Understanding the Three Main Types of Skin Cancer

August 27, 2026

Skin cancer is the most common type of cancer, but when detected early, it is often highly treatable. Knowing the different types of skin cancer—and recognizing their warning signs—can help you seek treatment sooner and protect your long-term health.


The three main types of skin cancer are basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma. While all three develop from abnormal skin cell growth, they differ in where they begin, how they behave, and the treatment they require.


What Causes Skin Cancer?


Most skin cancers develop after years of exposure to ultraviolet (UV) radiation from the sun or tanning beds. UV rays damage the DNA in skin cells, and over time, this damage can cause cells to grow uncontrollably.


Several factors can increase your risk, including:

  • Frequent sun exposure
  • A history of blistering sunburns
  • Indoor tanning
  • Fair skin, light-colored eyes, or blond or red hair
  • A weakened immune system
  • Family or personal history of skin cancer
  • Increasing age


While anyone can develop skin cancer, understanding your risk can help you take preventive steps.


Basal Cell Carcinoma (BCC)

Basal cell carcinoma is the most common type of skin cancer. It begins in the basal cells, which are found in the lowest layer of the epidermis. BCC usually grows slowly and rarely spreads to other parts of the body. However, if left untreated, it can continue to enlarge and damage nearby skin, muscles, cartilage, and bone.


Common Signs of Basal Cell Carcinoma

You may notice:

  • A shiny or pearly bump
  • A flesh-colored or pink growth
  • A sore that won't heal
  • A flat, scar-like patch
  • A lesion that repeatedly bleeds or crusts


Basal cell carcinoma most often develops on areas that receive frequent sun exposure, such as the face, ears, scalp, neck, and shoulders.


Squamous Cell Carcinoma (SCC)

Squamous cell carcinoma develops in the squamous cells that make up the outer layer of the skin. Although SCC is generally more aggressive than basal cell carcinoma, it is highly treatable when diagnosed early. If left untreated, it has a greater chance of spreading to nearby lymph nodes or other parts of the body.


Common Signs of Squamous Cell Carcinoma

Look for:

  • A rough, scaly red patch
  • A thickened or wart-like growth
  • An open sore
  • A crusted bump that continues to enlarge
  • A lesion that becomes tender or painful


Like BCC, SCC commonly appears on sun-exposed areas, including the face, scalp, ears, hands, and arms.


Melanoma

Melanoma is the most serious form of skin cancer because it can spread quickly if not detected early. Melanoma develops in melanocytes, the cells that produce melanin, the pigment responsible for skin color. Although it accounts for a smaller percentage of skin cancer cases, it causes the majority of skin cancer-related deaths. The good news is that melanoma is highly treatable when found in its earliest stages.


Warning Signs of Melanoma

Melanoma often appears as a new mole or a change in an existing mole. Dermatologists recommend using the ABCDE Rule to identify suspicious lesions:

  • A – Asymmetry: One half doesn't match the other.
  • B – Border: The edges are irregular, blurred, or uneven.
  • C – Color: Multiple shades of brown, black, red, white, or blue may be present.
  • D – Diameter: Larger than about 6 mm (roughly the size of a pencil eraser), although melanomas can be smaller.
  • E – Evolving: The mole changes in size, shape, color, or symptoms such as itching or bleeding.


Any changing mole should be evaluated promptly by a dermatologist.


Which Type Is Most Dangerous?


Each type of skin cancer deserves prompt medical attention, but melanoma is generally considered the most dangerous because of its ability to spread to other organs if left untreated. Basal cell carcinoma is usually the least aggressive, while squamous cell carcinoma falls somewhere in the middle, with a greater potential to spread than BCC but generally less than melanoma. Regardless of the type, early diagnosis offers the best chance for successful treatment.


How Can You Protect Your Skin?


Reducing your risk of skin cancer starts with practicing sun safety every day.


Here are a few simple ways to protect your skin:

  • Apply a broad-spectrum sunscreen with SPF 30 or higher daily.
  • Reapply sunscreen every two hours when outdoors and after swimming or sweating.
  • Wear wide-brimmed hats, UV-protective sunglasses, and protective clothing.
  • Seek shade during peak sunlight hours, typically between 10 a.m. and 4 p.m.
  • Avoid tanning beds.
  • Perform monthly skin self-exams.
  • Schedule routine skin cancer screenings with your dermatologist, especially if you're at higher risk.


When Should You See a Dermatologist?


Don't ignore changes in your skin. Schedule an appointment if you notice:

  • A new or changing mole
  • A sore that doesn't heal
  • A spot that bleeds repeatedly
  • A lesion that itches, hurts, or crusts
  • Any growth that looks different from your other moles or spots


Early evaluation can make a significant difference in treatment outcomes.


Early Detection Can Save Lives


Understanding the three main types of skin cancer empowers you to recognize potential warning signs and seek care before the disease progresses. Whether it's a slow-growing basal cell carcinoma, a more aggressive squamous cell carcinoma, or a potentially life-threatening melanoma, regular skin checks and routine dermatology visits remain your best defense. If you're due for a skin examination or have noticed a suspicious spot, schedule an appointment at Skin Dermatology and Cosmetic Services with Dr. Ross Wheeler.

A skin cancer diagnosis can leave you with many questions, especially when it comes to choosing the right treatment. While surgery is often the standard approach for many skin cancers, it isn't the best option for everyone. Some patients may have medical conditions that make surgery more difficult, while others are concerned about scarring or treating cancers in highly visible areas such as the face. One treatment option that has gained attention in recent years is the SRT-100 Vision® , an advanced form of superficial radiation therapy designed to treat certain non-melanoma skin cancers without surgery. If you're exploring your treatment options, understanding how the SRT-100 Vision works, who may benefit from it, and what to expect during treatment can help you make a more informed decision. What Is the SRT-100 Vision®? The SRT-100 Vision is a specialized superficial radiation therapy (SRT) system used to treat certain types of non-melanoma skin cancer. It delivers low-energy X-rays that target cancer cells near the surface of the skin while minimizing exposure to the healthy tissue underneath. Unlike traditional radiation therapy used to treat cancers deeper in the body, superficial radiation therapy is designed specifically for skin conditions located close to the skin's surface.One of the unique features of the SRT-100 Vision is its use of high-frequency ultrasound imaging. This technology allows providers to visualize the skin lesion before, during, and after treatment, helping guide treatment planning and monitor the response over time. What Conditions Can the SRT-100 Vision Treat? The SRT-100 Vision is commonly used to treat certain non-melanoma skin cancers , including: Basal cell carcinoma (BCC) Squamous cell carcinoma (SCC) Squamous cell carcinoma in situ (Bowen's disease) Your Dermatologist will determine whether your skin cancer is an appropriate candidate based on its type, size, location, and depth. It's important to note that melanoma is generally not treated with superficial radiation therapy . Melanoma typically requires a different treatment approach, often involving surgical excision and, in some cases, additional therapies. How Does the SRT-100 Vision Work? The SRT-100 Vision delivers carefully controlled, low-dose radiation directly to the affected area. Radiation damages the DNA inside cancer cells, preventing them from continuing to grow and divide. Over time, the body naturally removes these damaged cells, allowing healthy tissue to heal. Because the radiation penetrates only a short distance beneath the skin, surrounding healthy tissue receives much less exposure than it would with deeper forms of radiation therapy. The addition of ultrasound imaging helps your provider measure the depth of the lesion and monitor treatment progress throughout your care. Who May Be a Good Candidate? The SRT-100 Vision may be an excellent option for patients who: Have basal cell carcinoma or squamous cell carcinoma Prefer to avoid surgery Are not good surgical candidates because of certain medical conditions Have skin cancers in cosmetically sensitive areas such as the nose, ears, eyelids, lips, or scalp Are concerned about surgical scars Have multiple skin cancers requiring treatment Every patient's situation is unique, and your Dermatologist will determine whether superficial radiation therapy is appropriate for your specific diagnosis. What Are the Benefits of the SRT-100 Vision? One of the reasons many patients are interested in the SRT-100 Vision is that it offers several potential advantages over surgery in selected cases. Non-Surgical Treatment - The SRT-100 Vision does not require incisions, stitches, or skin grafts. For patients who wish to avoid surgery or cannot safely undergo an operation, this may provide an effective alternative. Excellent Cosmetic Outcomes - Because no tissue is surgically removed, many patients experience excellent cosmetic results after treatment. This can be particularly beneficial when treating skin cancers on highly visible areas of the face. No General Anesthesia - Treatment does not require general anesthesia or sedation. Most patients remain awake and comfortable throughout each session. Minimal Downtime - Most people are able to return to their normal daily activities immediately after each appointment. There is typically no prolonged recovery period associated with treatment. Image-Guided Precision - The built-in ultrasound imaging helps providers evaluate the lesion and tailor treatment based on its size and depth, allowing for a more personalized approach. What Happens During Treatment? Before treatment begins, your Dermatologist will examine the skin cancer and may use ultrasound imaging to evaluate the lesion. Each treatment session is relatively short. During your appointment: The treatment area is positioned beneath the device. The machine delivers low-energy radiation directly to the lesion. You should not feel pain during the treatment itself. Once the session is complete, you can usually resume your normal activities. Unlike surgery, there are no stitches to care for and no surgical wound to heal. How Many Treatments Are Needed? Superficial radiation therapy is not completed in a single visit. Most patients receive a series of treatments over several weeks. The exact number of sessions depends on factors such as: The type of skin cancer The size of the lesion The depth of the lesion Its location Your individualized treatment plan Your provider will explain your recommended treatment schedule before therapy begins. Are There Side Effects? Like any medical treatment, superficial radiation therapy can cause side effects. Most reactions are limited to the treated area and may include: Mild redness Dryness Skin irritation Peeling Temporary darkening or lightening of the skin These reactions often improve after treatment is completed. Your Dermatologist will provide instructions for caring for the treated area throughout your treatment course. How Effective Is the SRT-100 Vision? Clinical studies have shown that superficial radiation therapy can be highly effective for appropriately selected cases of basal cell carcinoma and squamous cell carcinoma. Success depends on selecting the right patients and ensuring careful follow-up after treatment. Even after successful treatment, regular skin examinations remain important because individuals who have had one skin cancer have a higher risk of developing additional skin cancers in the future. Is Surgery Still the Best Option? For many patients, surgical removal—particularly Mohs surgery—remains the preferred treatment for certain skin cancers because it allows the cancer to be removed and examined immediately. However, surgery is not the best choice for every patient. Factors such as age, medical history, cancer location, cosmetic concerns, and personal preferences all play a role in determining the most appropriate treatment. Your Dermatologist can discuss the benefits and limitations of surgery, superficial radiation therapy, and other available treatments to help you make an informed decision. The SRT-100 Vision represents an innovative, non-surgical approach to treating certain types of non-melanoma skin cancer. By combining superficial radiation therapy with advanced ultrasound imaging, it allows providers to deliver precise treatment while preserving surrounding healthy tissue. For patients who are not candidates for surgery—or who simply prefer a non-invasive option—the SRT-100 Vision may offer an effective treatment with minimal downtime and excellent cosmetic results. If you've been diagnosed with basal cell carcinoma or squamous cell carcinoma, call Skin Dermatology and Cosmetic Services at 386-256-1969 and schedule a consultation to see whether the SRT-100 Vision is an appropriate option for your individual needs. Together, you can develop a treatment plan that prioritizes both your health and your quality of life!

Your skin is your body's largest organ and serves as the first line of defense against environmental damage. Yet many people overlook the importance of routine skin examinations until they notice a concerning mole, growth, or skin change. A total body skin exam is one of the most effective ways to detect skin cancer early and monitor your overall skin health. Whether you have a history of skin cancer or simply want to be proactive about your health, regular skin exams can play a critical role in prevention and early detection. What Is a Total Body Skin Exam? A total body skin exam is a comprehensive evaluation of your skin performed by a dermatologist or qualified healthcare provider. During the examination, your provider carefully inspects your skin from head to toe, including areas that may be difficult for you to see on your own, such as the scalp, back, and behind the ears. The goal is to identify any unusual moles, lesions, growths, or changes that could indicate skin cancer or other skin conditions requiring treatment. Early Detection Saves Lives One of the most important reasons to schedule a total body skin exam is the early detection of skin cancer. When detected in its earliest stages, many forms of skin cancer are highly treatable. Melanoma, the deadliest form of skin cancer, can develop quickly and spread to other parts of the body if left untreated. However, when melanoma is caught early, treatment outcomes are significantly improved. A professional skin exam can help identify suspicious spots before they become more serious health concerns. Skin Cancer Can Develop in Unexpected Places Many people assume skin cancer only develops in areas frequently exposed to the sun. While sun exposure is a major risk factor, skin cancer can appear virtually anywhere on the body. Commonly overlooked areas include: The scalp Between the toes The soles of the feet Behind the ears Under the nails The groin area The back Because these areas are difficult to examine yourself, a total body skin exam provides an added layer of protection. Not All Skin Cancers Are Easy to Spot Skin cancer does not always look like a dark mole. Some cancers may appear as: A pearly bump A non-healing sore A scaly patch A pink growth A lesion that bleeds easily A mole that changes in size, shape, or color Dermatologists are trained to recognize subtle warning signs that may not be obvious to the untrained eye. Monitoring Changes Over Time Your skin naturally changes as you age. However, some changes may indicate an underlying problem. Regular skin exams allow your dermatologist to establish a baseline and monitor moles and lesions over time. Tracking changes can help identify concerns before they become more advanced. Patients with numerous moles, atypical moles, or a history of sun damage particularly benefit from ongoing monitoring. Who Should Get a Total Body Skin Exam? While everyone can benefit from periodic skin evaluations, certain individuals may be at higher risk for skin cancer, including those who: Have a personal or family history of skin cancer Have fair skin, light eyes, or light hair Spend significant time outdoors Have a history of tanning bed use Have experienced frequent sunburns Have many moles or atypical moles Have a weakened immune system If you fall into any of these categories, your dermatologist may recommend more frequent examinations. Peace of Mind for Your Skin Health A total body skin exam is not only about detecting cancer. It can also provide reassurance about benign moles, spots, and other skin changes that may be causing concern. Knowing that your skin has been thoroughly evaluated by a professional can provide valuable peace of mind and help you feel confident about your skin health. What to Expect During Your Appointment Many patients are surprised to learn that a total body skin exam is quick, painless, and non-invasive. During the visit, your dermatologist will: Review your medical and family history Discuss any specific concerns Examine your skin from head to toe Evaluate any suspicious lesions Recommend monitoring, treatment, or biopsy if needed The entire appointment often takes only a short amount of time but can have a lasting impact on your health. The Bottom Line A total body skin exam is one of the simplest and most effective tools for protecting your skin and detecting skin cancer early. Because many skin cancers can develop without noticeable symptoms, routine examinations are an important part of preventive healthcare. By scheduling regular skin exams and paying attention to changes in your skin, you can take an active role in maintaining your health and improving the chances of early detection when treatment is most effective.

Why You Should See a Dermatologist Are you concerned about your skin's health? Do you have any moles, rashes, or other skin issues that worry you? If so, it may be time to see a dermatologist. A dermatologist is a medical professional who specializes in diagnosing and treating conditions related to the skin, hair, and nails.While many people may think of dermatologists as only necessary for severe cases of acne or psoriasis, there are many reasons why someone might want to visit one. For example: - To get an accurate diagnosis for an unusual rash or spot on their skin - To receive treatment for chronic acne that hasn't responded well to over-the-counter remedies - To discuss concerns about signs of aging on their face (such as wrinkles) - To get advice on how to protect themselves from sun damage If any of these sound like something that applies to you, then seeing a dermatologist could be beneficial. What Age Should You Start Seeing a Dermatologist? You might assume that only older adults need to see dermatologists. However, the truth is that it's never too early (or late) to start taking care of your skin. For children and teenagers with persistent acne or eczema flare-ups, visiting a dermatologist can help them manage these conditions more effectively. Additionally, young adults who are interested in anti-aging treatments such as Botox injections may benefit from consulting with a skincare specialist earlier rather than later. Skin cancer rates increase with age; catching potential problems early can save lives. Benefits of Seeing a Dermatologist Early One of the main advantages of seeing a dermatologist early is that they can help you establish good skincare habits. For example, if you're prone to acne breakouts, your dermatologist may be able to recommend a gentle cleanser and moisturizer that won't aggravate your skin. Additionally, some people are genetically predisposed to certain skin conditions (such as rosacea or psoriasis). If you know this ahead of time, you can work with your dermatologist on developing a treatment plan before symptoms start appearing.
