What Are the Symptoms of Melanoma?

Moles on the skin are common and harmless. They are either brown or black in color and round or oval in shape. However, if some moles are different sizes, shapes, and colors compared to the others, it is imperative that you seek medical examination to rule out the possibility of melanoma.

• The edge of mole is blurred and irregular in shape and rough and dented in texture.

• The mole changes in size, shape, and color.

• The mole contains multiple colors, including brown, black, pink, and white.

• The color of mole bleeds onto neighboring skin.

• The mole is red and swollen and affects the peripheral region of the skin, turning it red and swollen as well.

• The mole is ulcerative and slow to heal.

Melanoma is a type of skin cancer that develops from the transformation of pigment-containing cells, called melanocytes, to cancerous cells in the skin. The skin consists of three layers—namely, the epidermis, dermis, and subcutaneous layers. The epidermis layer consists of several types of cells, including melanocytes. Melanocytes produce melanin, a dark pigment that makes the color of the skin darken upon sun exposure. Melanoma is caused by the abnormal growth and proliferation of melanocytes. Certain kinds of melanoma continue to produce melanin, causing the tumors to appear black, but others cannot produce melanin, so the tumors appear pink or white. Melanoma affects various areas of the body, such as the face and neck. Melanoma is often found on the chest and back in men and on the legs in women. In the US, it is estimated that 760,000 people will be afflicted with melanoma this year.
