How can you tell the difference between a benign and malignant mole?
Melanoma lesions are often irregular, or not symmetrical, in shape. A non-cancerous mole is typically symmetrical in shape. If you were to draw a line through the middle of a mole, the two halves should roughly match. Typically a non-cancerous mole will have smooth, even borders.
What does a mole look like if it is cancerous?
A cancerous mole will have edges that look ragged, notched or blurred. Uneven color: A normal mole will have a single shade of brown that is evenly distributed throughout. A cancerous mole will have shades or hues of black and brown. In between, areas of red, pink, white, gray or blue may also be seen.
What does a non cancerous mole 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.
Can a doctor tell if a mole is cancerous just by looking at it?
Unfortunately, you can’t tell by looking at a mole whether it’s cancerous or what type it is. It could very well be a normal skin spot with an abnormal appearance. A dermatologist can’t always tell the difference either.
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.
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.
When should a mole be checked?
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.
How long does it take for a mole to turn cancerous?
Melanoma can grow very quickly. It can become life-threatening in as little as 6 weeks and, if untreated, it can spread to other parts of the body. Melanoma can appear on skin not normally exposed to the sun.
What does a harmless mole look like?
If you remember, one of the typical features of benign moles is that they have a consistent color throughout. This mole, however, is flesh colored on the perimeter and brown in the center.
Can a growing mole be benign?
Moles are benign (noncancerous) growths of the skin caused by the proliferation of melanocytes, which produce the dark protective pigment in the skin called melanin. Most moles appear in individuals during their 20s, though some may appear later in life and some may be present at birth.
Can benign moles be raised?
Types of benign moles
The most common types of benign mole include: Compound melanocytic nevi, which are usually raised above the skin, light brown and sometimes hairy. Dermal melanocytic nevi, which are usually raised, pale and sometimes hairy.
What does Stage 1 melanoma mean?
In Stage I melanoma, the cancer cells are in both the first and second layers of the skin—the epidermis and the dermis. A melanoma tumor is considered Stage I if it is up to 2 mm thick, and it may or may not have ulceration. There is no evidence the cancer has spread to lymph nodes or distant sites (metastasis).
What percentage of suspicious moles are cancerous?
A study published in the Journal of the American Academy of Dermatology suggests around 7% of suspicious mole removal is cancerous. This number drops when accounting for all moles removed, as most are benign (non-cancerous).
Is it a skin tag or mole?
Most moles are harmless and don’t cause pain or other symptoms unless you rub them or they bump against something. Skin tags are small, soft pieces of skin that stick out on a thin stem. They most often appear on the neck, armpits, upper trunk, and body folds. The cause of skin tags is not known.
