Melanomas usually begin as a flat spot that changes in size or shape or colour over months. While they remain flat they are generally curable. They usually remain flat for six to 12 months. Later, melanomas become bigger, irregular in shape and often darker in colour.
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.
What does lentigo maligna melanoma look like? Both forms of lentigo maligna look like a flat or slightly raised brown patch, similar to a freckle or sun spot. They have a smooth surface and an irregular shape. While they are usually a shade of brown, they can also be pink, red or white.
Spread of pigment from the border of a spot into surrounding skin. Redness or a new swelling beyond the border of the mole. Change in sensation, such as itchiness, tenderness, or pain. Change in the surface of a mole – scaliness, oozing, bleeding, or the appearance of a lump or bump.
Redness or new swelling beyond the border of a mole. Color that spreads from the border of a spot into surrounding skin. Itching, pain, or tenderness in an area that doesn't go away or goes away then comes back. Changes in the surface of a mole: oozing, scaliness, bleeding, or the appearance of a lump or bump.
Common symptoms of skin cancer include asymmetrical moles, a patch of skin with different colors such as brown, black, pink, white, or red, or raised reddish patches on your skin that don't go away and are itchy.
What They Look Like. Melanomas in situ tend to be flat and asymmetric with irregular borders. They can be black, brown, tan, gray or even pink if the person has very fair skin.
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.
Any change in size, shape, color or elevation of a spot on your skin, or any new symptom in it, such as bleeding, itching or crusting, may be a warning sign of melanoma.
How Fast Does Melanoma Grow? Some types of melanoma can grow very quickly, becoming life-threatening in as little as six weeks. If left untreated it can spread to other parts of the body. Nodular melanoma is a highly dangerous form of melanoma that looks different from common melanomas and can grow in just a few weeks.
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.
Nodular melanoma (10-15% of melanomas)
It usually appears as a round, raised lump on the surface of the skin that is pink, red, brown or black and feels firm to touch. It may develop a crusty surface that bleeds easily.
Basal cell carcinomas
Basal cell cancers usually develop on areas exposed to the sun, especially the face, head, and neck, but they can occur anywhere on the body. These cancers can appear as: Flat, firm, pale or yellow areas, similar to a scar.
General symptoms
hard or swollen lymph nodes. hard lump on your skin. unexplained pain. feeling very tired or unwell.
Atypical mole (also called dysplastic nevus).
An atypical mole may look like melanoma but isn't.
Does melanoma hurt? You can have melanoma without feeling any pain or discomfort. For many people, the only sign of this skin cancer is a spot that has some of the ABCDEs of melanoma or a line beneath a nail. Sometimes, melanoma causes discomfort.
Melanoma is a very serious skin cancer characterized by the uncontrolled growth of cells that produce pigment, the substance in skin that produces color. Melanomas may appear suddenly and without warning.
Melanoma often starts as a new spot on your skin, but a mole you already have can turn into melanoma. A spot or mole may get bigger. A spot or mole may have an irregular, not-smooth edge or surface. A spot or mole may change colour such as brown, black, blue, red, pink, white and/or light grey.
Melanomas can develop anywhere on the skin, but they are more likely to start on the trunk (chest and back) in men and on the legs in women.
The first sign of melanoma is often a mole that changes size, shape or color. This melanoma shows color variations and an irregular border, both of which are melanoma warning signs. Melanomas can develop anywhere on your body.
Early melanomas
Stage I: The cancer is smaller than 1 mm in Breslow depth, and may or may not be ulcerated.
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.
