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.

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.

Skin cancer is the most prevalent form of cancer globally, with millions of new cases diagnosed each year. Despite its high incidence, there remains a concerning question among some individuals: "Can I leave my skin cancer alone?" Addressing this question requires a comprehensive understanding of the types of skin cancer, their potential progression if untreated, and the critical importance of early detection and treatment.

Sunscreen is one of the most effective tools in protecting your skin from the harmful effects of ultraviolet (UV) radiation. Whether you’re heading to the beach, going for a walk, or just running errands, wearing sunscreen daily is essential for maintaining healthy, youthful skin and reducing the risk of sun damage and skin cancer. But what exactly are the benefits of using sunscreen, and how often should you reapply it to ensure maximum protection?

Many people love the sun-kissed glow of a tan, but also understand the risks of prolonged sun exposure. Sunscreen is widely recommended as a protective measure against sunburn and skin damage, but does it completely prevent tanning? If you apply sunscreen correctly, can you still achieve that bronzed look? We will explore the science behind tanning, how sunscreen works, and whether you can safely tan while wearing it.

The sun is a source of life, providing warmth and essential vitamin D. However, prolonged and unprotected exposure to ultraviolet (UV) radiation poses serious risks to skin health. From sunburn and premature aging to an increased likelihood of skin cancer, UV rays can cause irreversible damage. This is where sunscreen, specifically those with high Sun Protection Factor (SPF), plays a crucial role in safeguarding skin health.

Sunscreen is a vital part of skin protection, shielding against the harmful effects of ultraviolet (UV) radiation from the sun. There are two main types of sunscreen: mineral-based (also known as physical sunscreen) and chemical-based. While both provide sun protection, they differ significantly in their composition, how they function, and their overall impact on the skin and environment.
