Does Melanoma Itch?

If you develop an itchy spot on your skin (pruritus), it may be more than irritating. For some, the sudden symptoms could indicate something more serious, including melanoma skin cancer. This blog will cover common causes of itchy skin and address the question, “Does melanoma itch?” We will also discuss other melanoma symptoms to watch for and when to schedule an appointment with your dermatologist for further assessment. 

Which Skin Cancers Itch? 

Melanoma is considered the most deadly skin cancer due to its ability to spread to other areas of the body. Early detection is critical to effective treatment and the best prognosis. Melanoma moles can itch, even before they become visibly evident.

Itching is most common in these types of melanomas:

• Superficial Spreading Melanoma: This type accounts for the majority of melanomas, starting as a new black or brown spot, or an existing mole that changes appearance. 
• Nodular Melanoma: This cancer is most frequent in individuals over 65 and often appears as bumpy growths on the skin that may bleed and crust over. 
• Lentigo Melanoma: These flat brown spots often appear on the face, head, ears, neck, arms, or legs and can quickly penetrate deeper tissue.
• Amelanotic Melanoma: This cancer is one of the most serious melanomas, often appearing as a red or skin-colored bump.

The majority of melanoma moles do not itch; in fact, some appear without itching, pain, or other accompanying symptoms. Melanoma isn’t the only skin cancer that can cause itchy skin, either. Both basal cell and squamous cell cancers are more often associated with itching than melanoma. Basal cell carcinoma, the most common skin cancer, rarely spreads, but prompt treatment prevents deep tissue damage. Squamous cell carcinoma is also highly treatable, but it can spread over time.

Other Causes of Itching 

Localized Pruritus

Localized pruritus can be linked to numerous skin conditions beyond cancer, such as: 

• Eczema 
• Actinic keratosis 
• Psoriasis 
• Insect bites
• Contact dermatitis 
• Fungal infections 
• Heat rash 

Even dry skin can lead to persistent itching, particularly in the late spring and early summer months in Scottsdale when the dry season is at its peak. 

Beyond the Itch: Early Stage Melanoma Symptoms

While itching can be linked to skin cancer, it is not the most common symptom. You can distinguish between benign itching and potential melanoma by watching for changes to moles and following the ABCDEs: 

• Asymmetry: If you divide your mole in half, one side should be a mirror image of the other. If the mole is asymmetrical, schedule an appointment with your doctor. 
• Borders: Moles with jagged or irregular borders are more likely to be cancerous than those with smooth, well-defined borders. 
• Color: Moles with uneven color are suspicious, which may include shades of black, brown, blue, red, pink, or white.
• Diameter: Larger moles, particularly those larger than a pencil eraser, are a cause for concern. 
• Evolving: Moles that suddenly appear or change color, size, elevation, or shape should be checked by your dermatologist.
