Skin cancer is the most common type of cancer in the United States, affecting millions of people each year. Early detection is key to successful treatment, so it’s important to know how to identify the signs and seek prompt medical attention if you suspect you may have it.

Here are the ABCs of skin cancer identification:

A: Asymmetry

One of the most common signs of skin cancer is asymmetry, meaning that one half of a mole or spot doesn’t match the other half. If a mole or spot is asymmetrical, it’s important to have it checked by a doctor.

B: Border

A suspicious mole or spot may have irregular or poorly defined borders, meaning that the edges are not smooth and clear. This can be a sign and should be evaluated by a doctor.

C: Color

If a mole or spot is not a uniform color, but instead has several shades of brown, black, or other colors, it’s important to have it checked by a doctor.

D: Diameter

The size of a mole or spot can also be a sign. If a mole or spot is larger than the size of a pencil eraser, it’s important to have it checked by a doctor.

E: Evolving

Skin cancer often involves changes to the appearance of a mole or spot, so it’s important to pay close attention to any changes you may notice.
