The ABCs of skin cancer: signs, symptoms, and prevention

Skin cancer is the most common type of cancer in the United States, and its incidence continues to rise each year. While skin cancer is highly treatable when detected early, it can be deadly if left unchecked. Fortunately, there are steps you can take to prevent skin cancer and catch it in its early stages.

One useful tool for detecting skin cancer is the ABCDEs of skin cancer. These are the signs and symptoms you should be on the lookout for when examining your skin. Let’s break down each of the ABCDEs:

A: Asymmetry. One half of a mole or birthmark does not match the other half.

B: Border. The edges of a mole are irregular, ragged, blurred, or notched.

C: Color. The color of a mole is not the same throughout or has shades of tan, brown, black, blue, white, or red.

D: Diameter. The size of a mole is larger than a pencil eraser.

E: Evolving. A mole is changing in size, shape, or color.

If you notice any of these signs or symptoms, it’s important to see a dermatologist right away. Your dermatologist can perform a skin exam and, if necessary, biopsy the affected area to determine if it is cancerous.

In addition to being vigilant about the signs and symptoms of skin cancer, there are steps you can take to prevent it. One of the most important things you can do is protect your skin from the sun’s harmful rays. This means wearing protective clothing, such as hats and long sleeves, and using sunscreen with an SPF of at least 30. It’s also important to avoid tanning beds, which can increase your risk of skin cancer.

Another key factor in preventing skin cancer is regular skin exams. You should perform a self-exam of your skin once a month and see a dermatologist for a professional skin exam
