Melanoma (Skin Cancer) Symptoms

Melanoma is a type of skin cancer, which develops in the cells called melanocytes. These cells are responsible for producing melanin, the pigment that gives color to the skin. In women, melanoma is most often seen in the lower legs, while the most common site in men is the back.

Melanoma is responsible for the majority of deaths related to skin cancers. The exact cause of melanoma is not clear, but it is usually associated with DNA damage resulting from exposure to ultraviolet (UV) light from the sun.

Risk Factors

Some of the factors that may increase your risk of developing melanoma include:

People with no risk factors or darker skin can also develop melanoma. People with darker skin are more vulnerable to hidden melanomas in areas like the soles of feet and palms of hand that do not receive sun exposure.

Warning Signs and Symptoms

Early detection helps in the treatment of melanoma. Treatment options include surgery, chemotherapy, radiation, biologic and targeted therapies. If not detected early, melanoma can spread to other parts of the body and can be deadly.

Here are some of the warning signs and symptoms that you should not ignore.

New mole

One possible sign is a new mole appearing unexpectedly after the age of 21 that is asymmetrical, has an irregular outline and is bigger than 6 mm or ¼ inch in diameter. There can be one or more new moles.

An unusual skin spot

Another important warning sign of melanoma is a spot that looks different from all of the other spots on your skin (known as the ugly duckling sign).

Changes in a mole’s appearance

Changes in color, diameter, shape or size of an existing mole, birthmark, or a pigmented area can also be a sign of melanoma.

It can increase in size and appear pearly, translucent, tan, brown, black or multicolored. Also, there can be symptoms like a scaly appearance, bleeding or oozing, or the appearance of a bump or nodule.

Change in sensation

A particular spot or sore on the skin that continues to itch, hurt, crust, scab, erode or bleed should not be ignored. Changes in sensation in the forms of itchiness, tenderness or pain can also be warning signs of melanoma.

An open sore

An open sore that does not heal within three weeks can be an early sign of skin cancer.

New pigmented area

A new pigmented area or splotch that appears darker than your normal skin tone can be a cancer sign. The darker skin area may be very small.

If you notice any of these signs and symptoms on your skin, do not overlook them. Make an appointment with a dermatologist to have them checked. At the same time, take precautions to prevent skin cancer.
