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.
Are cancerous moles flat or raised?
Spreading color — Melanomas can be a variety of colors, and the color may spread from the edge into the surrounding tissue. Elevation — A flat or slightly raised mole grows higher very quickly. Surrounding skin — The skin around a mole becomes red or develops colored blemishes or swelling.
Can melanoma be small and flat?
D is for Diameter: The spot is larger than 6 millimeters across (about ¼ inch – the size of a pencil eraser), although melanomas can sometimes be smaller than this. E is for Evolving: The mole is changing in size, shape, or color.
Why is my mole flat?
A disappearing mole may begin as a flat spot, gradually become raised, then get light, pale, and eventually disappear. This natural evolution of moles rarely indicates cancer. However, when a mole does disappear suddenly, it may be due to melanoma or another type of skin cancer.
Are suspicious moles always cancerous?
Removing a suspicious mole and examining it for cancer cells is an important step in catching melanoma early, when it’s easiest to treat. During a skin cancer screening exam your dermatologist may find an abnormal mole. An abnormal mole could be a melanoma symptom, or it could be benign, meaning it’s not cancerous.
What does an early stage melanoma look like?
Melanoma borders tend to be uneven and may have scalloped or notched edges, while common moles tend to have smoother, more even borders. C is for Color. Multiple colors are a warning sign. While benign moles are usually a single shade of brown, a melanoma may have different shades of brown, tan or black.
What is early stage melanoma?
Stage I: The cancer is smaller than 1 mm in Breslow depth, and may or may not be ulcerated. It is localized but invasive, meaning that it has penetrated beneath the top layer into the next layer of skin.
What are the 4 types of melanoma?
There are 4 main types of melanoma skin cancer – superficial spreading, nodular, lentigo maligna and acral lentiginous.
How quickly does melanoma grow?
Melanoma can grow very quickly. It can become life-threatening in as little as six weeks and, if untreated, it can spread to other parts of the body. Melanoma can appear on skin not normally exposed to the sun. Nodular melanoma is a highly dangerous form of melanoma that looks different from common melanomas.
Can you get rid of flat moles?
Some moles can be removed using lasers. This is most commonly done with small, flat, non-cancerous moles. During laser removal, your doctor will use bursts of light radiation to destroy the mole tissue. To fully remove a mole using laser therapy, you may need to have two or three treatments.
Can a flat mole become raised?
At first, moles are flat and tan like a freckle, or they can be pink, brown, or black in color. Over time, they usually enlarge and some develop hairs. As the years pass, moles can change slowly, becoming more raised and lighter in color. Some will not change at all.
What does a suspicious mole look like?

Can you have a cancerous mole for years?
They can change or even disappear over the years, and very rarely can become skin cancers. Some research suggests that having more than 50 common moles may increase one’s risk of melanoma.
Can a dermatologist tell if a mole is cancerous?
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.
Does a cancerous mole itch all the time?
This irritating can make them itch. Most moles are normal, and they’re usually harmless. But sometimes they can turn cancerous. An itchy mole, along with other changes like crusting and bleeding, could be a sign of melanoma.
