Can Skin Cancer Look Like A Wart?

First published: April 7, 2023

Yes, skin cancer can look like a wart, especially certain types like squamous cell carcinoma or even some forms of basal cell carcinoma. These skin cancers can look like rough, raised, or scaly skin growths, making it difficult to tell the difference at first glance.

A persistent bump that bleeds, crusts, or fails to heal is a key warning sign that a wart-like lesion may be cancerous. Because skin cancer can develop in areas frequently exposed to the sun, early evaluation by a dermatologist is critical for early detection and accurate diagnosis.

In this article, we’ll discuss how to identify a wart vs skin cancer and how to take control of your health and wellness with potential therapies such as skin cancer alternative treatment.

What Are Warts? Understanding These Common Skin Growths

Warts are small, typically harmless skin growths caused by certain strains of the human papillomavirus (HPV). There are over 40 different types of HPV, and they can be transmitted through direct or indirect contact. 

While they can develop anywhere on the body, warts often appear on the hands, fingers, feet, or face. They’re considered contagious and may spread through direct skin contact or shared surfaces like gym equipment. It is important to differentiate between warts and skin cancer, as early diagnosis and treatment can greatly improve outcomes.

Types of Warts

• Common warts – Raised, rough bumps usually found on fingers and hands.
• Plantar warts – Hard, sometimes painful warts that grow on the soles of the feet.
• Flat warts – Smooth, small lesions that can appear anywhere on the body.
• Oropharyngeal warts – Found on the tongue, cheek, or oral surfaces, and should be checked to determine if they are oral cancer, canker sores, or warts.
• Genital warts – Linked to specific HPV strains and should always be examined by a healthcare provider.

While warts are benign and generally harmless, they can sometimes resemble more serious skin conditions. If a wart changes color, grows rapidly, bleeds, or becomes painful, it’s important to seek professional evaluation.

Wart Treatment and Prevention: What You Should Know

Many warts are harmless and may disappear on their own without treatment. This natural process can take anywhere from 1 to 5 years, depending on the size and location of the wart and your immune response. However, if warts are large, painful, or located in sensitive areas, treatment may be necessary for comfort and prevention of spreading.

Common Wart Treatment Options 

If you choose to remove a wart, several effective treatment methods are available:

• Salicylic acid – a topical treatment that helps peel away layers of the wart.
• Cryotherapy – freezing the wart with liquid nitrogen.
• Duct tape therapy – covering the wart to suffocate and encourage removal.
• Surgical removal – cutting out the wart.
• Electrocautery – burning off the wart with electric current.
• Laser treatment – using concentrated light beams to destroy the wart.
• Photodynamic therapy – using light-sensitive medication and a light source.
• Chemical treatments – applying stronger chemicals to dissolve wart tissue.
• Topical creams – prescription creams that help stimulate the immune system.
• Cantharidin application – a blistering agent applied by a healthcare provider.
• Antigen shots – injections to stimulate the immune system to fight off the wart.

The HPV and Cancer Connection

While most warts are harmless or benign, it’s important to note that certain strains of human papillomavirus (HPV) can cause warts in or around the genital area, potentially increasing the risk of developing cervical cancer and other cancers. For this reason, anyone who discovers genital warts should see a doctor or dermatologist for proper evaluation and care.

Tips to Prevent Spreading Warts 

Because warts can be contagious, following simple precautions can help prevent their spread:

• Avoid touching other people’s warts or your own.
• Do not share personal items like towels, razors, or nail clippers.
• Avoid scratching or picking at warts.
• Keep fingernails trimmed and avoid biting nails if warts are nearby.
• Wear sandals or flip-flops in communal showers, locker rooms, and pool areas.

When to See a Medical Professional

If you’re uncertain whether a bump, lesion, or skin growth is a wart or potentially skin cancer, it’s always best to consult a healthcare provider. It’s important to see a dermatologist if you notice:

• A skin growth that doesn’t heal
• A bump that bleeds, crusts, or changes in appearance
• A mole or lesion that looks unusual compared to your normal skin
• Any new growth in areas frequently exposed to the sun

A simple biopsy can determine whether a lesion is a wart, basal cell carcinoma, melanoma, or another type of skin cancer. Early evaluation can help catch skin cancer early and improve outcomes.

What Is Skin Cancer?

Skin cancer is the abnormal growth of skin cells, typically caused by prolonged exposure to ultraviolet (UV) radiation from sunlight or tanning beds. Unlike harmless warts or skin tags, skin cancer can spread to surrounding tissues or deeper layers of skin if left untreated.

Types of Skin Cancer

• Basal cell carcinoma – The most common, least dangerous, typically slow-growing, and found on sun-exposed areas.
• Squamous cell carcinoma – Can resemble a wart-like lesion and may bleed or crust.
• Melanoma – The most dangerous type, often developing from existing moles and known for rapid spread. It can invade nearby tissues and spread to distant organs, like the lungs, liver, or brain if not caught early.

Identifying skin cancer if present, is important here. This is why it’s essential to perform regular skin self-checks and schedule professional dermatology exams if you notice suspicious growths.

The ABCDE Rule for Spotting Melanoma

When it comes to skin cancer, one of the most important tools we like to share is the ABCDE rule. This simple guide helps you stay alert to common warning signs of malignant melanoma. Most melanomas begin in existing skin moles, so whether you’re examining a mole, wart, or any skin change, remember the ABCDE rule and perform monthly self-checks:

• A (Asymmetry) – If one half of the mole doesn’t match the other, take note.
• B (Border) –Watch for notched, blurred, or irregular edges.
• C (Color) –Look for uneven colors like shades of brown, black, pink, red, white, or blue.
• D (Diameter) – Be cautious if the spot is larger than a pencil eraser (about 1/4 inch across).
• E (Evolving) – Pay attention to changes in shape, size, or color over time.

Protecting your skin is key to lowering your risk of developing skin cancer. Wear sunscreen daily, avoid peak sunlight hours, skip tanning beds, and choose protective clothing like broad-brimmed hats.

Skin Cancer That Looks Like A Wart

Sometimes, skin cancer that looks like a wart can appear as a small bump, rough patch, or scaly lesion. These growths may look different from normal skin but still resemble common skin conditions like warts or skin tags.

It is important to be able to differentiate between the two conditions in order to seek appropriate medical treatment. While warts tend to be harmless, it’s crucial to note that skin cancer takes on many different forms. Abnormal looking skin moles, freckles, and warts can often be skin cancer in disguise, so it’s important to know how to tell if a wart is cancerous.

Wart vs Skin Cancer: How Do You Tell Them Apart?

It can be difficult to differentiate between warts and skin cancer, especially since some types of skin cancer can mimic wart-like bumps. Here are a few signs to help you understand the difference:

Warts

• Typically small, rough-textured growths
• Usually flesh-colored or slightly darker
• Appear suddenly and may cluster
• Caused by HPV and are contagious
• Often found on hands, feet, or knees
• Usually harmless, but can become painful

Skin Cancer

• Growths or lesions that bleed, crust, or don’t heal
• Change in color, shape, or size over time
• May look like a new mole or existing mole changing
• Can develop anywhere on the body, especially sun-exposed areas
• Requires prompt medical attention for diagnosis and treatment

If you have a bump that persists, especially if it crusts or bleeds, it’s time to see the doctor for a diagnosis so you can be treated. As we like to say – when in doubt, get it checked out. A doctor can perform a biopsy to let you know if it’s a wart, skin tag, or skin cancer. After diagnosis, there are several treatment options, ranging from laser cancer treatment to whole-body hypothermia.

This table highlights why skin cancers can look like warts, but also shows the subtle differences that matter for early detection.

Signs Your Wart Might Be Something More Serious

While most warts are harmless, certain warning signs might suggest a skin cancer or precancerous lesion:

• Rapid growth or change in size
• Irregular borders or unusual colors (pink, red, black, or white patches)
• Persistent bleeding or crusting
• Pain, itching, or tenderness
• Growths that don’t respond to typical wart treatments

If you notice any of these changes, schedule a skin check at your local dermatology clinic. A simple biopsy, a painless procedure to sample tissue cells can help diagnose any concerns.

Prevention and Treatment: Natural Options for Wart Removal

While traditional wart treatments include freezing (cryotherapy), salicylic acid, or minor surgical removal, some patients explore skin cancer natural treatments to help support skin health:

• Tea tree oil – Tea tree oil (or Melaleuca alternifolia) has antimicrobial and exfoliating properties. In a small study, it was found that topical wart treatments with tea tree oil reduce warts.
• Apple cider vinegar – A popular wart removal treatment with apple cider vinegar calls for soaking a cotton ball in the vinegar and applying it to the skin before bedtime. Protect the wart and keep the cotton ball in place by using a piece of tape or a bandage. Remember that apple cider vinegar is acidic and can cause irritation in some people.
• Echinacea – Also called the purple coneflower, it’s been shown that taking echinacea as an oral supplement or tea can help reduce the incidence of a stubborn wart.
• Ficus carica –  In study participants, a latex from this type of fig tree helped to reduce the occurrence of warts.
• Garlic ointments – Garlic ointments have been shown to reduce warts when applied topically.
• Dietary improvements – A nutrient-rich diet can help support skin health overall.
