Melanoma signs and symptoms colour - a mole may change in colour, have different colour shades or become blotchy. size - a mole may appear to get bigger. shape - a mole may have an irregular shape, may increase in height or not be symmetrical. elevation - the mole may develop a raised area.
If you notice changes in any mole's color, thickness, size, or shape, you should see a dermatologist. You also should have your moles checked if they bleed, ooze, itch, scale, or become tender or painful.
Look for moles with irregular shapes, such as two very different-looking halves. B is for irregular border. Look for moles with irregular, notched or scalloped borders — characteristics of melanomas. C is for changes in color.
Only rarely does a dysplastic nevus turn into melanoma (1, 3). However, dysplastic nevi are a risk factor for developing melanoma, and the more dysplastic nevi a person has, the greater their risk of developing melanoma (1, 3).
Stage 1: the central part is brown. Stage 2: the central part of the lesion becomes depigmented to form a pinkish raised lesion or papule. Stage 3: the papule regresses and the central area remains colorless. Stage 4: repigmentation progresses to transform the earlier location of the nevus into ordinary skin.
The procedure that your dermatologist uses to remove the spot is called a skin biopsy. Having a skin biopsy is essential. It's the only way to know whether you have skin cancer. There's no other way to know for sure.
Talk to your doctor if you notice changes in your skin such as a new growth, a sore that doesn't heal, a change in an old growth, or any of the A-B-C-D-Es of melanoma. A change in your skin is the most common sign of skin cancer. This could be a new growth, a sore that doesn't heal, or a change in a mole.
Pigment, redness or swelling that spreads outside the border of a spot to the surrounding skin. Itchiness, tenderness or pain. Changes in texture, or scales, oozing or bleeding from an existing mole. Blurry vision or partial loss of sight, or dark spots in the iris.

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.
Features of the nevus can be very helpful to predict the risk of growth. These features include: the size and thickness, the presence of orange pigment, fluid leakage over the surface of the nevus, presence of drusen, and location within the eye. Larger and thicker nevi are commonly referred to as a suspicious nevus.
Small- and medium-sized nevi are generally harmless but can be removed for aesthetic reasons. Removal of a small nevus consists of a simple excision, cutting out the affected area and stitching the surrounding skin back together.
A very small percentage of melanocytic nevi may develop a melanoma within them. Of note, the majority of cutaneous melanomas arise within normally appearing skin. Benign nevi are usually a single color, ranging from skin-colored to dark brown. They are typically round or oval-shaped.
Blood tests. Blood tests aren't used to diagnose melanoma, but some tests may be done before or during treatment, especially for more advanced melanomas. Doctors often test blood for levels of a substance called lactate dehydrogenase (LDH) before treatment.
How melanoma is diagnosed. For melanoma, a biopsy of the suspicious skin area, called a lesion, is the only sure way for the doctor to know if it is cancer. In a biopsy, the doctor takes a small sample of tissue for testing in a laboratory.
Color that is uneven: Shades of black, brown, and tan may be present. Areas of white, gray, red, pink, or blue may also be seen. Diameter: There is a change in size, usually an increase. Melanomas can be tiny, but most are larger than the size of a pea (larger than 6 millimeters or about 1/4 inch).
A visual check of your skin only finds moles that may be cancer. It can't tell you for sure that you have it. The only way to diagnose the condition is with a test called a biopsy. If your doctor thinks a mole is a problem, they will give you a shot of numbing medicine, then scrape off as much of the mole as possible.
Color: Whereas a common mole is one color, a precancerous mole is often a mixture of various colors like brown, black, red, or blue. Diameter: The larger the mole, the more likely it is precancerous. If a mole is larger than five millimeters, it should be evaluated by a doctor.
Generally, after a patient receives positive melanoma results, his or her doctors will need to proceed with staging the malignancy— which essentially means determining the extent of the cancer—and developing a treatment plan based on how far the cancer has progressed.
Although growth is a normal part of the nevus life cycle, limited data are available to help physicians distinguish normal from abnormal growth.
Dysplastic nevus is a mole that looks different from most moles. The mole may have irregular borders, be a mix of colors and appear larger than other moles. Atypical moles are benign (not cancerous). However, having a lot of atypical moles increases your risk of melanoma, a life-threatening skin cancer.
Your ophthalmologist can find a nevus during a routine eye exam. In some cases, your ophthalmologist may use imaging technology like OCT to examine a nevus more closely, such as a choroidal nevus. The ophthalmologist will take a picture of the nevus.
