The ABCDE Rule of Skin Cancer: Empowering Rural Minnesotans to Prevent Cancer

Know the Signs, Save Your Life

While skin cancer and melanoma rates have been steadily rising for the past three decades, every Minnesotan has the power to prevent these deadly diseases. The ABCDE rule for skin cancer is a simple and effective tool that can help you identify potential skin cancers early on, when treatment is most effective.

The letters in the ABCDE rule stand for:

Asymmetry

Is the spot symmetrical, or is one half different from the other?

Border

Is the border of the spot irregular, ragged, or blurred?

Color

Is the spot a uniform color, or are there different shades of brown or black?

Diameter

Is the spot larger than 6 millimeters (about the size of a pencil eraser)?

Evolving

Has the spot changed in size, shape, or color over time?

If you notice any of these signs, it's important to see a dermatologist right away. Early detection is key to successful treatment of skin cancer.

By following the ABCDE rule and performing regular skin self-exams, you can take an active role in preventing skin cancer and protecting your health.
