Moles are common skin features that many people have. Most are harmless, and some are even considered beauty marks. However, not all moles are benign. In some cases, a mole can be an early sign of melanoma, a dangerous form of skin cancer. What’s more concerning is that certain locations on the body where moles appear may carry a higher risk of turning cancerous — and these areas are often overlooked.

Medical experts are warning people not to ignore moles, especially when they appear in these three high-risk locations. Early detection and awareness can make a life-saving difference.

1. The Scalp

The scalp is one of the most easily forgotten areas when it comes to skin care and mole monitoring. Because it’s often hidden under hair, people rarely inspect their scalp for changes. However, this area receives direct sun exposure, especially in individuals with thinning hair or who spend a lot of time outdoors without head protection.

Melanoma on the scalp is particularly dangerous because it is often detected late. It tends to grow more aggressively in this location and can spread quickly to other parts of the body. Dermatologists recommend that people — especially men who are balding — ask their barber or hairstylist to alert them to any unusual spots or growths. Regular checks using a mirror or asking a family member for help can also be beneficial.

2. The Soles of the Feet

It might seem surprising, but the soles of the feet are another area where dangerous moles can develop. This condition, called acral lentiginous melanoma, is more common in people with darker skin tones but can occur in anyone. Because the feet are not typically associated with sun exposure, people may delay checking them or dismiss early warning signs as blisters or calluses.

Moles on the feet, especially ones that change shape, grow rapidly, or start to bleed, should be examined immediately. Ignoring them can allow the cancer to spread unchecked. Always include your feet in routine skin checks, and never hesitate to consult a dermatologist about any unusual spots.

3. Under the Nails (Nail Beds)

Another easily overlooked location is under the fingernails or toenails. A dark streak or mole in the nail bed might be mistaken for a bruise or a fungal infection. However, this could be a sign of subungual melanoma, a rare but aggressive form of skin cancer.

It often appears as a brown or black streak that doesn’t grow out with the nail and may be accompanied by discoloration of the surrounding skin or nail splitting. This type of melanoma is often diagnosed at a later stage because it looks so similar to other benign nail conditions. If you notice a persistent mark under your nail that doesn't improve over time, seek medical advice promptly.

Don't Ignore the Warning Signs

While most moles are harmless, changes in their appearance or the emergence of new moles in unusual places should never be ignored. Doctors advise following the ABCDE rule to evaluate moles:

• Asymmetry

• Border irregularity

• Color variation

• Diameter larger than 6mm

• Evolving in size, shape, or color

If a mole meets any of these criteria — especially in the scalp, on the feet, or under the nails — it's crucial to seek medical attention. Early diagnosis is key to treating skin cancer successfully.

Conclusion

Skin cancer is one of the most common yet preventable forms of cancer. The danger lies in neglect and underestimation. These three mole locations — scalp, soles, and under the nails — are often forgotten in routine checks but can be hotspots for serious conditions. By staying vigilant and understanding the risks, you can protect yourself and your loved ones. Remember: it's not just about how a mole looks, but where it appears. Don’t wait — check your skin regularly, and when in doubt, consult a professional.
