Melanoma is the most serious type of skin cancer. It can be deadly if not detected and treated early. Therefore, it's essential to be aware of the signs and symptoms of melanoma and to get regular skin checks by a dermatologist.
In this article, we'll discuss what melanoma looks like and how to spot it early. We'll also provide information on the risk factors for melanoma and how to protect yourself from this deadly disease.
Melanoma can appear anywhere on the body, but it's most often found on areas that are exposed to the sun, such as the back, legs, and arms. It can also occur on the palms of the hands, soles of the feet, and under the nails.
What Does Melanoma Look Like
Melanoma can appear in various forms and colors, but there are some common signs to watch out for:
- Asymmetrical shape
- Irregular borders
- Multiple colors
- Diameter larger than 6 millimeters
- Evolving size or shape
- Bleeding or crusting
- Itching or tenderness
- New or changing mole
- Dark streaks or spots
If you notice any of these signs on your skin, it's important to see a dermatologist right away for further evaluation.
Asymmetrical Shape
One of the key signs of melanoma is an asymmetrical shape. This means that the mole or lesion is not symmetrical when you draw a line down the middle.
- Irregular halves: The two halves of the mole or lesion do not match in size, shape, or color.
- Notched or scalloped borders: The edges of the mole or lesion are not smooth and even, but rather have notches or scallops.
- Vague or poorly defined borders: The edges of the mole or lesion blend into the surrounding skin, making it difficult to see where the mole or lesion begins and ends.
- Asymmetry in color or texture: Different parts of the mole or lesion may have different colors or textures.
If you notice any asymmetry in a mole or lesion on your skin, it's important to see a dermatologist right away for further evaluation.
Irregular Borders
Another common sign of melanoma is irregular borders. This means that the edges of the mole or lesion are not smooth and even, but rather have notches, scallops, or indentations.
- Notched or scalloped borders: The edges of the mole or lesion have small notches or scallops, giving it a jagged appearance.
- Indented or wavy borders: The edges of the mole or lesion are indented or wavy, creating an uneven or irregular outline.
- Blurred or poorly defined borders: The edges of the mole or lesion blend into the surrounding skin, making it difficult to see where the mole or lesion begins and ends.
- Satellite lesions: Small, additional moles or lesions may appear around the main mole or lesion, which can be a sign of melanoma.
If you notice any irregular borders on a mole or lesion on your skin, it's important to see a dermatologist right away for further evaluation.
Multiple Colors
Melanoma can exhibit a variety of colors, including black, brown, tan, red, pink, white, or blue. It's important to note that not all melanomas are black or brown. In fact, some melanomas may be predominantly pink, red, or white.
The presence of multiple colors within a single mole or lesion can be a sign of melanoma. This is because melanoma cells can produce different types of pigment, leading to a mix of colors within the lesion.
Here are some specific color patterns that may be associated with melanoma:
- Black and brown: This is the most common color combination for melanoma, but it can also be seen in benign moles.
- Red, white, and blue: This combination of colors is often seen in amelanotic melanoma, a type of melanoma that lacks pigment.
- Pink or red: This color is often seen in superficial spreading melanoma, a type of melanoma that spreads horizontally across the skin.
- Dark brown or black with lighter patches: This color pattern is often seen in nodular melanoma, a type of melanoma that forms a raised bump on the skin.
It's important to note that multiple colors alone do not necessarily indicate melanoma. However, if you notice any changes in the color of a mole or lesion, or if it exhibits multiple colors, it's important to see a dermatologist right away for further evaluation.
Diameter Larger Than 6 Millimeters
One of the key signs of melanoma is a diameter larger than 6 millimeters (about the size of a pencil eraser). However, it's important to note that not all melanomas are larger than 6 millimeters. Some melanomas can be smaller, especially in their early stages. Additionally, some benign moles can be larger than 6 millimeters.
Therefore, it's important to pay attention to other signs of melanoma, such as asymmetry, irregular borders, multiple colors, and changes in size or shape. If you notice any of these signs, even if the mole or lesion is smaller than 6 millimeters, it's important to see a dermatologist right away for further evaluation.
Here are some things to keep in mind about the diameter of melanoma:
- Early melanomas can be very small: Some melanomas can be as small as 2 millimeters or less in diameter when they are first detected.
- Melanomas can grow quickly: Melanomas can grow rapidly, so it's important to monitor any suspicious moles or lesions for changes in size.
- Size is not the only factor: While diameter is an important factor to consider, it's important to remember that other signs of melanoma, such as asymmetry, irregular borders, and multiple colors, are also important.
If you have any concerns about a mole or lesion on your skin, regardless of its size, it's always best to see a dermatologist for further evaluation.
Evolving Size or Shape
One of the most important signs of melanoma is a mole or lesion that is evolving in size or shape. This can be a sign that the mole or lesion is cancerous and growing. However, it's important to note that not all moles or lesions that change in size or shape are cancerous. Some benign moles can also change in size or shape over time.
Therefore, it's important to pay attention to other signs of melanoma, such as asymmetry, irregular borders, and multiple colors. If you notice any of these signs, along with a change in size or shape, it's important to see a dermatologist right away for further evaluation.
Here are some things to keep in mind about evolving size or shape in melanoma:
- Melanomas can grow quickly: Melanomas can grow rapidly, so even a small change in size or shape can be a sign of cancer.
- Melanomas can change shape: Melanomas can change shape, becoming more asymmetrical or developing irregular borders.
- Not all changes are cancerous: Some benign moles can also change in size or shape over time. However, it's important to have any suspicious changes evaluated by a dermatologist.
If you notice any changes in the size or shape of a mole or lesion on your skin, regardless of how small the change may seem, it's always best to see a dermatologist for further evaluation.
Bleeding or Crusting
Bleeding or crusting of a mole or lesion is a common sign of melanoma. This can occur when the melanoma breaks down the surrounding skin tissue, causing it to bleed or form a crust.
- Spontaneous bleeding: A melanoma may start to bleed without any apparent cause, such as scratching or picking.
- Bleeding after minor trauma: A melanoma may bleed after minor trauma, such as accidentally bumping or scratching it.
- Persistent crusting: A melanoma may develop a crust that does not heal and may continue to bleed or ooze.
- Change in the color of the crust: The crust on a melanoma may change color, becoming darker or black.
Bleeding or crusting of a mole or lesion is not always a sign of melanoma. However, it is important to see a dermatologist right away if you notice any bleeding or crusting, especially if it is accompanied by other signs of melanoma, such as asymmetry, irregular borders, multiple colors, or changes in size or shape.
Itching or Tenderness
Itching or tenderness of a mole or lesion can be a sign of melanoma. This can occur when the melanoma cells irritate the surrounding skin tissue, causing inflammation and discomfort.
- Persistent itching: A melanoma may cause persistent itching that does not go away with scratching.
- Tenderness to the touch: A melanoma may become tender or painful to the touch.
- Change in sensation: The area around a melanoma may feel numb or tingly.
- Burning or stinging sensation: A melanoma may cause a burning or stinging sensation.
Itching or tenderness of a mole or lesion is not always a sign of melanoma. However, it is important to see a dermatologist right away if you notice any itching or tenderness, especially if it is accompanied by other signs of melanoma, such as asymmetry, irregular borders, multiple colors, or changes in size or shape.
New or Changing Mole
The development of a new mole or a change in an existing mole can be a sign of melanoma. Melanomas can develop anywhere on the skin, but they are most commonly found on areas that are exposed to the sun, such as the back, legs, and arms.
It's important to pay attention to any new moles or changes in existing moles, especially if you have a history of sun exposure or a family history of melanoma.
Here are some things to look for when examining your moles:
- New moles: Any new mole that appears, especially after the age of 20, should be examined by a dermatologist.
- Changes in size: A mole that is growing in size, especially if it is growing rapidly, should be examined by a dermatologist.
- Changes in shape: A mole that is becoming more asymmetrical or developing irregular borders should be examined by a dermatologist.
- Changes in color: A mole that is developing multiple colors or a mole that is changing color, especially if it is becoming darker, should be examined by a dermatologist.
- Changes in texture: A mole that is becoming thicker, scaly, or crusty should be examined by a dermatologist.
If you notice any new moles or changes in existing moles, it's important to see a dermatologist right away for further evaluation.
Dark Streaks or Spots
Dark streaks or spots on the nails can be a sign of melanoma. This is known as subungual melanoma, and it occurs when melanoma cells grow under the nail.
- Brown or black streaks: Subungual melanoma often appears as a brown or black streak or band on the nail.
- Dark spots: Subungual melanoma can also appear as a dark spot or spots on the nail.
- Changes in nail color: The nail may become darker or black in color.
- Changes in nail shape: The nail may become thickened, ridged, or brittle.
Dark streaks or spots on the nails can also be caused by other conditions, such as fungal infections or trauma to the nail. However, it's important to see a dermatologist right away if you notice any dark streaks or spots on your nails, especially if you have other risk factors for melanoma, such as a history of sun exposure or a family history of melanoma.
