What Does A Melanoma Look Like?

Melanoma is a type of skin cancer that develops from melanocytes, the cells that produce pigment in the skin.


It is important to know the symptoms of melanoma so that it can be detected and treated early.


Some common symptoms of melanoma include:

  1. Changes in the shape, size, or colour of an existing mole or the appearance of a new mole.
  2. Asymmetry of a mole, where one half is different from the other half.
  3. Irregular or ragged borders of a mole.
  4. Varied colours or shades within a mole, such as black, brown, or different shades of tan, red, white, or blue.
  5. Moles that are larger than 6 millimeters in diameter (about the size of a pencil eraser).
  6. Itching, bleeding, or crusting of a mole.
  7. Redness or swelling beyond the border of a mole.


It is important to note that not all melanomas follow these typical symptoms, and some may appear differently.

If you notice any unusual changes on your skin or any of these symptoms, it is important to see a skin specialist for evaluation.

What Does A Melanoma Look Like?

Melanoma is a type of skin cancer that can have a variety of appearances, but typically, it appears as an irregularly shaped mole or lesion on the skin.


Some common signs of melanoma include:

  1. Asymmetry: One half of the mole does not match the other half.
  2. Irregular Borders: The mole or lesion has uneven, scalloped, or notched edges.
  3. Varied Colours: The mole or lesion has multiple colors, including black, brown, tan, red, blue, or white.
  4. Diameter: The mole or lesion is larger than 6 millimeters (about the size of a pencil eraser), but melanomas can also be smaller.
  5. Evolving: The mole or lesion has changed in size, shape, or colour, or it is evolving over time.



What is Nodular melanoma?

Nodular melanoma is a type of skin cancer that develops from the pigment-producing cells (melanocytes) in the skin.


It is considered to be one of the most aggressive forms of melanoma because it grows rapidly and can spread to other parts of the body.

Nodular melanoma typically appears as a raised bump on the skin, which may be black, brown, red, or skin-coloured.

It may resemble a mole, but it can grow quickly and often has a smooth or shiny surface. Unlike other types of melanoma, nodular melanoma may not have the typical irregular borders and colour variations that are often associated with melanoma.


Nodular melanoma is usually diagnosed by performing a biopsy, in which a small sample of the suspicious area is removed and examined under a microscope. If it is determined to be nodular melanoma, treatment may involve surgical removal of the tumor, as well as additional therapies such as radiation or chemotherapy to target any cancer cells that may have spread to other parts of the body.


It is important to note that early detection and treatment of nodular melanoma is crucial for a positive outcome.

If you notice any unusual changes on your skin, such as a new or changing mole, it is important to see a dermatologist for evaluation.

When we think about sunny days, beach outings, backyard barbecues, or even a casual stroll in the park, we often picture warmth, happiness, and the golden glow of sunlight. Yet behind this idyllic imagery lies a silent threat: ultraviolet (UV) radiation. Prolonged and unprotected exposure to UV rays is the leading cause of skin cancer, the most common cancer worldwide. While sunscreen plays a well-known role in defense, one equally vital yet sometimes overlooked method is wearing protective clothing.

Australia holds the unenviable title of having one of the highest rates of skin cancer in the world. With our sun-soaked climate and love of the great outdoors, it’s no wonder that skin health has become a national priority. And yet, too many people still overlook the signs their skin is sending them—signs that could spell the difference between early intervention and a serious health battle. Whether you’re checking your own skin at home or preparing for a visit to a specialist, understanding what to look for and when to act is crucial.

We all have them—freckles, spots, and moles that seem harmless. But what if one of those seemingly innocent marks holds the early signs of something more serious? Every year, thousands of people are diagnosed with skin cancer, and many of those cases could have been caught earlier—perhaps even prevented—through routine skin checks. In Australia, where sun exposure is a daily reality, the importance of regular skin checks cannot be overstated.

Skin cancer is one of the most common cancers globally, and among its many forms, melanoma is the most aggressive. Within the melanoma category, nodular melanoma stands out as one of the most dangerous and fast-growing types. Because it doesn’t always follow the usual warning signs of skin cancer, it's crucial to understand what it looks like, how it behaves, and what risk factors contribute to its development.
