Melanoma is the deadliest form of skin cancer, accounting for 75% of all skin cancer deaths. This type of cancer develops when pigment-producing cells called melanocytes mutate and start to grow uncontrollably.
It can be caused by a combination of genetic and environmental factors, such as prolonged sun exposure and a weakened immune system. While many people are aware of some of the more common signs of melanoma, such as changes in moles, there are some less recognized symptoms that could be indicative of this dangerous disease.
Below are 5 unrecognized signs of melanoma that you should know:.
1. A Spot That Looks Like a Bruise
Some melanomas may look like a bruise or a dark red spot on the skin. If you notice a spot on your skin that does not go away after a few weeks, and especially if it is painful or bleeding, you should have it checked by a dermatologist.
These spots may not look like the usual melanoma moles, but they can still be very dangerous.
2. A Dark Streak Under a Nail
When melanoma develops under the nail, it can appear as a dark streak that runs from the base of the nail to the tip. This type of melanoma is called subungual melanoma and is more common in people with darker skin.
Since it is often mistaken for a bruise or a melanoma-free stripe, it may not be detected until it has progressed to a more advanced stage.
3. A Pink or Red Bump
Not all melanomas are brown or black. Some may present as a pink or red bump on the skin. Known as amelanotic melanoma, they may be harder to detect and diagnose. These types of melanoma are often mistaken for a harmless spot or a dermatitis rash.

They can also bleed easily and scab over, making it easy to dismiss them as a minor skin problem.
4. A Painful Itch
While most moles and other skin spots do not cause any discomfort, melanoma lesions can be painful or itchy. A lesion that bleeds, crusts over, or causes a burning sensation should be checked by a dermatologist.
Itchiness is often a sign that the melanoma is invading surrounding tissues or has metastasized to other parts of the body.
5. A Lesion on the Sole of the Foot
Melanoma can occur anywhere on the body, including the soles of the feet. These types of melanoma are often overlooked or mistaken for a plantar wart or a callus.
Since melanomas on the soles of the feet can be flat and spread out, they are harder to detect. They may also be painful or cause difficulty walking.
Conclusion
While it is important to keep an eye on any moles or spots that appear on the skin, it is also important to be aware of the less recognized symptoms of melanoma.
If you notice any of the above-mentioned signs, do not hesitate to consult a dermatologist who can conduct a thorough examination and provide a proper diagnosis.
