Malignant melanoma, the most dangerous type of skin cancer, can often be successfully managed when caught early. Treatment depends on many factors including how far the disease has spread, where it is located in the body, and the overall health of the person diagnosed. While doctors use well-established surgical methods approved by medical organizations, researchers are also testing new therapies in clinical trials that may offer hope for better outcomes, especially for those with advanced disease.

How Treatment Decisions Are Made for Melanoma

When someone receives a diagnosis of malignant melanoma, the first step is to understand what the disease looks like in that particular person. This means figuring out how deeply the melanoma has grown into the skin, whether it has reached nearby lymph nodes (small bean-shaped organs that are part of the immune system), and whether it has traveled to other parts of the body like the liver, lungs, bones, or brain. This process is called staging, and it plays a huge role in deciding which treatment path to follow.^[1][3]

The goal of treatment varies depending on the stage. For early-stage melanoma, the aim is usually to remove the cancer completely and prevent it from coming back. For more advanced melanoma that has spread, treatment focuses on shrinking the tumors, slowing down the disease, controlling symptoms, and helping the person live longer and feel better. Doctors also consider the person’s age, general health, and personal preferences when planning treatment.^[11][12]

Another important factor is the thickness of the melanoma. Thicker melanomas are generally more serious because they are more likely to spread. If the melanoma has broken through the top layer of skin, a condition called ulceration, this also increases the risk. Doctors measure these features under a microscope after taking a small sample of the suspicious skin, a procedure called a biopsy.^[6][11]

Treatment planning is not a one-size-fits-all process. Some people may need only surgery, while others may benefit from a combination of surgery and additional treatments like medicines or radiation. The medical team, which often includes surgeons, skin doctors (dermatologists), cancer specialists (oncologists), and nurses, works together to create a plan tailored to each person’s unique situation.^[10]

Surgery: The Main Treatment for Melanoma

Surgery is the cornerstone of melanoma treatment, especially when the disease is detected early. The most common surgical procedure is called wide local excision. During this operation, the surgeon removes the melanoma along with a margin of healthy-looking skin around it. This margin acts as a safety zone to make sure that no cancer cells are left behind. The size of this margin depends on how thick the melanoma is. For very thin melanomas, a smaller margin may be enough, while thicker ones require a wider margin.^[11][12]

If the melanoma is in a visible area, such as the face, a plastic surgeon may perform the operation to minimize scarring and achieve the best cosmetic result. Sometimes, if a large area of skin needs to be removed, the surgeon may take skin from another part of the body and use it to cover the wound. This is called a skin graft.^[12]

For melanomas that are caught very early, when they are still sitting on the surface of the skin (stage 0 or melanoma in situ), surgery alone is usually enough. The five-year survival rate for people with stage 0 melanoma is about 97%, which means that most people are cured with surgery.^[3][15]

In some cases, doctors may recommend checking the sentinel lymph node. This is the first lymph node to which cancer cells are most likely to spread. During a procedure called a sentinel lymph node biopsy, the surgeon removes this node and examines it under a microscope to see if it contains cancer cells. If cancer is found in the sentinel node, the person may need additional surgery to remove more lymph nodes from that area, a procedure known as complete lymph node dissection. However, not everyone needs this, and doctors discuss the benefits and risks with each person.^[6][15]

Another surgical technique used for melanoma is called Mohs micrographic surgery. This is a precise method where the surgeon removes the melanoma in thin layers, examining each layer under a microscope right away. The process continues until no cancer cells are seen. This technique is sometimes used for melanomas on the face or other areas where preserving as much healthy skin as possible is important.^[6]

Additional Treatments After Surgery: Adjuvant Therapy

For some people with melanoma, surgery alone may not be enough to prevent the cancer from coming back. This is especially true for those with thicker melanomas, melanomas that have ulceration, or melanomas that have spread to the lymph nodes. In these situations, doctors may recommend adjuvant therapy, which means treatment given after surgery to lower the risk of the cancer returning.^[10][15]

One type of adjuvant therapy involves medicines that help the immune system recognize and attack any remaining cancer cells. These are called immunotherapy drugs. Two commonly used immunotherapy drugs for melanoma are pembrolizumab and nivolumab. Both belong to a class of medicines known as PD-1 inhibitors. They work by blocking a protein called PD-1 on immune cells, which allows the immune system to fight cancer more effectively.^[12][15]

Pembrolizumab is typically given through a vein (intravenously) every three weeks or every six weeks for up to one year. Studies have shown that people who receive pembrolizumab after surgery have a lower chance of their melanoma coming back compared to those who do not receive this treatment. Nivolumab is given every two weeks or every four weeks, also for up to one year. It has a similar effect in reducing the risk of recurrence.^[15]

Another type of adjuvant therapy is targeted therapy. This is used for people whose melanoma cells have a specific genetic change called a BRAF V600 mutation. About half of all melanomas have this mutation. Targeted therapy uses drugs that specifically attack cells with this mutation. Two drugs commonly used together are dabrafenib and trametinib. Dabrafenib is taken as a pill twice a day, and trametinib is taken once a day. This combination has been shown to help prevent melanoma from coming back after surgery in people with the BRAF mutation.^[15]

A third option for adjuvant therapy is a drug called ipilimumab. This is another type of immunotherapy that works by blocking a protein called CTLA-4. Ipilimumab is given intravenously every three weeks for four doses, followed by a dose every 12 weeks for up to three years. However, ipilimumab tends to have more side effects than pembrolizumab or nivolumab, so it is used less often today.^[15]

Side effects of immunotherapy can include fatigue, skin rashes, diarrhea, and inflammation of various organs such as the lungs, liver, or thyroid. Most side effects are manageable, but some can be serious and require stopping the treatment. Targeted therapy can cause fever, chills, fatigue, and skin problems. Doctors monitor people closely during treatment and adjust the plan if needed.^[12]

Treatment for Advanced Melanoma That Has Spread

When melanoma has spread to distant parts of the body, it is called metastatic melanoma or stage IV melanoma. Until recently, treatment options for metastatic melanoma were limited and often not very effective. However, in the past decade, new treatments have dramatically improved the outlook for people with advanced melanoma.^[3][13]

The two main types of treatment for metastatic melanoma are immunotherapy and targeted therapy, similar to those used after surgery, but often at different doses or in different combinations. Immunotherapy helps the immune system fight the cancer, while targeted therapy attacks specific genetic changes in the cancer cells.

For immunotherapy, doctors may use PD-1 inhibitors like pembrolizumab or nivolumab, either alone or in combination with other drugs. Another option is to combine nivolumab with ipilimumab. This combination has been shown to help more people than using either drug alone, but it also has more side effects. The choice depends on the person’s overall health and the characteristics of the melanoma.^[12][15]

For targeted therapy, the combination of dabrafenib and trametinib is used for people whose melanoma has the BRAF V600 mutation. These drugs can shrink tumors quickly and help people feel better. However, the cancer can sometimes develop resistance to these drugs over time, meaning they may stop working after several months or years. Researchers are studying ways to overcome this resistance.^[15]

In some cases, doctors may recommend chemotherapy, which uses powerful drugs to kill cancer cells. Chemotherapy is not as effective for melanoma as immunotherapy or targeted therapy, so it is usually used only when other treatments are not an option or have stopped working. Common chemotherapy drugs for melanoma include dacarbazine and temozolomide.^[12]

Another treatment option for advanced melanoma is radiation therapy. This uses high-energy rays to kill cancer cells. Radiation is not usually the main treatment for melanoma, but it can be helpful in certain situations, such as shrinking tumors that are causing pain or other symptoms, treating melanoma that has spread to the brain, or reducing the risk of the cancer coming back after surgery in areas where lymph nodes were removed.^[12]

For people with melanoma that cannot be removed by surgery but is limited to one area, such as an arm or leg, a technique called hyperthermic perfusion or infusion may be used. In this procedure, a heated chemotherapy drug, usually melphalan, is delivered directly to the affected limb through the blood vessels. This allows a high dose of the drug to reach the cancer while minimizing exposure to the rest of the body.^[15]

Promising New Therapies Being Tested in Clinical Trials

Clinical trials are research studies that test new treatments to see if they are safe and effective. Many people with melanoma consider joining a clinical trial, especially if standard treatments are not working well or if they want access to the latest therapies before they become widely available.^[10]

One exciting area of research is oncolytic virus therapy. This involves using genetically modified viruses that can infect and kill cancer cells while leaving healthy cells alone. One such therapy is talimogene laherparepvec, also known as T-VEC. This is a modified herpes virus that is injected directly into melanoma tumors. T-VEC not only kills the cancer cells it infects but also stimulates the immune system to attack other melanoma cells in the body. It is approved for treating melanoma that cannot be removed by surgery and is located in the skin or lymph nodes.^[15]

Another promising approach is cellular therapy, which involves collecting a person’s own immune cells, modifying them in a laboratory to better recognize and kill cancer cells, and then infusing them back into the person. One type of cellular therapy being studied is called tumor-infiltrating lymphocyte (TIL) therapy. TILs are immune cells that are naturally found inside tumors. In the lab, scientists grow large numbers of these cells and activate them to become more effective at killing cancer. Early studies have shown that TIL therapy can help some people with advanced melanoma whose cancer did not respond to other treatments.^[6]

Researchers are also testing new combinations of immunotherapy drugs. For example, some clinical trials are looking at combining PD-1 inhibitors with drugs that target other immune checkpoints or with targeted therapies. The idea is that using multiple treatments together may be more effective than using them one at a time. However, combining treatments can also increase side effects, so careful monitoring is needed.^[13]

Another area of investigation is neoadjuvant therapy, which means giving treatment before surgery. This is the opposite of adjuvant therapy, which is given after surgery. The goal of neoadjuvant therapy is to shrink the melanoma before it is removed, making surgery easier and more successful. Some studies have shown that giving immunotherapy before surgery can help more people have a complete response, meaning no cancer is found in the tissue removed during surgery.^[6]

For people with melanoma that has spread to the eye (uveal melanoma) or to the mucous membranes (the moist linings of the body, such as the mouth or nasal passages), clinical trials are exploring therapies tailored to these specific types of melanoma. Uveal and mucosal melanomas behave differently from skin melanoma and often do not respond as well to standard treatments, so new approaches are urgently needed.^[3][6]

Clinical trials go through different phases. Phase I trials test whether a new treatment is safe and help determine the right dose. Phase II trials look at whether the treatment works against the cancer. Phase III trials compare the new treatment to the current standard treatment to see if it is better. People in clinical trials are monitored very closely, and they can leave the trial at any time if they choose.^[3]

Clinical trials for melanoma are being conducted in many countries, including the United States, Europe, and other regions. Eligibility for a trial depends on factors such as the stage of melanoma, previous treatments received, overall health, and specific characteristics of the cancer. People interested in joining a clinical trial should talk to their doctor about whether there is a trial that might be a good fit for them.^[10]

Managing Side Effects and Quality of Life During Treatment

Treatment for melanoma can cause side effects that affect daily life. The type and severity of side effects depend on the treatment being used, the dose, and how each person’s body responds. It is important to talk openly with the medical team about any side effects, as many can be managed or reduced.^[16][18]

Surgery can cause pain, swelling, and scarring. If lymph nodes are removed, some people develop lymphedema, which is swelling in the arm or leg because fluid cannot drain properly. Wearing compression garments, doing special exercises, and seeing a physical therapist can help manage lymphedema.^[11]

Immunotherapy side effects happen because the treatment activates the immune system, which can sometimes attack healthy tissues. Common side effects include fatigue, skin rashes, diarrhea, and inflammation of the lungs, liver, thyroid, or other organs. These side effects can range from mild to severe. Doctors may prescribe medicines like steroids to reduce inflammation. In some cases, treatment may need to be stopped temporarily or permanently.^[12]

Targeted therapy can cause fever, chills, fatigue, nausea, skin problems, and sensitivity to sunlight. Some people also experience muscle or joint pain. Most side effects improve after stopping the medication or reducing the dose.^[12]

Chemotherapy can cause nausea, vomiting, hair loss, fatigue, and increased risk of infections because it affects the bone marrow where blood cells are made. Medicines are available to help with nausea, and doctors monitor blood counts closely to watch for signs of infection.^[12]

Radiation therapy can cause skin redness, peeling, and fatigue in the treated area. These side effects usually get better within a few weeks after treatment ends. Keeping the skin clean and moisturized can help.^[12]

Beyond physical side effects, melanoma and its treatment can take an emotional toll. Feelings of anxiety, fear, sadness, or anger are common. Some people find it helpful to talk to a counselor, psychologist, or psychiatrist who specializes in working with people who have cancer. Support groups, where people with melanoma can share experiences and advice, can also be valuable.^[17][18]

Practical support is also important. People undergoing treatment may need help with daily activities, transportation to appointments, or managing finances. Social workers and patient navigators can connect people with resources such as financial assistance programs, transportation services, and home care.^[17]

Life After Melanoma Treatment

After completing treatment, people with melanoma need regular follow-up care. The goal is to watch for signs that the cancer has come back or that a new melanoma has developed. People who have had one melanoma are at higher risk for developing another one in the future.^[22]

Follow-up care usually includes physical exams, skin checks, and sometimes imaging tests like CT scans or PET scans. The frequency of these visits depends on the stage of melanoma and how long ago treatment was completed. In the first few years after treatment, visits may be every few months. Over time, they may become less frequent.^[11][22]

Protecting the skin from further sun damage is crucial. People who have had melanoma should avoid spending long periods in the sun, especially between 10 a.m. and 4 p.m. when the sun’s rays are strongest. Wearing protective clothing, including long sleeves, pants, a wide-brimmed hat, and sunglasses, is important. Sunscreen with a high sun protection factor (SPF of 30 or higher) should be applied to all exposed skin and reapplied every two hours, especially after swimming or sweating. Tanning beds should be avoided entirely, as they significantly increase the risk of melanoma.^[22][23]

Regular self-exams are also important. People should check their entire body, including hard-to-see areas like the back, scalp, and soles of the feet, at least once a month. Any new or changing spots should be reported to the doctor right away. Taking photos of moles or using smartphone apps to track changes can be helpful.^[22]

Vitamin D is important for bone health, and sunlight is the main source of vitamin D for most people. However, covering up and using sunscreen can reduce vitamin D levels. Doctors may recommend a blood test to check vitamin D levels and may suggest taking a vitamin D supplement if levels are low. Foods like oily fish, eggs, and fortified cereals can also provide vitamin D.^[22]

Staying active and eating a healthy diet can support overall well-being during and after treatment. Exercise can help reduce fatigue, improve mood, and strengthen the body. People should talk to their doctor about what types and amounts of exercise are safe, especially after surgery. It is important not to overdo it and to listen to the body’s signals.^[20]

For many people, life after melanoma involves finding a new normal. Some people feel grateful and energized, while others struggle with fear of recurrence or ongoing side effects. Both reactions are valid. Finding ways to cope, whether through hobbies, spending time with loved ones, or seeking professional support, can help people adjust.^[18][19]
