Understanding the ABCs of Skin Cancer: Signs and Prevention

Skin cancer is one of the most common types of cancer, but with the right knowledge and precautions, it is also one of the most preventable. At SINY Dermatology, we are dedicated to helping you understand the signs of skin cancer and how to protect yourself effectively.

The ABCs of Skin Cancer

The ABCDEs of melanoma are a simple guide to identifying potential skin cancer. Each letter stands for a key characteristic to watch out for:

A for Asymmetry: One half of the mole or spot is unlike the other half.
B for Border: Look for moles with irregular, scalloped, or poorly defined borders.
C for Color: Beware of moles with multiple colors such as shades of brown, black, white, red, or blue.
D for Diameter: Moles larger than 6mm (about the size of a pencil eraser) should be checked, although melanomas can be smaller.
E for Evolving: Any change in size, shape, color, or elevation of a spot on your skin, or any new symptom such as bleeding, itching, or crusting, indicates a need for further evaluation.

Prevention Tips

Use Sunscreen: Apply a broad-spectrum sunscreen with an SPF of at least 30 every day, even on cloudy days. Reapply every two hours, and after swimming or sweating.
Seek Shade: Avoid direct sun exposure, especially between 10 a.m. and 4 p.m. when the sun’s rays are strongest.
Wear Protective Clothing: Long sleeves, wide-brimmed hats, and sunglasses can shield your skin from harmful UV rays.
Avoid Tanning Beds: The UV light from tanning beds increases the risk of skin cancer.
Perform Regular Skin Checks: Examine your skin from head to toe every month. Use a mirror to check hard-to-see areas and ask for help to inspect your back.

When to See a Dermatologist

Early detection is key to successful treatment of skin cancer. Schedule an annual skin exam with a dermatologist who can expertly identify any suspicious changes. If you notice any of the ABCDE signs or other unusual changes in your skin, don’t wait—consult with a dermatologist immediately.
