What is Melanoma?

Melanoma is a type of skin cancer. It’s less common than other skin cancers, such as basal cell carcinoma and squamous cell carcinoma, however, it’s more dangerous because it is more likely to spread to other organs.

Your skin gets its unique color from “melanocytes” (cells that produce a pigment called melanin). Melanocytes also make extra pigment in response to sunlight. That’s why your skin may darken after spending time in the sun.

Melanoma Signs

Melanoma cancer begins in the melanocytes. As these cancerous cells multiply, they can grow into a small mass (tumor) on your skin. Warning signs of melanoma include:

  • A new mole, spot, lump or blemish
  • An existing spot that has changed size, shape or color
  • An existing spot that turns painful or itchy
  • An existing spot that begins to ooze or bleed
  • A sore that won’t heal

Where Does Melanoma Occur?

Melanoma usually occurs on parts of the skin with significant sun exposure. But it can occur anywhere on the body, even in hidden areas. These include the bottom of your foot, under a fingernail, between your toes or inside your mouth.

Because melanoma can be sneaky—and serious—doctors recommend you have regular skin exams. Your primary care doctor or a dermatologist can check your skin during routine medical visits. They can check areas that are hard for you to see, like your scalp and back.

Between medical exams, you should regularly check your own skin. When you’re familiar with the look and feel of your skin, you can identify suspicious changes to moles, freckles and other marks.
