What Does Skin Cancer Look Like?

Skin cancer touches millions of lives every year, making it the most common cancer in the U.S. Often overlooked, your skin serves as your body’s largest and most visible line of defense, shielding you from the outside world. 

It works tirelessly, but it needs your attention too. Every freckle, mole or change tells a story, and knowing which ones to take seriously can protect your health in remarkable ways. By understanding the signs of skin cancer and acting early, you can take charge of your skin’s health. This blog will walk you through what to watch for and when it’s time to see a physician.

We speak to Kevin Jolliff, M.D., a board-certified general surgeon with INTEGRIS Health Medical Group General Surgery South, to learn more. 

“You should see a doctor for skin cancer concerns if you notice any new, unusual or changing spots on your skin,” Jolliff says. “This includes moles or lesions that grow, change color, have irregular borders, bleed, itch persistently or don’t heal. Early evaluation is key, as skin cancer is most treatable when caught early.”

Types of skin cancer and their appearance

At a glance: Skin cancer comes in several types, each with distinct appearances. Understanding this information is crucial for early detection and treatment. The best way to know how skin cancer looks and its appearance is by familiarizing yourself with visual examples and learning the key characteristics of different types.

Basal cell carcinoma (BCC) is the most common and least aggressive skin cancer.

• BCC appears as a pearly or waxy bump, often with visible blood vessels that may also have a central depression or ulceration.
• They are also flat, flesh-colored and have a brown scar-like lesion.
• Common locations include areas exposed to the sun, like the face, neck and arms.
• BCC is usually painless but may bleed, crust or ooze and it rarely itches.

Squamous cell carcinoma (SCC) is a more aggressive cancer that can occur on sun-damaged skin.

• SCC appears as a firm, red nodule or a flat lesion with a scaly, crusted surface.
• It may also resemble a wart or an open sore that doesn’t heal.
• Common locations include sun-exposed areas like the face, ears, hands and lips.
• SCC can be tender or painful and it may itch or bleed.

Melanoma is the deadliest form of skin cancer.

• Melanoma shows up as an irregularly shaped mole or spot with uneven borders.
• The colors vary, including shades of brown, black, red, white or blue.
• The size of melanoma is usually larger than a pencil eraser (6 mm) and may change over time.
• Lesions can appear anywhere, even in areas not exposed to the sun, like the soles of the feet or under nails.
• Symptoms include itching, bleeding or a tender feeling.
• Just five sunburns can double your risk of developing melanoma, according to the Skin Cancer Foundation.

Merkel cell carcinoma is a rare but aggressive cancer that appears on sun-exposed areas.

• Merkel cell carcinoma looks like a firm, shiny nodule that can be red, pink or purple.
• It grows rapidly and shows up on sun-exposed areas like the face, neck and arms.
• This type of carcinoma is usually painless but can grow aggressively.

Actinic keratosis (precancerous lesion) is caused by sun damage and can develop into SCC if untreated.

• Precancerous lesions look like rough, scaly patches that may be pink, red or brown.
• They show up in sun-exposed areas like the face, scalp and hands.
• Symptoms include itchiness and tenderness.

Does skin cancer hurt or itch?

Skin cancer is not always painful.

• However, some types, like SCC, can become tender or sore, especially if they grow or ulcerate.

Itching is not a universal symptom but can occur, particularly with melanoma or SCC. 

• Persistent itching in a mole or lesion should be evaluated.
• Melanoma or squamous cell carcinoma may irritate surrounding skin or nerve endings, leading to an itchy sensation.

When to see a doctor for skin cancer concerns

New or changing skin lesions can be a cause for concern.

• This includes a new mole, bump or spot that appears suddenly and looks unusual.
• An existing mole or spot that changes in size, shape, color or texture should be followed up on.

Follow the ABCDEs of melanoma, which is a way to identify skin cancer.

• Asymmetry means one half of the mole doesn’t match the other.
• Borders describe edges that are irregular, ragged or blurred.
• Color identifies uneven colors, including shades of brown, black, red, white or blue.
• Diameter includes spots larger than 6 mm (about the size of a pencil eraser).
• Evolving means any change in size, shape, color or symptoms (itching, bleeding).

Symptomatic changes should be monitored, especially if they’re unusual or painful.

• Any sore that doesn’t heal in a few weeks or heals and reopens repeatedly.
• Spots or moles that bleed, ooze or crust without injury.
• Lesions that become tender or painful to touch.
• Persistent itching in a mole or lesion, especially with other changes.
• Bumps or lesions growing quickly over weeks or months.
• Shiny, pearly bumps; flat, scaly patches or red, wart-like growths.

Additional risk factors include family history and behavioral risk factors. 

• A family or personal history of skin cancer warrants seeing a doctor to monitor any skin changes.
• If you have significant sun exposure, use tanning beds or have fair skin, you should see a doctor for regular skin checks, even if you don’t notice any specific changes.
