Normal moles are symmetrical, small, and flat. They have a smooth border and consistent coloration. Melanomas are often asymmetrical, larger than 6mm, and elevated. They have irregular borders and inconsistent coloring.
Are all moles with irregular borders cancerous?
Benign moles typically have a regular, round border. Cancerous moles tend to have irregular borders. If the border isn’t smooth, you should get your mole checked out. Benign moles are usually one uniform color throughout.
Can a normal mole have uneven edges?
Dysplastic nevi tend to have uneven color with dark brown centers and lighter, uneven edges. These moles tend to be hereditary (inherited), and people who have them may have more than 100 moles. If you have dysplastic nevi then you have a greater chance of developing malignant (cancerous) melanoma.
Can moles be irregular shape?
Atypical moles can also be flat or raised. They also have these characteristics: They measure more than 1/4 inch (5 mm) across — larger than the size of a pencil eraser. They are irregularly shaped, with uneven borders that may fade into the skin around the mole.
Can normal moles be different shades?
There are many different types of moles. Moles can vary significantly in appearance. For example: the colour can be pink, red, blue or varied shades from light to dark brown.
What does Stage 1 melanoma look like?
Stage I melanoma is no more than 1.0 millimeter thick (about the size of a sharpened pencil point), with or without an ulceration (broken skin). There is no evidence that Stage I melanoma has spread to the lymph tissues, lymph nodes, or body organs.
Are changing moles always cancerous?
No, changing moles do not always equate to skin cancer and most moles are usually harmless. It can be normal for moles to change in number and appearance; some can also disappear over time. For example, hormonal changes during puberty and pregnancy can cause moles to increase in number and become darker.
Is melanoma raised or flat?
The most common type of melanoma usually appears as a flat or barely raised lesion with irregular edges and different colours. Fifty per cent of these melanomas occur in preexisting moles.
Can melanoma be symmetrical?
Most melanomas are asymmetrical. If you draw a line through the middle of the lesion, the two halves don’t match, so it looks different from a round to oval and symmetrical common mole.
What do non cancerous moles look like?
While benign moles are usually a single shade of brown, a melanoma may have different shades of brown, tan or black. As it grows, the colors red, white or blue may also appear. D is for Diameter and Dark.
How do I know if my mole is bad?
It’s important to get a new or existing mole checked out if it:
- changes shape or looks uneven.
- changes colour, gets darker or has more than 2 colours.
- starts itching, crusting, flaking or bleeding.
- gets larger or more raised from the skin.
Can atypical moles look like melanoma?
Atypical moles are very similar to melanoma: both are asymmetrical, multicolored, have an irregular border, and can grow over time. While not all atypical moles are precancerous moles, they can become cancerous moles or melanoma.
Can moles be different shapes?
Atypical moles are usually bigger than 6 mm wide (about the size of a pencil eraser). They have an asymmetric shape and an uneven or jagged border. Atypical moles are usually more than two different shades of brown and are not the same color throughout (see drawing).
Can moles have a dark center?
Moles known as dysplastic nevi or atypical moles are larger than average (usually larger than a pencil eraser) and irregular in shape. They tend to have uneven color with dark brown centers and a lighter, sometimes reddish, uneven border or black dots at the edge.
Can a normal mole have 2 colors?
A mole that has more than one colour needs to be evaluated by a doctor. There are some exceptions to the rule, as the mole can be two shades of brown (light brown and dark brown), but that should also be evaluated by a trained professional.
