Melanoma Signs and Symptoms

 

In the beginning stages of melanoma, symptoms are often very subtle.

The first warning signs are usually visual; patients rarely experience any pain or discomfort.

Melanoma warning signs are often referred to by the popular “ABCD” acronym. If a mole displays any of the following characteristics, it’s best to consult with a physician for evaluation and testing:

  • Asymmetry. Does the mole have two parts that look very different?
  • Border. Does the mole have an irregular border?
  • Color. Does the mole have different colors, such as tan, brown and black?
  • Diameter. Is the mole larger than 6 mm in diameter?
The first warning signs of skin cancer are usually visual. Checking your moles for changing characteristics is a good practice.

What does malignant melanoma look like?

Some melanomas do not involve an asymmetrical, irregular, unusually colored or excessively large mole. Certain types of melanoma can look like a small brown or black streak underneath a toenail or fingernail, while other types can look like an ordinary bruise that doesn’t heal over time. Just as some melanomas do not display any of the traditional warning signs, it’s also possible for some perfectly healthy moles to have an irregular appearance.

Speak to your dermatologist if you notice any of the following changes to your skin:

  • A mole that’s suddenly different in appearance
  • A small, scaly patch
  • Itchy or tender nodules felt under the skin
  • A mole that’s uneven in color or has a blurred border
  • A bump, sore or rash that does not heal

While the majority of these skin changes aren’t cause for concern, it’s always good to have them looked at by a professional, as early detection is key to an improved outlook for melanoma.

Melanoma on the scalp

Melanoma that grows on the scalp can be a dangerous form of skin cancer, as it’s much harder to detect than melanoma that grows on an unobscured area of the skin. What’s more, this type of melanoma grows at a much faster rate since there are many more blood vessels and tissues to aid this process. Therefore, it’s beneficial to conduct regular scalp skin checks—even more so if you are bald or have thin hair. 

Here’s how to conduct a scalp skin check:

  • Stand in a well-lit room with a handheld mirror.
  • Part a section of your hair and use the mirror to examine your scalp.
  • Look for moles, blemishes and red patches as you inspect your scalp, as these can be indications of melanoma.
  • Continue parting your hair and examining your scalp until you have looked over your entire head.

While it’s helpful to have a friend or family member to assist you with the scalp skin check, this is something you can do on your own. If you see anything suspicious, make note of it and report it to your dermatologist right away.

Understanding late-stage melanoma

With late-stage melanoma, patients may begin to experience certain uncomfortable symptoms. These melanoma symptoms include:

  • Itching
  • Bleeding
  • Oozing and/or crusting
  • Pain and irritation

Because these symptoms may indicate melanoma, they should be immediately discussed with a dermatologist or oncologist who specializes in skin cancer. Regular dermatologist visits can make it much more likely for abnormal moles to be properly detected and diagnosed. Melanoma screenings, such as those performed at Moffitt Cancer Center and at Moffitt’s mobile community Mole Patrol®, can also improve a patient’s chance of early diagnosis, should an abnormality occur.

What are the symptoms of melanoma that has spread?

Metastatic melanoma is cancer that has spread from the skin to another part of the body. It most often spreads to the lymph nodes, brain, bones, liver or lungs, with patients experiencing symptoms based on where it has spread to:

  • Lymph nodes – Swollen or painful lymph nodes or hardened lumps felt under the skin
  • Brain – Headaches or seizures
  • Bones – Fractures or bone pain
  • Liver – Loss of appetite, unexplained weight loss or enlarged liver
  • Lungs – Difficulty breathing or a persistent cough 

It’s also common to experience fatigue and weakness or numbness in your arms or legs.
