What Do the Symptoms of Stage 4 Melanoma Look Like?

What does a stage 4 diagnosis for melanoma mean?

Stage 4 is the most advanced phase of melanoma, a serious form of skin cancer. This means the cancer has spread from the lymph nodes to other organs, most often the lungs. Some doctors also refer to stage 4 melanoma as advanced melanoma.

To diagnose for stage 4 melanoma, your doctor will conduct:

  • blood tests, to look at blood count and liver function
  • scans, such as ultrasound and imaging, to look at how the cancer has spread
  • biopsies, to remove a sample for examination
  • multidisciplinary team meetings, or meetings with a team of skin cancer specialists

Sometimes melanoma can reoccur after it’s been removed.

Melanoma statistics
The rate for melanoma cases has risen in the last 30 years. In 2016, 76,380 people received a melanoma diagnosis.

Your doctor will look at where the cancer has spread and your elevated serum lactate dehydrogenase (LDH) level to determine how far into stage 4 the cancer is. Read on to find out what the symptoms of stage 4 melanoma look like.

What do stage 4 tumors look like?

A change to an existing mole or normal skin can be the first sign that the cancer has spread. But the physical symptoms of stage 4 melanoma aren’t the same for everyone. A doctor will diagnose stage 4 melanoma by looking at the primary tumor, the spread to nearby lymph nodes, and whether the tumor has spread to different organs. While your doctor won’t base their diagnosis only on what your tumor looks like, part of their diagnosis involves looking at the primary tumor.

Tumor matting

This symptom of stage 4 melanoma is easier to feel than it is to see. When melanoma spreads to nearby lymph nodes, those nodes may become matted, or joined together. When you press on the matted lymph nodes, they will feel lumpy and hard. A doctor, checking for advanced melanoma, may be the first person to detect this symptom of stage 4 melanoma.

Tumor size

The size of the tumor isn’t always the best indicator of skin cancer staging. But the American Joint Commission on Cancer (AJCC) reports that stage 4 melanoma tumors tend to be thicker — more than 4 millimeters deep. However, because stage 4 melanoma is diagnosed once the melanoma has spread to distant lymph nodes or to other organs, the size of the tumor varies from person to person. Additionally, treatment may shrink the tumor, but the cancer can still metastasize.

Tumor ulceration

Some skin cancer tumors develop an ulceration, or a break in the skin. This opening can begin as early as stage 1 melanoma and can continue into more advanced stages. If you have stage 4 melanoma, your skin tumor may or may not be broken and bleeding.  

According to the American Cancer Society, melanomas that have ulcerations indicate a lower survival rate.

Self-exam

You can also follow the ABCDEs to examine yourself for melanoma. Look for:

  • asymmetry: when the mole is uneven
  • border: an irregular or poorly defined border
  • color: a variation of color on the mole
  • diameter: melanomas are usually the size of pencil erasers or larger
  • evolving: a change in the shape, size, or color of the mole or lesion

Talk to your doctor if you notice a new mole or skin lesion on your body, especially if you’ve previously been diagnosed with melanoma.

Where else does melanoma spread to?

When melanoma advances to stage 3, it means the tumor has spread to the lymph nodes or the skin around the primary tumor and lymph nodes. In stage 4, the cancer has moved to other areas far beyond the lymph nodes, like your internal organs. The most common places melanoma spreads to are the:

  • lungs
  • liver
  • bones
  • brain
  • stomach, or abdomen

These growths will cause different symptoms, depending on which areas it has spread to. For example, you may feel breathless or constantly cough if the cancer has spread to your lungs. Or you may have a long-term headache that won’t go away if it has spread to your brain. Sometimes the symptoms for stage 4 melanoma may not appear for many years after the original tumor was removed.

Talk to your doctor if you’re feeling new pains and aches or symptoms. They’ll be able to help diagnose the cause and recommend treatment options.

How do you treat stage 4 melanoma?

The good news is that even stage 4 melanoma can be treated. The sooner the cancer is found, the sooner it can be removed — and the higher your chances are for recovery. Stage 4 melanoma also has the most treatment options, but these options depend on:

  • where the cancer is
  • where the cancer has spread
  • your symptoms
  • how advanced the cancer has become
  • your age and overall health

How you respond to treatment also affects your treatment options. The five standard treatments for melanoma are:

  • surgery: to remove the primary tumor and affected lymph nodes
  • chemotherapy: a drug treatment to stop growth of cancer cells
  • radiation therapy: the application of high-energy X-rays to inhibit growth and cancer cells
  • immunotherapy: treatment to boost your immune system
  • targeted therapy: the use of drugs or other substances to attack cancer drugs

Other treatments may also depend on where the cancer has spread to. Your doctor will discuss your options with you to help map out a treatment plan.

Clinical trials

Self-care
Prevention involves protecting yourself from the sun. You can protect your skin by covering it with clothing, high SPF sunscreen, and sunglasses. Your sunscreen should protect against UVB and UVA. Apply it 15 to 20 minutes before going out and stay out of direct sunlight, especially from 11 a.m. to 3 p.m.

Many of today’s treatments for cancer were based on early clinical trials. You may want to participate in a clinical trial for melanoma, especially if it’s melanoma that can’t be removed by surgery. Each trial will have its own criteria. Some require people who have not yet received treatment while others test for new ways to reduce cancer side effects. You can find clinical trials through the Melanoma Research Foundation or the National Cancer Institute.

What’s the outlook for stage 4 melanoma?

Once the cancer spreads, locating and treating the cancerous cells becomes more and more difficult. You and your doctor can develop a plan that balances your needs. The treatment should make you comfortable, but it should also seek to remove or slow cancer growth. The expected rate for deaths related to melanoma is 10,130 people per year. The outlook for stage 4 melanoma depends on how the cancer has spread. It’s usually better if the cancer has only spread to distant parts of the skin and lymph nodes instead of other organs.

Survival rates

In 2008, the 5-year survival rate for stage 4 melanoma was about 15–20 percent, while the 10-year survival rate was around 10–15 percent. Keep in mind that these number reflect the available treatments at the time. Treatments are always advancing, and these rates are only estimates. Your outlook also depends on your body’s response to the treatment and other factors such as age, location of the cancer, and if you have a weakened immune system.

Getting support

A cancer diagnosis of any type can be overwhelming. Learning more about your condition and treatment options can help you feel more in control of your future. Also, informing your friends and family about each step of your journey may also help as you progress through your treatment.

Talk to your doctor about your outlook and potential clinical trials, if you’re a suitable candidate. You can also reach out to local community support groups to share your experience and learn about how other people overcame similar challenges. The American Melanoma Foundation has a list of melanoma support groups across the country.
