Is Skin Cancer Itchy?

Yes, some skin cancers can itch, but itching by itself is much more commonly caused by benign conditions such as dry skin, eczema, irritation, or insect bites. Basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma can sometimes cause itching or other sensations, but many skin cancers cause no symptoms at all.

Rather than relying on itching alone, pay attention to a spot that is new, changing, persistently irritated, bleeding, crusting, painful, or not healing. A lesion with these features should be evaluated by a dermatologist, particularly if it continues to change over time.

Why Does Skin Cancer Itch?

The exact reason a skin cancer may itch is not always clear. Inflammation within and around a tumor can stimulate nearby sensory nerves, and some lesions may directly irritate or involve nerve endings. However, itching is a nonspecific symptom and does not by itself indicate that a lesion is cancerous.

Does Skin Cancer Itch and Burn?

Some skin cancers can cause itching, burning, stinging, tenderness, or pain, although many are completely asymptomatic. These sensations can also occur with common benign inflammatory skin conditions. Persistent symptoms are more concerning when they occur in a lesion that is also growing, changing, bleeding, crusting, or failing to heal.

Which Types of Skin Cancer Are Most Likely To Itch?

Itching can occur with several types of skin cancer, but it is reported more often with nonmelanoma skin cancers, particularly squamous cell carcinoma, than with melanoma. Symptoms alone cannot reliably distinguish one type of skin cancer from another, so the appearance and evolution of the lesion remain important.

Does Basal Cell Carcinoma Itch?

Basal cell carcinoma (BCC) may itch, bleed, crust, or become irritated, but it may also cause no symptoms. BCC can appear in several ways, including as a pearly or shiny bump, a persistent red or scaly patch, or a sore that repeatedly heals and reopens. A persistent or changing lesion, particularly one that bleeds or does not heal, should be evaluated by a dermatologist.

Does Squamous Cell Skin Cancer Itch?

Squamous cell carcinoma (SCC) can cause itching, tenderness, pain, burning, or stinging. It may appear as a rough or scaly patch, a firm or raised bump, a rapidly growing lesion, or a sore that crusts, bleeds, or does not heal. Because SCC can sometimes resemble benign irritated or scaly growths, persistent or changing lesions warrant examination.

Does Melanoma Itch?

Melanoma can itch, bleed, or become tender, but many melanomas have no physical symptoms. More important warning signs include a new or changing pigmented lesion, asymmetry, irregular borders, multiple or changing colors, or a spot that looks different from the others on your skin. Any evolving or otherwise suspicious lesion should be evaluated promptly.

Is Itching a Cancer Symptom?

Itching can be a symptom of skin cancer, but most itchy spots are not cancer. A bug bite or inflammatory rash usually improves with time, whereas a skin cancer may persist or continue to change. Because appearance is more informative than itching alone, watch for growth, color or shape changes, recurrent bleeding or crusting, or a sore that does not heal.

Other Symptoms To Watch For

When evaluating a concerning spot, consider the entire lesion rather than any single symptom. For pigmented lesions, the ABCDE rule is a useful guide for recognizing features that can be associated with melanoma:

• Asymmetry: One half of the lesion does not match the other.

• Border: The edges are irregular, scalloped, poorly defined, or blurred.

• Color: The color is uneven or includes multiple shades, such as brown, black, red, white, or blue.

• Diameter: Many melanomas are larger than 6 mm when diagnosed, but melanomas can be smaller.

• Evolving: The lesion is changing in size, shape, color, elevation, or symptoms such as itching or bleeding.

• Other warning signs include a spot that looks noticeably different from your other moles (sometimes called the “ugly duckling” sign), a sore that does not heal, recurrent bleeding or crusting, or a lesion that continues to grow or change.

When To See a Dermatologist

Most itching is caused by conditions other than skin cancer. However, consider seeing a dermatologist for a new or changing mole or growth, a lesion that repeatedly bleeds or crusts, a sore that does not heal, or persistent symptoms localized to a particular changing lesion. People with a personal history of skin cancer or other significant risk factors may need more frequent professional skin examinations based on their dermatologist’s recommendations.

Preventing Skin Cancer

Reducing ultraviolet (UV) exposure can lower the risk of developing skin cancer. Helpful sun-protection habits include:

• Use sun protection: Apply a broad-spectrum, water-resistant sunscreen with SPF 30 or higher to exposed skin and reapply as directed, especially after swimming or sweating. Combine sunscreen with shade, protective clothing, a wide-brimmed hat, and sunglasses.

• Avoid tanning beds: Indoor tanning exposes the skin to harmful UV radiation and increases the risk of skin cancer.

• Check your skin: Become familiar with your skin so you can recognize new, changing, or unusual spots. Pay attention to areas that are easy to overlook, including the scalp, back, soles of the feet, and around the nails.

• Discuss skin screening with your dermatologist: The appropriate frequency of professional skin examinations depends on individual risk factors, including personal history, family history, skin type, sun exposure, and other clinical factors.

Skin Cancer Diagnosis

A dermatologist evaluates a suspicious lesion based on its appearance, history, and examination, often with the aid of dermoscopy. If skin cancer is suspected, a skin biopsy is generally performed to establish the diagnosis. A pathologist then examines the tissue under a microscope to determine whether cancer is present and, when applicable, the type of skin cancer.

Skin Cancer Treatment Options

Treatment depends on the type, size, location, depth, and other risk features of the skin cancer, as well as the patient’s overall health. Options may include standard surgical excision, Mohs micrographic surgery, electrodesiccation and curettage, topical medications, radiation therapy, or systemic treatments in selected cases. Mohs surgery is commonly used for certain high-risk or anatomically sensitive basal and squamous cell carcinomas because it allows microscopic examination of the surgical margins while preserving as much healthy tissue as possible.

Schedule a Skin Check With Pinnacle Dermatology

Some skin cancers itch, while many do not. For that reason, itching should not be used alone to determine whether a spot is concerning. If you notice a new, changing, bleeding, persistently symptomatic, or nonhealing lesion, a dermatologist can examine the area and determine whether further evaluation, including a biopsy, is appropriate.

FAQs

What Type of Skin Cancer Is Most Likely to Itch?

Itching is reported more commonly with squamous cell carcinoma than with melanoma and can also occur with basal cell carcinoma. However, itching is nonspecific and cannot determine whether a lesion is cancerous or identify the type of skin cancer.

Why Does Skin Cancer Itch?

Inflammation around a skin cancer and stimulation or irritation of nearby sensory nerves may contribute to itching. The exact mechanism can vary, and many skin cancers do not itch.

Does Skin Cancer Hurt, or Is It Just Itchy?

Skin cancer can be itchy, painful, tender, or completely asymptomatic. Persistent pain, tenderness, or itching is more concerning when it occurs in a lesion that is also new, changing, bleeding, crusting, or not healing.

Can You Have Skin Cancer Without Visible Signs?

Skin cancers generally produce a skin lesion, but early changes can be subtle or occur in areas that are difficult to see, such as the scalp, back, soles of the feet, or around and beneath the nails. Regular awareness of your skin can help you notice new or changing lesions.

Can a Dermatologist Tell Right Away If a Spot Is Cancerous?

A dermatologist may strongly suspect skin cancer based on the clinical examination and dermoscopic features, but a biopsy is typically required to confirm the diagnosis.
