Consult a dermatologist promptly if any changes are observed.

 

Can melanoma spread? Is it dangerous?

Mohs micrographic surgery is a precise technique for removing skin cancer that helps preserve healthy tissue. Other techniques for treating skin cancer include curettage and electrosurgery, cryosurgery, radiation, photodynamic therapy, laser surgery, and topical medications.

 

What is the best way to prevent skin cancer?

The best way to avoid skin cancer is to limit your exposure to the sun. Excessive exposure to ultraviolet rays from the sun is the leading cause of skin cancer.  This means developing good habits such as photoprotection with limitation of sun exposure, protective clothing and use of sunscreen.

How do I protect myself from the sun?

1. Generously apply sunscreen to all exposed skin, including lips.

2. Wear protective clothing such as long sleeves, a wide-brimmed hat, and sunglasses if possible.

3. Seek shade. The sun's rays are strongest between the hours of 10 a.m and 4 p.m.

4. Use extra caution near water, snow and sand because they reflect the damaging rays of the sun, increasing risk of sunburn.

5. Protect children from sun exposure.

6. Get vitamin D through vitamin supplements. Don't seek the sun.

7. Avoid tanning beds.

 

Which sunscreen should I use?

The best sunscreen for you depends on your skin type; however, any sunscreen with a sun protection factor (SPF) of 30 or more is a good place to start. 

Use a sunblock with a broad-spectrum protection from both ultraviolet A (UVA) and ultraviolet (UVB) rays. Re-apply every two hours and after expose to water through swimming or sweating.

People who are sensitive to sunscreens should look for chemical-free sunscreens. These products typically contain titanium dioxide and zinc oxide that reflect rather than absorb the sun's rays. They are usually much less likely to cause a skin reaction.

Ask your dermatologist if he or she recommends a special sunscreen for your skin type.

Over-the-counter wrinkle creams and lotions may help dry skin and make it look and feel better, however they do nothing to prevent or reverse wrinkles.

What Sunscreens are Safe for Kids?

The US Food and Drug Administration (FDA) has approved sunscreens as safe for both children and adults. Dermatologists recommend a sunscreen with an SPF of 45 or higher. The most important thing about sunscreens is to remember to apply early, enough and often. "Early" would refer to about 20 to 30 minutes before going outdoors. "Enough" would be making sure that you're using enough sunscreen— usually about an ounce, or two tablespoons, over the entire body. Remember to rub in well! "Often" means every two to three hours while outdoors, but more frequently if in water or sweating. Apply sunscreen every hour if you're swimming or more often if you're going to be toweling off, sweating or potentially rubbing off the sunscreen; in those cases, you should reapply as soon as you do those activities.

 

Who gets acne?

Many people have acne. It is the most common skin problem in the United States. About 40 to 50 million Americans have acne at any one time.

Most people who have acne are teenagers or young adults, but acne can occur at any age. Newborn babies can get acne. Men and women get acne. Some women get acne when they reach middle age.

 

What causes acne?

Acne appears when a pore in our skin clogs. This clog begins with dead skin cells. Normally, dead skin cells rise to surface of the pore, and the body sheds the cells. When the body starts to make lots of sebum (see-bum), oil that keeps our skin from drying out, the dead skin cells can stick together inside the pore. Instead of rising to the surface, the cells become trapped inside the pore.

Sometimes bacteria that live on our skin, p. acnes, also get inside the clogged pore. Inside the pore, the bacteria have a perfect environment for multiplying very quickly. With loads of bacteria inside, the pore becomes inflamed (red and swollen). If the inflammation goes deep into the skin, an acne cyst or nodule appears.
