Moles are a common feature on most people’s skin. These small, often dark spots are usually harmless, but it’s important to understand the difference between a typical mole and one that could be cancerous. At Rodgers Dermatology, we believe in empowering our patients with the knowledge to protect their skin, and we’ve created this guide to help you learn the difference between moles and skin cancer.
Moles vs. Cancer: Understanding the Difference and When to Seek Help
What are Moles?
A mole, or nevus, is a skin growth that develops when melanocytes (pigment-producing cells) cluster together and a majority of people will develop them during childhood and adolescence. They typically appear as small, dark marks or sometimes as flesh-colored bumps but can vary in color, shape, and size. For example, blue nevi are a type of mole that appears blue because the melanocytes are located deeper in the skin.
While most moles are benign, it’s crucial to monitor them for changes.
Cancerous Moles: What to Watch For
Some can develop into melanoma, a serious form of skin cancer. Overexposure to the sun, particularly during childhood, can increase the number of moles and, consequently, the risk of developing melanoma. Irregular moles, known as dysplastic or atypical nevi, indicate an increased risk, which grows with the number of moles a person has.
Regular skin self-exams are essential for early detection. Familiarize yourself with your skin and monitor your moles for any changes.
When Should You Get a Mole Checked?
Most moles are benign, but any changes in color or appearance should be evaluated by a dermatologist. You should also seek a professional evaluation if a mole:
- Bleeds
- Oozes
- Itches
- Appears scaly
- Becomes tender or painful
Early cancer detection is critical for successful treatment. Regular self-exams play a vital role in identifying potential issues early on.
The 5 Signs to Watch Out For: The ABCDEs of Melanoma
If you notice new or unusual moles, a dermatologist’s expert evaluation is recommended. Here are five key signs to look for:
- Asymmetry: If one half of the mole doesn’t match the other, it’s asymmetrical.
- Borders: Jagged, blurred, bumpy, or irregular edges are a cause for concern.
- Color: Changes in color, especially the appearance of tan, brown, black, blue, white, or red, warrant a professional examination.
- Diameter: Moles larger than the eraser head of a pencil should be checked, especially if you’ve noticed a recent increase in size.
- Evolution: Any changes in a mole’s size, color, or shape should be evaluated promptly.
FAQs About Moles and Skin Cancer
What should I do if I find a red mole on my skin?
Any change in a mole’s color, including the appearance of a red mole, should prompt a visit to your dermatologist. These are different from cherry angiomas (which we can also treat), but any unusually colored mole is a cause for concern. Our skin experts will be able to assess the risk and create an effective treatment plan.
What is the difference between a mole and a freckle?
Moles tend to be raised, whereas freckles are flat. Both are related to melanin, but moles are clusters of skin cells, while freckles are areas with a normal number of pigment-producing cells. Freckles cannot turn into moles.
Can existing moles ever develop into cancer?
Yes, existing moles can develop into melanoma. It’s estimated that 20-30% of melanomas arise from existing moles, while 70-80% develop on seemingly normal skin.
Crucial Tips for Differentiating Moles & Cancer: Early Detection is Key
Identifying potential skin cancer isn’t always easy, as melanomas can appear in various forms and may not display typical warning signs. Learning the ABCDEs of melanoma and the “Ugly Duckling” sign (when a mole looks different from other moles on your body) will make your monthly self-skin exams effective, so you know when to seek a dermatologist’s insight.
“When in doubt, check it out” is our main advice! In addition to seeing a dermatologist annually for a professional skin exam, trust your instincts and see a dermatologist if a spot doesn’t seem right during your regular self-exams.
