Not all organs are internal. The skin is the largest and contains three layers: the epidermis (outer), dermis (middle), and hypodermis (deepest). When cancer cells affect any of these areas, the situation can potentially be life-threatening. Several factors can raise an individual's risk of developing skin cancer. But the condition is preventable. Minimizing your exposure begins with a visit to the dermatologist. At Dawson Dermatology, you can expect a quick and efficient head-to-toe examination from Dr. Kevin L. Dawson, Dr. Douglas Chun, or Dr. Sarah J. Grekin performed in our Honolulu, HI, office to review family medical history and look for suspicious moles that may need additional testing.

Tips to Prevent Skin Cancer

Skin cancer prevention starts with protection. UV rays that emit from the sun, as well as tanning beds, are harmful, so it's best to avoid both whenever possible. When you're outside, be sure to apply 30-SPF sunscreen and lip balm year-round, wear additional clothing like a brimmed hat and stay in the shade - especially between the hours of 10 a.m. and 4 p.m. when rays are the strongest. It also helps to wear sunglasses, avoid reflective surfaces, and choose cosmetic products that offer sun protection.

Signs and Symptoms to Observe

Different types of skin cancer have distinct traits. We encourage you to visit our Honolulu, HI, office at the first sign of something unusual. If you're unsure of what to look for when performing a physical exam at-home, our dermatologist can teach you how to spot skin damage. At Dawson Dermatology, we always remind our patients to remember their "ABCDE's." This acronym stands for asymmetrical, border, colorful, diameter, and evolving. When a mole or freckle doesn't look like the rest, has an irregular border, color changes, or becomes bigger than a pencil eraser, it may be cause for concern and require extra attention.

If you observe new moles, lesions, or freckles with an "ugly duckling" appearance, or find yourself itching or bleeding, schedule a consultation with our dermatologist. We have a team of board-certified professionals who are dedicated to catching signs and symptoms early when they are most treatable. For more information about skin cancer, other conditions we treat, and services provided at Dawson Dermatology, visit our website. Please call (808) 599-3780 for appointment scheduling with Dr. Kevin L. Dawson, Dr. Douglas Chun, or Dr. Sarah J. Grekin in our Honolulu, HI, office.

During the much longed-for summer months, people work on their tans. While enjoying a richer skin tone now, tanners take huge risks for premature aging and skin cancer. 

Sun and artificial tanning

It's what we use to get those tans. But, did you know that when you tan, you actually burn the top layer (epidermis) of your skin and damage your DNA, too?

According to Live Science, DNA damage mutates normal skin cells into cancer cells. Basal cell and squamous cell carcinomas are the most common kinds of skin cancer. Malignant melanoma is the most deadly skin cancer as it easily metastasizes to major body organs. About one-third of melanoma cases in the US kill their sufferers annually, says The Skin Cancer Foundation.

Unfortunately, artificial tanning is just as dangerous as sitting in the sun. Intermittent sun exposure or occasional tanning in the sun or tanning beds are harmful, too. Damage to the skin is cumulative, and both kinds of ultraviolet radiation (there are UV-A and UV-B rays) breakdown your skin's DNA over time. Further, UV-B harms your skin's natural elasticity normally provided by a protein called collagen.

Don't tan: protect

To protect your skin, avoid sunburns, intentional tanning and excessive day to day sun exposure with these strategies from the American Academy of Dermatology (AAD):

  1. Cover up any exposed skin (face, arms, legs, ears) with a broad-brimmed hat, long-sleeves and other sun-protective clothing.
  2. Use sunscreen lotion--SPF 30 or higher--on all exposed skin, and re-apply every two hours or whenever you sweat it off or swim.
  3. Stay indoors or in the shade from 10 am to 2 pm.

Also, all adults, particularly those 40 or older, should see a dermatologist for an annual skin exam. Do a careful self-exam once a month at home, looking for changes in the color, size, and shape of existing spots or moles. Report changes to your skin doctor as well as any sore which does not heal in a week or so.

It's your skin

Don't sacrifice its health for a little fashionable color. Tanning really is bad for you. Find healthy ways to enjoy the summer months and that wonderful sun. Your skin and your overall health will be better for your efforts.

Skin Cancer PreventionWith the warmer months just around the corner you may be getting ready to plan some fun in the sun. The summertime always finds children spending hours outside playing, as well as beach-filled family vacations, backyard barbeques, and more days just spent soaking up some much-needed vitamin D.

While it can certainly be great for our emotional and mental well-being to go outside, it’s also important that we are protecting our skin against the harmful effects of the sun’s rays. These are some habits to follow all year long to protect against skin cancer,

Wear Sunscreen Daily

Just because the sun isn’t shining doesn’t mean that your skin isn’t being exposed to the harmful UVA and UVB rays. The sun’s rays have the ability to penetrate through clouds. So it’s important that you generously apply sunscreen to the body and face about 30 minutes before going outside.

Opt for a broad-spectrum sunscreen with an SPF of at least 30 that also protects against both UVA and UVB rays. Everyone should use sunscreen, even infants. Just one sunburn during your lifetime can greatly increase your risk for developing skin cancer, so always remember to lather up!

Reapply Sunscreen Often

If you are planning to be outdoors for a few hours you’ll want to bring your sunscreen with you. After all, one application won’t be enough to protect you all day long. A good rule of the thumb to follow is, reapply sunscreen every two hours. Of course, you’ll also want to apply sunscreen even sooner if you’ve just spent time swimming or if you’ve been sweating a lot (e.g. running a race or playing outdoor sports).

Seek Shade During the Day

While feeling the warm rays of the sun on your shoulders can certainly feel nice, the sun’s rays are at their most powerful and most dangerous during the hours of 10am-4pm. If you plan to be outdoors during these times it’s best to seek shady spots. This means enjoying lunch outside while under a wide awning or sitting on the beach under an umbrella. Even these simple measures can reduce your risk for skin cancer.

See a Dermatologist

Regardless of whether you are fair skinned, have a family history of skin cancer or you don’t have any risk factors, it’s important that everyone visit their dermatologist at least once a year for a comprehensive skin cancer screening. This physical examination will allow our skin doctor to be able to examine every growth and mole from head to toe to look for any early signs of cancer. These screenings can help us catch skin cancer early on when it’s treatable.

Noticing changes in one of your moles? Need to schedule your next annual skin cancer screening? If so, a dermatologist will be able to provide you with the proper care you need to prevent, diagnose and treat both melanoma and non-melanoma skin cancers.

Sun DamageToo much exposure to sunlight can be harmful to your skin. Dangerous ultraviolet B (UVB) and ultraviolet A (UVA) rays damage skin, which leads to premature wrinkles, skin cancer and other skin problems. People with excessive exposure to UV radiation are at greater risk for skin cancer than those who take careful precautions to protect their skin from the sun.

Sun Exposure Linked to Cancer

Sun exposure is the most preventable risk factor for all skin cancers, including melanoma. To limit your exposure to UV rays, follow these easy steps.

  • Avoid the mid-day sun, as the sun's rays are most intense during 10 a.m. and 4 p.m. Remember that clouds do not block UV rays.
  • Use extra caution near water, snow and sand.
  • Avoid tanning beds and sun lamps which emit UVA and UVB rays.
  • Wear hats and protective clothing when possible to minimize your body's exposure to the sun.
  • Generously apply a broad-spectrum, water-resistant sunscreen with a Sun Protection Factor (SPF) of at least 30 to your exposed skin. Re-apply every two hours and after swimming or sweating.
  • Wear sunglasses to protect your eyes and area around your eyes.

Risks Factors

Everyone's skin can be affected by UV rays. People with fair skin run a higher risk of sunburns. Aside from skin tone, factors that may increase your risk for sun damage and skin cancer include:

  • Previously treated for cancer
  • Family history of skin cancer
  • Several moles
  • Freckles
  • Typically burn before tanning
  • Blond, red or light brown hair

If you detect unusual moles, spots or changes in your skin, or if your skin easily bleeds, make an appointment with our practice. Changes in your skin may be a sign of skin cancer. With early detection from your dermatologist, skin cancers have a high cure rate and response to treatment. Additionally, if you want to reduce signs of aged skin, seek the advice of your dermatologist for a variety of skin-rejuvenating treatment options.

Skin CareWhen school is in session, it’s easy for students to pick up a number of bad habits between late nights of studying and long sports practices. From poor eating habits to a lack of sleep and increased stress, unhealthy lifestyles can lead to unhealthy skin.

Whether you’re in middle school, high school or college, students everywhere can benefit from healthier skin. With a little extra care and attention, you can keep your skin blemish free all year long.

Keep your skin clean

This may sound obvious, but keeping your face clean is one of the most important things you can do to improve its health. Get in the habit of washing your face twice a day with warm water and a mild soap to remove the dirt and debris that accumulate throughout the school day.  

Hands off!

Avoid touching your face with your hands throughout the day as your hands contain oils that cause breakouts. Never pop pimples as this can irritate the skin, make acne worse and increase your risk for scarring.      

Moisturize

Moisturizers seal moisture into the skin to prevent skin from drying out. Your dermatologist can help you determine the best moisturizer for your skin type.

Avoid excessive sun exposure

Protect your skin from the sun by wearing sunscreen and avoiding overexposure. Too much sun can damage the skin leading to future breakouts and even skin cancer.

Improve your physical well-being

Your skin reflects what you eat, so remember to eat a balanced diet rich in vitamins and antioxidants. Learn to manage stress as it can make your skin more sensitive and trigger acne breakouts and other skin problems. Get plenty of rest every night; approximately 7-8 hours of restful sleep is essential for healthy skin.

By maintaining a consistent daily regimen that includes washing and a healthy diet, you can achieve clear, healthy skin throughout the entire school year. Whenever you have a question or concern about your skin, talk to your dermatologist. Dermatologists offer a range of treatments that help prevent and treat acne and other skin conditions. We can help you find the treatment method that's best for you.
