How do I know if I have melanoma?

The Warning Signs of Melanoma


Development of a New Spot

A new mole or sore can be suspicious. If you have noticed a new spot on your skin, you should have it checked out just to be safe.

Change in Appearance

Melanoma is known to evolve quickly. The most noticeable changes are often in size: if the mole is over a quarter inch in diameter,it may be indicative of melanoma. Also common are changes in shape and color. Melanoma is usually black or brown but can have shades of pink, red, or white, or even blue.


Itching or Tenderness

In some cases, your mole may begin to itch or even feel painful. This is often accompanied by scaling, oozing, or bleeding.

So what exactly causes melanoma?

Melanoma is Tied to Sun Exposure & Changes within Your Genes

Sunlight Exposure

While other skin cancers are associated with long-term exposure to sunlight, melanoma is caused by brief but intense exposure to UVA and UVB rays.

Changes in Your Genes

The DNA within the cells that make up a mole control whether it becomes cancerous. Mutations within those genes, often occurring due to damage from sun exposure, can cause the cells to malfunction, leading to melanoma.

What does it mean if you've been diagnosed with melanoma?

Is melanoma difficult to diagnose?

A Visual Exam & Biopsy Allow the Doctor to Closely Evaluate the Spot

Melanoma can be diagnosed by your doctor, who will usually perform a visual exam first. If they see something they think requires a closer evaluation, they will perform a biopsy, which is the removal of some or all of the tissue from the area. They will then evaluate the tissue under a microscope to determine whether it is cancerous. Depending on the results, they can then recommend the best course of treatment.
