Changes in your skin can be concerning, especially when moles, skin tags, or dark spots appear. While many of these growths are harmless, some warrant seeing a dermatologist. Here’s how to tell the difference between these common skin conditions and warning signs that they might be cancerous.

When to Pay Attention to Moles

Moles are small, brown or black spots on the skin resulting from clusters of pigmented cells. They can be flat or raised, and some may even sprout dark, coarse hair. The vast majority of moles are harmless, but certain characteristics indicate a problem. Watch for changes using the ABCDE rule:

Asymmetry: One half of the mole looks different than the other.
Borders: The edges become uneven or blurred.
Color: The color varies across the mole.
Diameter: It’s larger than 6mm (about the size of a pencil eraser).
Evolving: The mole changes in size, shape, or texture, or it begins to itch or bleed.

If you notice any of these signs, consult a dermatologist, as they could be early indicators of melanoma, a type of skin cancer.

Usually Harmless but Sometimes Annoying Skin Tags

Skin tags are small, brown or flesh-colored bumps that often develop in areas where skin rubs against skin, like the neck, armpits, and groin. They are typically soft and malleable, making them easy to move. This trait distinguishes skin tags from warts, which are usually rough and firm to the touch.

While skin tags are generally harmless, they can cause irritation if caught on clothing or jewelry. Attempting to shave over a skin tag may also cause injury. If a skin tag becomes painful, grows rapidly, or changes in appearance, it’s worth having a dermatologist check it out.

When to Be Concerned About Dark Spots

Dark spots, or hyperpigmentation, are usually harmless and often result from sun exposure or aging. These spots can range from light brown to almost black, and they typically appear on areas of the skin that see the most sun, such as the face and hands.

Melasma is a specific form of hyperpigmentation typically appearing as large, symmetrical patches on the face. This condition is usually triggered by hormonal changes, such as pregnancy or birth control use. However, if a dark spot has an irregular shape or changes over time, it’s best to have it examined to rule out melanoma.

Schedule Your Appointment

While moles, skin tags, and dark spots are often benign, it’s wise to monitor your skin for changes. Rapid growth, pain, itching, or discharge should prompt a visit to the dermatologist. Early detection leads to more effective skin cancer treatment.
