Hi.
I can understand your concerns regarding the appearance of purplish mole like spot on the chest.
The first sign of
melanoma is typically a new spot on the skin, or a change in the size, shape or color of an existing mole.
The 'ABCDE' method may help you determine whether an abnormal skin growth may be melanoma:
Asymmetry: The mole has an irregular shape.
Border: The edge is not smooth, but irregular or notched.
Color: The mole has uneven shading or dark spots.
Diameter: The spot is larger than the size of a pencil eraser.
Evolving or Elevation: The spot is changing in size, shape or texture.
Melanomas may also develop in areas that are usually hidden from the sun. In addition to examining the legs, trunk, arms, face and neck, it is important to look at the areas between the toes, underneath fingernails and toenails, on the palms of the hands, the soles of the feet, the genitals and even the eyes.
I recommend you to be examined by a
dermatologist to make sure that the mole in question is not a melanoma.
Hope I have answered your query.
