Melanoma
For melanoma, surgery, immunotherapy, and targeted therapies are coordinated as a personalized plan across our accredited network.
What is melanoma (skin cancer)?
Melanoma is the most serious type of skin cancer, arising from the melanocytes that give skin its color. It tends to spread faster than other skin cancers.
When caught early, it can largely be treated with surgery. That is why noticing changes in moles early is vital.
What are the types of melanoma?
Main types:
Causes and risk factors
Main risk factors:
- Excessive sun (UV) exposure and sunburns
- Use of tanning beds
- Fair skin, freckles, blond/red hair
- Many moles or atypical moles
- Family history of melanoma
- A suppressed immune system
What are the symptoms of melanoma? (ABCDE rule)
The following changes in moles are warning signs:
- A – Asymmetry: the two halves of the mole differ
- B – Border: irregular, ragged edges
- C – Color: color variation or change
- D – Diameter: larger than 6 mm
- E – Evolving: change in size, color, or shape over time
- Moles that itch, bleed, or crust
What are the stages of melanoma?
Staging is based on tumor thickness (Breslow) and spread:
How is melanoma diagnosed?
Diagnosis is confirmed by biopsy:
- Dermoscopic skin examination
- Removal of the suspicious mole with pathology (excisional biopsy)
- Sentinel lymph node biopsy
- Genetic/molecular tests when needed (BRAF)
Imaging methods in melanoma
For assessing spread:
- Lymph node ultrasound
- PET-CT (spread screening)
- Brain MRI (when metastasis is suspected)
- Chest-abdomen CT
Melanoma treatment methods
Surgery in early stage, systemic therapies in advanced disease:
Every patient and every tumor is different
No single treatment is right for everyone; the best plan depends on your exact diagnosis, stage, and tumor characteristics. At National Cancer Alliance, we arrange a free second opinion from board-certified oncologists to review your case.
Prognosis and survival rates
Early diagnosis is the most important factor determining prognosis in melanoma. In early disease confined to the skin surface, 5-year survival is about 99%, falling with distant metastasis.
In recent years, advances in immunotherapy and targeted therapy have fundamentally improved survival in advanced melanoma. Thin melanomas are almost entirely treatable.
How to reduce melanoma risk
This cancer is largely preventable:
- Avoiding direct exposure in strong sun (10:00–16:00)
- Using high-factor sunscreen
- Protective clothing, hats, and sunglasses
- Avoiding tanning beds
- Checking moles regularly and showing changes to a dermatologist
Frequently asked questions
Is every mole dangerous?
No. The vast majority of moles are harmless. What matters are moles that meet the ABCDE criteria or that change.
Does melanoma only occur in sun-exposed areas?
No. It can occur on the soles, under nails, and in non-sun-exposed areas; a full-body check is important.
Is thin melanoma dangerous?
Thin, early-caught melanomas can usually be treated with surgery alone and have an excellent prognosis.
Should I get a second opinion?
Immunotherapy and targeted options in advanced melanoma evolve rapidly; an independent review ensures the most current plan.
