Effective Basal Cell Carcinoma (BCC) Treatments

Expert Care To Detect, Treat, and Manage BCC for Healthy Skin

Basal cell carcinoma is the most common form of skin cancer and the most frequently occurring cancer overall. It begins in the basal cells, which are found at the bottom of the epidermis, the skin’s outer layer. These cells play a role in producing new skin cells, and when they become damaged, abnormal growth can occur.

For many patients, learning about basal cell carcinoma often leads to questions about basal cell carcinoma (BCC) treatment and what the next steps may look like. Understanding how this condition develops and behaves helps clarify why timely evaluation and appropriate care matter.

What Causes BCC?

Basal cell carcinoma is primarily caused by cumulative exposure to ultraviolet (UV) radiation. This exposure most often comes from sunlight, though indoor tanning devices also contribute. UV radiation damages the DNA within skin cells. 

Over time, repeated damage can interfere with normal cell growth and repair, allowing abnormal basal cells to multiply and form a cancer.

In many cases, basal cell carcinomas grow slowly and remain confined to the skin. They rarely spread to other parts of the body. Even so, BCC should never be ignored. When left untreated, these tumors can grow wider and deeper into the surrounding tissue.

On the contrary, basal cell carcinoma that is identified and treated at an early stage entails a typically straightforward and highly effective treatment. Most early BCCs can be removed completely with minimal impact on surrounding tissue. Addressing the cancer promptly also lowers the likelihood of visible scarring or functional problems, such as changes to the nose, eyelids, or ears. 

Risk Factors

While anyone can develop basal cell carcinoma, certain factors increase risk:

• Chronic Sun Exposure: Long-term, unprotected exposure to sunlight or tanning beds remains the strongest risk factor. Individuals who spend a significant amount of time outdoors or have a history of frequent sunburns are at a higher risk.
• Fair Skin: Individuals with light skin that burns easily, freckles, blond or red hair, or light-colored eyes have less melanin to protect against UV radiation. This makes them more susceptible to BCC than people with darker skin tones.
• Older Age: Basal cell carcinoma occurs more often in adults over age 50 due to cumulative sun exposure over many years. Younger adults can still develop BCC, especially after intense UV exposure earlier in life.
• Genetic Predisposition: A family history of skin cancer can increase risk. Certain inherited conditions, such as Gorlin syndrome, can lead to the development of multiple basal cell carcinomas over time.

Other Factors: A weakened immune system, prior radiation therapy to the skin, or areas of chronic injury or scarring can also increase susceptibility. However, these factors are less common.

Signs and Symptoms of BCC

Basal cell carcinoma can manifest in various forms. In many cases, it begins as a subtle change on the skin that develops slowly over time. 

Because these changes are often painless and gradual, they can be easy to overlook. Knowing what to watch for can help you recognize potential concerns earlier and seek evaluation sooner.

Common warning signs of basal cell carcinoma include the following:

Diagnosis and Evaluation

If you notice a concerning spot on your skin, scheduling a prompt visit with a dermatologist is an important next step. Early evaluation enables an accurate diagnosis and helps limit the extent of basal cell carcinoma (BCC) treatment that may be necessary. 

At Connolly Dermatology, our board-certified dermatologists have extensive experience identifying and diagnosing skin cancers. During your visit, we carefully examine the area of concern to confirm whether BCC is present and understand the full scope of the lesion. 

Thorough Skin Examination and Dermoscopy

We begin with a visual examination of the area that concerns you. Your dermatologist will also examine the rest of your skin, since skin cancer can appear in more than one location. 

In many cases, a handheld magnifying device called a dermatoscope is used to look at the lesion more closely. Dermoscopy uses polarized light and magnification to reveal features beneath the skin surface that are not visible to the naked eye. Certain patterns of blood vessels, texture, or pigmentation can suggest basal cell carcinoma and help guide the next steps.

Your dermatologist will also review your skin health history. This includes questions about sun exposure, tanning bed use, prior skin cancers, family history, and any recent changes you have noticed. 

Skin Biopsy for Confirmation

If a lesion appears suspicious for basal cell carcinoma, a skin biopsy is performed to confirm the diagnosis. 

The biopsy is a minor procedure that can be completed during your office visit. The area is first numbed with a local anesthetic to keep you comfortable. A small portion of the lesion, or in some cases the entire lesion, is then removed. The tissue sample is sent to a laboratory, where a pathologist examines it under a microscope to look for cancer cells.

The procedure itself is brief and usually well-tolerated. Afterward, your dermatologist will explain how to care for the biopsy site while it heals and discuss when you can expect your results. 

Assessment of Tumor Extent

If basal cell carcinoma is confirmed, the next step is evaluating the tumor’s size, depth, and location. The pathology report may also identify the subtype of BCC, such as nodular or superficial, which helps guide treatment planning.

Treatment Options for BCC

On the bright side, basal cell carcinoma is very treatable, especially when caught early. In most cases, treatment is effective and focused on removing the cancer while preserving as much healthy skin as possible. 

At Connolly Dermatology, treatment for basal cell carcinoma (BCC) is tailored to the tumor’s characteristics and each patient’s overall health and preferences.

Surgical Treatment

Surgery is the most common approach for treating basal cell carcinoma. It allows the dermatologist to physically remove the cancer and, in many cases, confirm that all abnormal cells have been cleared.

Excisional Surgery 

Excisional surgery involves removing the basal cell carcinoma along with a small margin of surrounding normal skin. This procedure is typically performed in the office using local anesthesia, which numbs the area while you remain awake and conscious.

After removal, the tissue is sent to a laboratory to confirm that the margins are clear of cancer cells. The wound is then closed with sutures. Once healing is complete, the resulting scar is usually small and becomes less noticeable over time. 

Excisional surgery has a high cure rate, often exceeding 95% for small, early-stage basal cell carcinomas, making it a reliable option for many uncomplicated lesions.

Mohs Micrographic Surgery

Mohs micrographic surgery is a specialized technique used for basal cell carcinomas in areas where preserving healthy tissue is especially important. It is often recommended for cancers on the face, including the nose, ears, eyelids, and lips. Mohs surgery is also considered for larger tumors, recurrent BCCs, or those with aggressive growth patterns.

During Mohs surgery, the tumor is removed in thin layers. Each layer is examined immediately under a microscope to check for cancer cells. This process continues until no cancer remains. By examining the tissue as it is removed, Mohs surgery allows for complete cancer removal while sparing as much normal skin as possible.

Mohs surgery offers the highest cure rate for basal cell carcinoma, reaching up to 99% for first-time tumors. Because only the necessary tissue is removed, it also helps minimize scarring, which is especially valuable in visible or delicate areas.

Non-Surgical Treatment

Not all basal cell carcinomas require surgery. For superficial BCCs that are limited to the top layer of the skin or for small, low-risk lesions, non-surgical treatments may be appropriate.

Topical Medications 

Certain prescription creams and gels are used to treat superficial basal cell carcinomas. Common options include 5-fluorouracil, a topical chemotherapy, and imiquimod, which stimulates the immune system. These medications are applied directly to the affected area over several weeks and gradually destroy cancerous cells in the skin. 

Because this approach does not involve a procedure, it can result in minimal scarring. However, since the treated tissue is not removed and examined, cure rates tend to be lower than with surgical options, and careful follow-up remains important.

Superficial Radiotherapy (SRT) 

Superficial radiotherapy is a non-surgical treatment option used in selected cases of basal cell carcinoma. It involves delivering low-dose radiation directly to the affected area to destroy cancer cells while minimizing impact on deeper tissues. 

Treatment is typically delivered over a series of short outpatient sessions. Each session lasts only a few minutes and does not require anesthesia. Over time, the treated skin heals as the cancer cells are eliminated. 

This approach may be considered for patients who are not good candidates for surgery due to medical factors, lesion location, or personal preference.

Photodynamic Therapy (PDT) 

Photodynamic therapy is used in selected cases of superficial basal cell carcinoma, often when the lesion is located on areas such as the face or scalp. 

Treatment starts with the application of a light-sensitizing medication to the affected area. After an incubation period, the skin is exposed to a specific wavelength of light, which activates the medication and destroys cancer cells.

Following treatment, the area typically crusts and heals gradually over time. However, patients are advised to avoid sunlight for a short period post-treatment to prevent irritation of the surrounding skin.

Follow-Up and Monitoring

Follow-up care is essential in managing basal cell carcinoma. Once removed, BCC is usually cured and rarely spreads beyond the skin. However, having one basal cell carcinoma increases the likelihood of developing another skin cancer in the future.

Most patients are advised to have a full-body skin examination at least once a year. More frequent visits may be recommended if there is a history of multiple skin cancers or additional risk factors. During these visits, your dermatologist examines previous treatment sites and looks for new or changing lesions, which helps support early detection and ongoing skin health.

Risk Reduction and Prevention

While basal cell carcinoma can often be treated successfully, taking steps to reduce the risk and identify changes early plays a crucial role in maintaining long-term skin health. 

The following steps offer practical ways to protect your skin and catch potential concerns early: 

• Practice Sun Safety: Limiting exposure to ultraviolet (UV) radiation helps lower the risk of skin cancer. Try to avoid direct sun exposure during peak hours, generally between 10 a.m. and 4 p.m.
• Use Sunscreen Daily: Apply a broad-spectrum sunscreen with an SPF of 30 or higher to all exposed skin each day. This includes days that feel cool or cloudy, as UV exposure still occurs throughout the year. Regular sunscreen use helps reduce the DNA damage in skin cells that can lead to basal cell carcinoma over time.
• Wear Protective Clothing and Gear: Cover up with sun-protective attire. Long-sleeved shirts, long pants, and fabrics with a tight weave or an official UPF (Ultraviolet Protection Factor) rating can help block UV radiation. 
• Avoid Indoor Tanning Beds: Tanning beds and sun lamps emit concentrated UV radiation that increases the risk of skin cancer. Avoiding these artificial sources reduces unnecessary exposure and supports healthier skin over the long term.
• Perform Regular Skin Self-Exams: Checking your skin once a month helps you become familiar with what is normal for you. Look from head to toe for new growths or changes in existing spots. Use mirrors to examine areas that are hard to see. 

Schedule Routine Professional Skin Exams: Regular skin checks with a healthcare provider should be part of ongoing skin care. Many adults benefit from a full-body skin exam once a year. More frequent visits may be recommended if you have additional risk factors or a history of skin cancer.
