Melanoma: Understand Symptoms, Causes, Risk Factors, Prevention and More

Skin cancer is one of the most common cancers in the United States. As per the NIH report, in 2026 alone, an estimated 112,000 Americans may diagnosed with melanoma, and over 8,500 are at high risk of dying from it. If you have identified any of the skin cancer symptoms in you or your loved ones, don’t panic; there is a solution to deal with it. This blog page covers everything you need to know, from identifying early warning signs to learning how melanoma is diagnosed and treated.

The good news is that when caught early, melanoma is highly treatable. Understanding melanoma symptoms, causes, and risk factors puts you in the best position to protect yourself and your family.

What is Melanoma?

Melanoma is a type of skin cancer (the most dangerous form) that begins in melanocytes, the cells that produce melanin, the pigment that gives your skin its color. Unlike other forms of skin cancer, melanoma can spread rapidly to other body organs if not caught early. Timely detection is important to prevent this skin concern from spreading further. Melanoma most commonly develops on the skin, but it can also form in the eyes and, rarely, in the nose, throat, or other internal organs.

Types of Melanoma

There are several types of melanoma; identifying its type is crucial to start the right treatment:

1. Superficial spreading melanoma – This is the most common type, accounting for about 70% of all cases. It grows outward along the skin’s surface before penetrating deeper layers. It often appears as a flat or slightly raised discolored patch.
2. Nodular melanoma – This type is more aggressive and grows downward into the skin quickly. It usually appears as a raised bump in black, blue, or skin-coloured.
3. Lentigo maligna melanoma – It usually develops slowly, most often in older adults and in chronically sun-damaged areas such as the face, ears, and arms. It starts as a flat, tan, or brown patch that can grow over many years.
4. Acral lentiginous melanoma – A rare type of melanoma among white Americans, but it is the most common type in people with darker skin tones. It appears on the palms, soles of the feet, or under fingernails and toenails.
5. Amelanotic melanoma – This melanoma type is uncommon and often missed, as it lacks pigment. It may appear pink, red, or skin-colored, making it harder to recognize.

Melanoma Symptoms and the Warning Signs

The most important skill in early detection is knowing your own skin well. Melanoma symptoms often start as a change in an existing mole or the appearance of a new, unusual-looking growth. Dermatologists recommend the ABCDE rule for identifying suspicious spots:

• A — Asymmetry: One half of the mole doesn’t match the other.
• B — Border: Edges are irregular, ragged, notched, or blurred.
• C — Color: The color is not uniform; you may see shades of brown, black, pink, red, white, or blue.
• D — Diameter: The spot is larger than 6mm (about the size of a pencil eraser), though melanomas can be smaller.
• E — Evolving: The mole is changing in size, shape, color, or any other characteristic, or it begins to itch, bleed, or crust.

Other melanoma symptoms to watch for include a sore that doesn’t heal, a new swelling or lump beyond the border of a mole, and spreading color from the border of a mole into the surrounding skin. If you notice any of these warning signs, see a dermatologist right away. Early-stage melanoma is almost always curable, while advanced melanoma is far more difficult to treat.

What causes melanoma?

Melanoma causes are not fully understood, but it is believed that ultraviolet (UV) radiations are the primary cause. UV rays from sunlight and artificial sources, such as tanning beds (sunbeds), damage DNA in skin cells. Over time, this damage can trigger abnormal cell growth that can develop into melanoma. UV exposure is responsible for more than 80% of all melanoma cases in the US. However, melanoma can also develop in areas of the body rarely or never exposed to the sun, probably due to genetic and environmental factors. Genetic mutations are a significant cause. About 40–50% of melanomas harbour a BRAF mutation, which causes cells to grow uncontrollably. This mutation is particularly important because it influences treatment options.

Melanoma risk factors

Knowing melanoma risk factors helps assess personal risk and take appropriate precautions. The main risk factors include:

1. UV exposure – A history of sunburns, especially blistering sunburns in childhood, significantly raises your risk. Regular, prolonged sun exposure and indoor tanning also increase risk.
2. Fair skin, hair, and eyes – People with lighter skin have less melanin, offering less natural protection from UV radiation. Blond or red hair and blue or green eyes are also associated with a higher risk.
3. Many moles – Having more than 50 ordinary moles, or having atypical moles (dysplastic nevi) that are larger, irregularly shaped, or unevenly colored, raises your melanoma risk considerably.
4. Personal or family history – If you have had melanoma before, you are at higher risk for a recurrence. A family history of melanoma also elevates risk, particularly if a first-degree relative has been diagnosed.
5. Weakened immune system – People who take immunosuppressant medications, those living with HIV/AIDS, and organ transplant recipients are at increased risk because their immune systems are less able to detect and destroy abnormal cells.
6. Older age – While melanoma can affect people of any age, it’s one of the most common cancers in people under 30, and the risk increases with age. The average age of diagnosis is 65.
7. Gender – Before age 50, women are more likely than men to develop melanoma. After 50, men have a higher incidence.

When to see a doctor?

Don’t wait for a mole to “get worse”, visit for evaluation if you notice:

• A new mole or skin growth that appears after age 30
• Any mole that changes in size, shape, or color
• A mole that bleeds, itches, or becomes painful
• A sore that does not heal within a few weeks
• A dark streak under a fingernail or toenail

Melanoma caught at Stage I has a 5-year survival rate of over 98%. By Stage IV, that drops significantly. Early action saves lives.

Melanoma diagnosis

Melanoma diagnosis typically begins with a full-body skin exam by a dermatologist. If a suspicious lesion is found, the doctor will perform a skin biopsy, removing part or all of the lesion and sending it to a lab for analysis. A biopsy is the only definitive way to diagnose melanoma. If melanoma is confirmed, additional tests help determine how far it has spread (the stage). These may include a sentinel lymph node biopsy, CT scans, PET scans, MRI, or blood tests.

Melanoma is staged from 0 through Stage IV. The stage of cancer strongly influences treatment decisions and prognosis.

Melanoma treatment options

Melanoma treatment depends on the stage of the cancer, it’s location, and the patient’s overall health. The main treatment options include:

1. Surgery is the primary treatment for early-stage melanoma. The surgeon removes the tumor along with a margin of healthy skin. In many early cases, surgery alone is curative.
2. Immunotherapy has transformed melanoma treatment for advanced cases. It works by boosting the body’s own immune system to recognize and attack cancer cells. Checkpoint inhibitors such as pembrolizumab (Keytruda) and nivolumab (Opdivo) have dramatically improved survival rates for Stage III and IV melanoma.
3. Targeted therapy is used for melanomas carrying the BRAF gene mutation. Targeted drugs such as vemurafenib and dabrafenib block signals that drive cancer cell growth. These are often used in combination for greater effectiveness.
4. Radiation therapy may be used after surgery to kill remaining cancer cells or to treat melanoma that has spread to the brain or bones.
5. Topical treatments for very early-stage or superficial skin lesions, including precancerous growths and early non-melanoma skin cancers, can be effective. Imiquad (Imiquimod 5% cream) is an immune response modifier that stimulates the body’s local immune response to destroy abnormal skin cells. It is FDA-approved for superficial basal cell carcinoma and certain precancerous conditions, and is sometimes used off-label in select melanoma cases under physician guidance. Efudix (5-Fluorouracil) is a topical chemotherapy cream used for treating actinic keratoses and superficial skin cancers. It targets rapidly dividing abnormal cells and is particularly effective for precancerous lesions that, if left untreated, could progress to invasive cancer. Always use these treatments only under the guidance of a licensed healthcare provider.
6. Chemotherapy is less commonly used for melanoma today because targeted therapy and immunotherapy have largely replaced it, but it may be an option when other treatments are not available or have failed.

Melanoma prevention

Most melanoma cases are preventable, and the most powerful step is to reduce your UV exposure. Let’s find out how:

1. Wear sunscreen daily – Apply a broad-spectrum sunscreen with SPF 30 or higher every day, even on cloudy days and in winter. Reapply every two hours when outdoors, and more often if swimming or sweating. Look for products offering both UVA and UVB protection.
2. Avoid peak sun hours – UV rays are strongest between 10 a.m. and 4 p.m. Seek shade whenever possible during these hours.
3. Cover up your skin — Wear protective clothing (long sleeves, wide-brimmed hats, and UV-blocking sunglasses) when spending time outdoors.
4. Skip the tanning bed – Indoor tanning significantly raises your risk of melanoma. There is no such thing as a “safe tan” from a tanning bed.
5. Perform monthly skin self-exams – Get familiar with every mole and mark on your body. Check yourself from head to toe in a well-lit room using mirrors. Look for any changes using the ABCDE guide. Report anything new or changing to a dermatologist promptly.
6. Get annual professional skin exams – See a board-certified dermatologist once a year for a full-body skin check and more often if you have risk factors.
7. Protect your skin’s health with proven skincare – Daily use of skin-supporting products helps maintain skin integrity. Retin A Cream (Tretinoin) promotes skin cell turnover, helping keep the top layers of skin healthy, and is used by dermatologists for a range of skin conditions, including UV-damaged skin. Melalite Forte Cream (Hydroquinone 4%) is used for managing hyperpigmentation and uneven skin tone associated with sun damage. Triluma Cream is a combination of hydroquinone, tretinoin, and fluocinolone, a clinically proven treatment for skin discolouration caused by sun damage and melasma.

The skin care after melanoma treatment

Recovering from melanoma treatment requires attentive skin care. The treated area may be sensitive, more prone to sunburn, and vulnerable to additional UV damage. Patients are advised to be even more vigilant about sun protection. Maintaining a regular skincare routine with gentle cleansers, moisturizers, and daily broad-spectrum sunscreen is essential. Dermatologist-recommended topical products can help restore and protect the skin barrier during and after treatment.
