Red Flag #: Swollen Lymph Nodes
If melanoma spreads, it often goes to the lymph nodes first, says Melinda L. Yushak, M.D., assistant professor of hematology and medical oncology at Emory University School of Medicine in Atlanta. The cancer cells will first travel to the nodes closest to the original tumor, she says. Lymph nodes are located throughout your entire body, but large clusters are found in the neck, underarms, chest, abdomen, and groin. If the cancer has made its way to the lymph nodes, it usually wont be painful, but theyll feel swollen or even hard to the touch, Dr. Zaba says.
Is Melanoma Always Malignant
While malignant, these are unlikely to spread to other parts of the body if treated early. They may be locally disfiguring if not treated early. A small but significant number of skin cancers are malignant melanomas. Malignant melanoma is a highly aggressive cancer that tends to spread to other parts of the body.
Your May Experience Side Effects
The vast majority of patients who receive immunotherapy will have little to no side effects, says Dr. Betof Warner. Its a huge change from the days when patients were on chemotherapy and were profoundly nauseous, vomiting, and had suppressed immune systems. Still, side effects can occur, including flu-like fever, aches, fatigue, and nausea. The risk of side effects with targeted therapy is a bit higher, but Dr. Betof Warner says they tend to disappear faster. These can include rashes, headaches, joint pain. And more seriously, kidney failure, bleeding, and heart and liver problems.

The Visible Scars Of Melanoma
Unfortunately, people with metastatic disease might be going from treatment to treatment to treatment for years, says Smelko, but the melanoma world has recently exploded with a lot of great new treatments and more on the way. People are seeing great results and living for years. Its very promising. Those therapies include new biologic treatments that target different pathways of melanoma cell growth for advanced melanomas, as well as several different immune therapies and still-investigational combinations of systemic agents for melanomas that appear to have a worse prognosis, Cohen notes.Surviving melanoma can mean living with visible scars. In Brossarts case, Cohen and Contreras removed the melanoma, leaving a wound about the size of a silver dollar. Cohen then repaired this surgical defect with a large flap that mobilized skin from her lateral cheek all the way to her temple. The surgery to close the wound left a large triangular scar on her face that went from the outside corner of her left eye to the side of her nose and down to her left jaw.
It was scary to look in the mirror, recalls Brossart, who works at an elementary school in Castle Rock, Colorado. I wondered if I was ever going to be able to walk down the street and not stop traffic.
They did a fabulous job, she says now. I do see a scar when I look in the mirror. I think itll always be there, but it becomes the new normal. You look in the mirror, its there, and you dont think about it anymore.
Red Flag #: Headaches Or Visual Changes
Just like the liver, not everyone will notice symptoms of melanoma spreading to the brain. But when symptoms do show up, its usually in the form of headaches, problems with eyesight, paralysis on one side of the body, or seizures. If someone simply has a headache, that doesnt mean they have advanced stage melanoma, Dr. Yushak says. But if its a headache thats not going away after a week, and you never have headaches, then thats something that definitely needs to be checked out.

Diagnosis Of Metastatic Melanoma
Your care team may use several tests to diagnose metastatic melanoma.
If theres evidence of a primary tumor, a biopsy may be taken. For this, a small section of suspected cancerous skin is removed with a razor, scalpel or small punch tool. The removed tissue is examined under a microscope to determine whether its melanoma.
Additional tests are needed to determine whether the cancer is metastatic melanoma, or if theres no visible primary tumor. To test for metastatic melanoma, or melanoma that has spread to lymph nodes or distant parts of the body, your care team may perform the following tests.
- Lymph node mapping and sentinel lymph node biopsy : Your doctor may perform a physical exam of your lymph nodes and check for swelling or physical masses. If no tumors are found , an SLNB may be done. For an SLNB, a radioactive dye is injected to locate the primary tumor. Then, the doctor will remove the lymph nodes that the dye traveled to and check them for melanoma.
- Computed tomography scan, positron emission tomography scan, magnetic resonance imaging scan or ultrasound exam: Each of these scans is a noninvasive way to look inside your body and check for tumors.
- Blood chemistry studies: Cancer may cause elevated or abnormal levels of certain substances in your blood. A laboratory test can identify if your blood chemistry shows signs of a cancerous tumor.
Risk Factors For Metastatic Melanomas
You cannot get metastatic melanoma without first having melanoma, though the primary melanoma may be so small its undetectable. Major risk factors for melanomas include:
- Light skin, light-colored hair or light-colored eyes
- Skin prone to burning easily
- Multiple blistering sunburns as a child
- Family history of melanoma
- Frequent exposure to sun or ultraviolet radiation
- Certain genetic mutations
- Exposure to environmental factors, such as radiation or vinyl chloride
Other factors have been connected with increased metastasis. In a 2018 study in the Anais Brasileiros de Dermatologia and a 2019 study in the Journal of the National Cancer Institute, the following factors were associated with higher levels of metastasis:
- Male gender
- Primary tumor thickness of more than 4 mm
- Nodular melanoma, which is a specific subtype that a care team would identify
- Ulceration of the primary tumor

Red Flag #: Bone Pain Or Fractures
The bones are considered a late-stage site of melanoma metastasestypically, it doesnt spread to the bones until its already spread to another area of the body first. Melanoma can cause pain in the bones where its spread, and some peoplethose with very little body fat covering their bonesmay be able to feel a lump or mass. Metastatic melanoma can also weaken the bones, making them fracture or break very easily. This is most common in the arms, legs, and spine. If you feel any sharp, sudden, or new pains that wont go away, talk to your doctor.
Treatment Of Malignant Melanoma In Dogs
While treatment of malignant melanoma depends on the progression of the disease, surgery, radiation, and chemotherapy are strongly suggested. However, none of the treatments are an actual cure as the melanoma grows back in many cases.
As long as the cancer has not spread too far, surgical removal of the melanoma is always the first part of the treatment plan. This is usually a simple surgery, depending on the location, and only has slight risks (less than not having the surgery. The veterinarian removes the melanoma and a large area of tissue around it to improve the chance of survival.
This treatment is done only in cases where there is still a small risk of tumor regrowth. However, it has not shown to add much time to the prognosis of survival.

Predictive Factors For Overall Survival
We analyzed the potential association between several factors and survival using univariate Cox regression of overall survival . Intriguingly, of factors in the primary tumor, increased levels of tumor-infiltrating lymphocytes showed a trend toward improved survival in patients with brain metastasis. Several clinical factors were found to be significantly associated with overall survival in patients with brain metastasis by univariate analysis . Factors associated with shorter overall survival included male sex, cerebellar involvement, higher number of metastatic brain tumors, concurrent presence of adrenal metastasis, or treatment with whole-brain radiation therapy. Factors associated with longer overall survival were treatment with craniotomy, stereotactic radiosurgery, or anti-PD-1 antibody therapy after initial diagnosis of brain metastasis.
Table 4 Univariate Cox regression analysis of association of various clinical factors with overall survival in melanoma patients with brain metastasis
Multivariate analysis of all eight factors revealed cerebellar involvement, craniotomy, and adrenal involvement as independently predictive of survival . There was trend toward significance for treatment with anti-PD-1 antibody .

A Sense Of Possibility
The first checkpoint inhibitor drug, ipilimumab, was approved by the US Food and Drug Administration in March 2011 for the treatment of melanoma that had spread or that could not be treated surgically. Compared with a melanoma vaccine, itself a new therapeutic approach being trialled, the drug significantly improved survival rates. Although it worked in only around one in five patients, the benefits in those patients were dramatic, Larkin says. We really had a sense then of the possibilities.
Ipilimumab was followed by pembrolizumab in September 2014, and nivolumab just three months later. All of these, and newer checkpoint inhibitors, are now in widespread use, although theyre expensive for patients, particularly in countries without public health insurance schemes. A course of intravenous checkpoint inhibitor therapy can cost US$150,000250,000 per year.
The most spectacular results so far with checkpoint inhibitor therapy have come from trials combining two different checkpoint inhibitors, such as ipilimumab and nivolumab. Larkin and Wolchok were both involved in the CheckMate 067 study, which began in July 2013 and compared ipilimumab alone with nivolumab alone, and with ipilimumab plus nivolumab in 945 people with advanced untreated melanoma.
Theres also evidence that patients with cancers caused by a certain genetic condition called mismatch repair deficiency may actually respond better to checkpoint inhibitors, regardless of their cancer type.

General Survival Rate Information
Five-year and ten-year survival rates tell you what percent of people live at least five years and ten years, respectively, after the cancer is found.
Statistics on the survival rates for people with melanoma are based on annual data from past cases and over multi-year timeframes.
Because treatments for melanoma are more successful in early stages, it is informative to look at survival rates based on stage and stage subgroups rather than on the cancer as a whole.
It is important to remember that survival rates do not predict an individuals survival. Every person and every case are different, and many factors contribute to an individuals survival. Its also important to remember that new and successful treatments have emerged over the last few years, and survival rates have increased in Stage III and Stage IV melanoma.
Diagnosis Of Malignant Melanoma In Dogs
Diagnosis is pretty easy if you are able to get a veterinary oncologist or one who specializes in skin diseases. Most veterinarians can do a physical examination and confirm the diagnosis right away, but will not confirm it until blood tests and a biopsy are done. During the examination, be sure to tell the veterinarian as much as you know about the issue and if you have given your dog any medication, prescription or otherwise. The examination includes a complete skin and haircoat analysis, reflexes, body temperature, weight, blood pressure, heart rate, respirations, breath sounds, pupil reaction time, and oxygen level.
Laboratory testing includes a complete blood count , serum analysis, platelet count, glucose level, blood urea nitrogen , liver panel, packed cell volume , and a urinalysis. A skin scraping or a fine needle biopsy will be gathered for microscopic analysis. Chest films , lymph node aspiration, and possibly a CT scan with contrast dye will all be used to stage the disease. There are four stages, as mentioned earlier.

How Can Melanoma Spread To The Brain
While melanoma normally begins in the skin, cancer cells sometimes grow and break away from the place where the cancer began. The cells that break away often travel to nearby:
Once in the blood or lymph , the melanoma cells often travel to the lungs, liver, spleen, or brain.
Cancer cells growing bigger than normal cells
Cancer cells can grow, break off, and spread.
Symptoms Of Metastatic Melanomas
Melanoma usually is found in early stages, before its become metastatic. If you notice any abnormal moles or discolorations on your skin, dont hesitate to reach out to your doctor. This is especially important for those with many risk factors. Melanoma is more treatable at early stages, so early identification may prevent metastatic melanoma from developing.
Though a primary tumor is typically found, its possible that metastatic melanoma is detected elsewhere in the body and causes symptoms without any signs of a primary tumor.
Metastatic melanoma symptoms and signs may include:

Whats 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. Its usually better if the cancer has only spread to distant parts of the skin and lymph nodes instead of other organs.
A Hopeful Future For Treating Melanoma
With a multidisciplinary team like we have at Roswell Park, were able to make better decisions regarding your care. Our dedicated team includes surgeons, dermatologists and oncology specialists who discuss the details of each case. Puzanov also notes that a team with so many different skills can help patients manage any side effects of their treatment. He estimates that nearly 50% of patients can enroll in new clinical trials, some of which are offered only at comprehensive cancer centers like Roswell Park.
We are starting to cure melanoma, and its very exciting, Puzanov adds happily. Were doing great things and hopefully people wont have to die from this diagnosis anymore. With new clinical trials, treatments and approaches, melanoma is quickly becoming a disease that can be managed and lived with as opposed to one that might be fatal.

Youll Have A Team On Your Side
Once your physician finds out where your stage 4 melanoma has spread, youll be referred to more doctors for treatment. If your tumors are operable, youll be referred to a surgical oncologist, who will perform the surgery. Youll also have a medical oncologist, who will determine your ideal type of treatment, or combination of treatments. Treatments for stage 4 melanoma include immunotherapy, targeted drugs, chemotherapy, and radiation.
Red Flag #: Chest Pain And Trouble Breathing
Melanoma is also known to spread to the lungs, though Dr. Zaba notes that most people dont experience noticeable symptoms in the lungs until a tumor has gotten pretty large. A cough that just wont quit or recurring chest infections can signal that the cancer has traveled to the lungs, Dr. Polsky says. Shortness of breath or trouble breathing can also be a red flag.

When Melanoma Can’t Be Cured
If your cancer has spread and it is not possible to cure it by surgery, your doctor may still recommend treatment. In this case, treatment may help to relieve symptoms, might make you feel better and may allow you to live longer.Whether or not you choose to have anti-cancer treatment, symptoms can still be controlled. For example, if you have pain, there are effective treatments for this. General practitioners, specialists and palliative care teams in hospitals all play important roles in helping people with cancer.
The 4 Stages Of Melanoma
Two main things determine the stage of melanoma: The thickness or depth of the tumor and how far it has spread when its diagnosed, explains David Polsky, M.D., dermatologist at NYU Langone Medical Center in New York City. In stages 0, 1, and 2, the melanoma is limited to the skin. In stage 3, its spread to the lymph nodes, small structures throughout your body that help filter fluids and fight infection. In the most advanced stage, stage 4, melanoma cells have broken away from the original tumor, traveled through the body and formed a new tumor somewhere else.

It Usually Starts With Suspicious Spot
Maybe you noticed a mole that stood out from the rest . Its edges were irregular, maybe it was asymmetrical in shape, unevenly pigmented, noticeably large , or rapidly changing . These are the spots that concern dermatologists. If you had one, your doc did a biopsy on your own ugly duckling. During this in-office procedure, your doctor either shaved off a layer of your mole, punched it out with a hole-punch-like tool, or removed it with surgical excision, along with a margin of healthy skin to check for wandering cancer cells.
Waiting Even Days To Remove Melanoma Can Be Deadly
Researchers analyzed data from more than 153,000 American adults diagnosed with stage 1 to 3 melanoma between 2004 and 2012.
No matter what stage their cancer was, those who waited more than 90 days for surgical treatment were more likely to die.
And postponing surgery for more than 29 days led to lower survival rates for patients with stage 1 melanoma, though not for those with stage 2 or 3.
Compared to patients who were treated within 30 days, patients with stage 1 melanoma were 5 percent more likely to die when treated between 30 and 59 days. Their risk of death rose 16 percent when treated between 60 and 89 days 29 percent when treated between 91 and 120 days and 41 percent when treated after 120 days.
Patients who put off their treatment tended to be older men who also had other health problems.
The Cleveland Clinic study was published online recently in the Journal of the American Academy of Dermatology.
“The ideal timing for melanoma treatment, predominantly surgery, had yet to be determined — until now,” said primary investigator Dr. Brian Gastman. He is director of melanoma surgery at the Cleveland Clinic in Ohio.
Melanoma is on the rise in the United States. Nearly 162,000 new cases are expected to be diagnosed this year.
