Let’s face it: moles, skin tags, and warts are irritating. Plus, they can be confusing. Most people just don’t know the difference between them.
The good news: none of them cause a risk to your health. But they’re annoying, and it makes your life more comfortable to get rid of them before they become a problem. So, if you want to know what you’re dealing with before you schedule a spot removal, here’s how to tell the difference between a mole, a wart, and a skin tag.
Warts pop up on your hands, knees, or the bottom of your feet. Unlike moles, they’re hard bumps that lie deep in the skin. Although they may be smooth on top, they’re thick, scaly, and callus-like underneath. Warts start from a virus. And like all viruses, they’re contagious. So, when you see a wart pop up, that means you came into contact with someone else with a wart virus, whether through shaking hands or using the same hand towel.
Although we recommend removing any of these spots, warts especially need to be removed quickly (before you pass the virus along to someone else). But when people try to treat them at home, they never seem to get better. Why? They’re a virus that lives in the skin cells. If you don’t get rid of the virus, you won’t get rid of the wart. So you have to treat it long enough to kill all the skin cells that contain the virus.
Wart treatments are painful. If people start an over-the-counter treatment, they often second-guess themselves when the area starts to hurt. They realize they don’t know what they’re doing, and they can’t stand the pain. So they stop the treatment too soon for it to be effective.
For the fastest wart treatment, ask your dermatologist to freeze the wart. This kills the cells containing the virus so your skin can heal wart-free.
This little flap of skin forms because of friction. It’s been rubbed by a collar, clothing, or sometimes it comes from skin rubbing against skin, particularly under the arm. It starts as a small bump or gland in the skin. Then, once it starts rubbing, there’s a snowball effect. The little ball of skin cells gets pulled up further and further until it’s hanging by a thread. You end up with a ball of skin attached by a thin pedestal.
You’ll know it’s different from a wart or mole because of its pedestal base. Remember, warts are flat on top and go deeper into the skin, but a little ball of skin dangling from the surface is a skin tag.
The biggest problem with skin tags is the irritation they cause. They can snag, bleed, and hurt. In general, they just bother you. But it’s easily fixed by a dermatologist if you want it removed.
Moles are the most serious of these three skin issues. They form slowly, taking a long time to grow. If they become cancerous, they begin to change.
To see a visual difference between wart and mole bumps, look for pigment and hair. Warts don’t have either, but moles have both. Because of their pigment, they have the rare potential to change from a regular mole into skin cancer.
Did you know? Some people are predisposed to develop moles, and sun exposure stimulates them. So, if you notice these small benign growths pop up easily on your skin, take extra precautions in the sun to prevent more from forming.
Moles & Warts vs. Skin Cancer
None of these skin issues are dangerous to begin with, but they can become dangerous if certain changes start to happen. Here are the early warning signs that your mole, bump, or wart is developing into something more serious.
Normal moles are either brown or tan — not multi-colored. If your mole seems to be various colors — brown, tan, black, and even red — that’s an early warning sign it’s developing into something else.
Moles are also generally round in shape. If your spot is asymmetrical and continues to increase in size, it may be skin cancer.
Moles can be either flat or raised — but they don’t typically change unless they’re dangerous. If a spot changes from flat to raised, that’s a warning sign.
Any time a mole seems to change or become irregularly colored, visit your dermatologist. Sometimes it’s hard to tell whether or not a spot is dangerous. It’s always best to let a professional make that determination. If you’re dealing with an atypical mole, they’ll likely remove it and send it off for testing.

Elevated Bump or Wart-Like Growth
Bumps, blisters, and warts are common. Usually, there’s nothing to fear. However, heed the warning if a spot doesn’t disappear within six weeks. Certain skin cancers can look like a wart or blister, and most are easily treated if you catch them early.
Wart/Sore That Bleeds or Won’t Heal
Pay attention to any wart or sore that doesn’t seem to heal. If it starts to bleed, that’s another sign it could be problematic. If you have a new growth or sore that isn’t healing, visit your dermatologist to have it professionally examined.
Know the ABCs of Melanoma
If you have an atypical mole or another spot that looks suspicious, remember “ABCDE” to check for early features that indicate melanoma.
- Asymmetry: If you drew a line down the middle, the sides would not match.
- Border: The edges of the spot are ragged, notched, or blurred. The pigment appears to fade into the skin.
- Color: The color is not uniform. The spot contains shades of black, brown, and tan (and maybe white, gray, red, pink, or blue).
- Diameter: Melanoma can range in size, but most are larger than six millimeters in diameter.
- Evolving: Look for changes in the spot over several weeks or months.
Should You Try DIY Treatments?
It can be tempting to try to remove these growths yourself. It’s probably bothering you, but maybe you don’t have time to see a professional. Your skin tag, mole, or wart isn’t dangerous — yet you can cause an infection if you try to remove it on your own.
More often than not, people aren’t successful with DIY spot removal treatments. So save yourself the frustration, and let a dermatologist take care of it.
Whether you have a mole, wart, or skin tag, a board-certified dermatologist can give you the most accurate identification and help you decide if the growth should be removed.
