Read on to find out more—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had COVID.


If A Mole Changes In These Ways, See a Doctor

Experts advise checking your skin regularly and applying the ABCDE test to any moles or freckles. If you notice any of the following, it's a good idea to consult a doctor ASAP:

A = asymmetry

B = border changes

C = color changes

D = diameter changes (such as an increase in size)

E = elevation or evolution (a growth that has changed over time)

The American Academy of Dermatology says that in addition to changes, if you see any spot on your skin that's different from the others, or see any itching or bleeding, you should make an appointment with a board-certified dermatologist.


When Is Size a Concern?

The AAD says that although most melanomas are greater than the size of a pencil eraser—about six millimeters—melanoma is often diagnosed when it's smaller. About 50 percent of melanomas are self-detected. 


When Is Color a Concern?

According to the AAD, a spot that's suspicious for cancer may have varying colors from one area to the next, such as shades of tan, brown or black, or areas of white, red, or blue. Irregular, scalloped or poorly defined borders can also be a sign of skin cancer.


How to Do a Skin Self Exam

These are the steps the AAD advises you take in doing a skin self-exam:

  • Check your body in a full-length mirror, both sides with your arms raised
  • Examine your underarms, forearms, and palms
  • Look at your legs, the soles of your feet, and between your toes
  • Use a hand mirror to check your hair and scalp
  • Use a hand mirror to check your back and buttocks

How to Reduce Your Risk of Skin Cancer

To reduce your risk of skin cancer, the CDC advises limiting your exposure to ultraviolet (UV) radiation, which is produced by the sun and tanning beds. Those steps include avoiding indoor tanning and protecting your skin from the sun, particularly when the UV Index in your area is above 3. The protective steps include staying in the shade, wearing clothes that protect your arms and legs, wearing a hat, and wearing an broad spectrum sunscreen with an SPF of 15 or higher.
