do, even for myself, I recommend barriers like sun shirts or umbrellas over sunscreen if possible.

Keep in mind the sun damage that occurs now will be with you for the rest of your life, so please don’t forget your sun protective gear on your way out to enjoy the beautiful weather.

Take action now to avoid detrimental long term effects from the sun.You can read a full transcript of the Skin Cancer and Melanoma chat here.

When do your Moles Require a Trip to the Dermatologist?

Skin Cancer MolesHave you performed your monthly mole check? If not, take time today to do it and put it on your calendar for this day every month! Checking your moles monthly can help you from developing malignant melanoma. The earlier you find suspicious moles or lesions, the better your chances of being cured.

Some helpful tips to examine your moles:

  • Examine your skin after a shower, in good light, in front of a mirror without your clothes on.
  • Make sure to do a thorough, full body inspection. Start with your toes or your face and work your way over every surface of your body. Be sure to also check your scalp, underarms and genitals, parts that could be covered with hair.
  • Look for moles or skin markings that you haven’t noticed before, or areas that have changed in appearance since your last exam. Pay special attention to lesions that bleed or don’t heal.
  • Photos taken over a period of time can be helpful in determining whether a skin marking has changed.
  • Follow the ABC method for examining suspicious markings:
    • A = Asymmetry – do both sides of the mole match? If one side does not match the other, it could indicate melanoma.
    • B= Border – If the border has jagged or irregular edges, see your physician right away.
    • C = Color – Black, red, white and multi-colored moles should be seen by a professional right away. Tan and brown moles are usually ok, but make sure to watch for changes to these moles as well.
  • Diameter – Usually moles should be smaller than the end of a pen.
  • Elevation – moles should be flush with the skin around the mole. If you notice a mole is raised, visit your physician right away.
  • Do what you can to prevent skin cancer. Some ideas:
  • Wear sunscreen in the sun, in all seasons!
  • Wear a hat and sunglasses
  • Avoid tanning salons
  • Try to stay out of the sun between 10am and 3pm

Skin Cancer Online ChatIf not caught early, melanoma is the deadliest of all skin cancers. One-in-fifty Americans has a lifetime risk of developing melanoma. It develops from changes to the DNA of skin cells, which can happen when skin is over-exposured to ultraviolet light from the sun or from extended tanning bed use. Also, certain viruses can cause DNA changes that lead to skin cancer.

To prepare yourself and your family for the summer and protect yourself from any form of skin cancer, join Winship Cancer Institute of Emory University physician, Keith Delman, MD, Wednesday, May 29th for an online web chat at 12 noon.
