Causes & Risk Factors
Several factors can contribute to Melanoma.
Melanoma develops when DNA damage occurs in melanocytes, the pigment-producing cells in your skin.
Melanoma develops when DNA damage occurs in melanocytes, the pigment-producing cells in your skin. Most of this damage comes from ultraviolet radiation, whether from the sun or artificial sources like tanning beds. UV rays penetrate the skin and alter the genetic material in cells, causing them to multiply rapidly and form malignant tumors.
The relationship between sun exposure and melanoma isn't always straightforward.
The relationship between sun exposure and melanoma isn't always straightforward. Intense, intermittent exposure that leads to sunburns appears more dangerous than gradual, consistent tanning. This explains why melanoma sometimes develops on areas of the body that rarely see sunlight, and why people who work outdoors don't always have the highest risk.
Genetic factors also play a significant role in melanoma development.
Genetic factors also play a significant role in melanoma development. Some people inherit mutations that make their cells more susceptible to UV damage or less able to repair that damage effectively. Additionally, having many moles or atypical moles increases melanoma risk, as these represent areas where melanocytes are already somewhat abnormal and more likely to become cancerous.
Risk Factors
- History of severe sunburns, especially in childhood
- Fair skin that burns easily and tans poorly
- Family history of melanoma or other skin cancers
- Personal history of melanoma or other skin cancers
- Having many moles or unusual-looking moles
- Regular use of tanning beds or sun lamps
- Living at high altitudes or in sunny climates
- Weakened immune system from medications or illness
- Age over 50 years
- Male gender
- Having freckles or red or blonde hair
- Certain genetic conditions affecting skin pigmentation
Diagnosis
How healthcare professionals diagnose Melanoma:
- 1
Diagnosing melanoma typically begins with a thorough skin examination by a dermatologist or other qualified healthcare provider.
Diagnosing melanoma typically begins with a thorough skin examination by a dermatologist or other qualified healthcare provider. During this exam, the doctor inspects your entire body, looking for suspicious moles or growths using the ABCDE criteria: Asymmetry, Border irregularity, Color variation, Diameter larger than 6mm, and Evolution or changes over time. They may use a special magnifying tool called a dermatoscope to examine concerning areas more closely.

If a suspicious lesion is found, the next step is usually a biopsy.
If a suspicious lesion is found, the next step is usually a biopsy. The doctor removes all or part of the abnormal tissue for examination under a microscope by a pathologist. There are several types of biopsies, but an excisional biopsy that removes the entire lesion is preferred when melanoma is suspected. The pathologist examines the tissue to determine if cancer cells are present and, if so, how deep they extend into the skin.

Once melanoma is confirmed, additional tests may be needed to determine if the cancer has spread.
Once melanoma is confirmed, additional tests may be needed to determine if the cancer has spread. These staging procedures might include blood tests, imaging studies like CT or PET scans, and sometimes sentinel lymph node biopsy. The stage of melanoma, which describes how far it has spread, is crucial for determining the best treatment approach and predicting outcomes. Early-stage melanomas confined to the skin have excellent prognosis, while advanced melanomas that have spread require more aggressive treatment.
Complications
- The most serious complication of melanoma is metastasis, when cancer cells spread from the original skin tumor to other parts of the body.
- Melanoma has a particular tendency to spread to lymph nodes, lungs, liver, brain, and bones.
- Once melanoma metastasizes, it becomes much more challenging to treat, though modern immunotherapy and targeted treatments have dramatically improved outcomes even for advanced disease.
- Even after successful treatment, melanoma survivors face an increased risk of developing new melanomas.
- Studies show that people who have had one melanoma have a 5-10% chance of developing another primary melanoma during their lifetime.
- This makes lifelong surveillance with regular dermatology appointments and careful skin self-examinations absolutely essential.
- Some patients may also experience long-term effects from treatment, including surgical scarring, lymphedema if lymph nodes were removed, or side effects from immunotherapy or targeted drugs that can affect various organ systems.
Prevention
- Preventing melanoma centers on protecting your skin from harmful UV radiation throughout your life.
- This means seeking shade during peak sun hours (10 AM to 4 PM), wearing protective clothing including wide-brimmed hats and long-sleeved shirts, and applying broad-spectrum sunscreen with an SPF of 30 or higher every day, even on cloudy days.
- Sunscreen should be reapplied every two hours and after swimming or sweating.
- Avoid tanning beds and sun lamps entirely, as these artificial UV sources significantly increase melanoma risk.
- If you want a tan appearance, consider sunless tanning products instead.
- For children, prevention is especially critical since severe sunburns in childhood and adolescence substantially increase lifetime melanoma risk.
- Babies under six months should be kept out of direct sunlight, while older children need careful sun protection and should learn good sun safety habits early.
- Regular skin self-examinations and professional skin checks are essential for early detection, which is your best defense if melanoma does develop.
- Examine your skin monthly, looking for new growths or changes in existing moles using the ABCDE criteria.
- Take photos of concerning areas to track changes over time.
- See a dermatologist annually for a full-body skin exam, or more frequently if you have risk factors like fair skin, many moles, or a family history of melanoma.
Treatment for melanoma depends heavily on the stage and location of the cancer.
Treatment for melanoma depends heavily on the stage and location of the cancer. For early-stage melanomas that haven't spread beyond the skin, surgical removal is often the only treatment needed. The surgeon removes the tumor along with a margin of healthy tissue around it to ensure all cancer cells are eliminated. The size of this margin depends on the thickness and characteristics of the melanoma.
When melanoma has spread to nearby lymph nodes, treatment becomes more complex.
When melanoma has spread to nearby lymph nodes, treatment becomes more complex. Surgery to remove affected lymph nodes is typically performed, often followed by adjuvant therapy to reduce the risk of recurrence. This might include immunotherapy drugs like pembrolizumab or nivolumab, which help the immune system recognize and attack cancer cells, or targeted therapy drugs for melanomas with specific genetic mutations.
For advanced melanoma that has spread to distant parts of the body, treatment has been revolutionized in recent years.
For advanced melanoma that has spread to distant parts of the body, treatment has been revolutionized in recent years. Immunotherapy combinations, such as ipilimumab plus nivolumab, have shown remarkable success in helping some patients achieve long-term remission. Targeted therapies that block specific proteins driving cancer growth, like BRAF and MEK inhibitors, can be highly effective for melanomas with certain mutations. These treatments have transformed melanoma from a universally fatal diagnosis to a manageable condition for many patients.
Radiation therapy plays a supporting role in melanoma treatment, sometimes used after surgery to reduce recurrence risk or to treat melanoma that has spread to the brain or other organs.
Radiation therapy plays a supporting role in melanoma treatment, sometimes used after surgery to reduce recurrence risk or to treat melanoma that has spread to the brain or other organs. Clinical trials continue to explore new treatment combinations and approaches, including newer immunotherapy drugs, personalized vaccines, and innovative surgical techniques. The rapidly evolving treatment landscape means that even patients with advanced melanoma have reason for hope.
Living With Melanoma
Living with melanoma requires developing new habits around sun protection and medical follow-up that become second nature over time. Survivors typically need dermatology appointments every 3-6 months initially, gradually extending to annual visits if no new concerns arise. Between appointments, monthly self-skin exams become part of your routine, and many people find it helpful to use smartphone apps or photos to track changes in their skin.
