What Is Skin Cancer?
Skin cancer occurs when abnormal skin cells grow uncontrollably, often triggered by sun exposure or other factors. It can appear on sun-exposed areas like the face, ears, neck, or arms, but no part of the body is immune. The three most common types are:
- Basal Cell Carcinoma (BCC): The most common form, often appearing as pearly or waxy bumps, scar-like lesions, or bleeding sores. It’s slow-growing but can cause local damage if untreated, especially on the face or neck.
- Squamous Cell Carcinoma (SCC): Often presents as scaly, crusty lesions or red, firm nodules. It may spread if not addressed early, particularly in sun-damaged skin.
- Melanoma: Appearing as asymmetrical moles, dark spots with irregular borders, or lesions that change in size, shape, or color. Early detection is critical to prevent metastasis, as it can spread to lymph nodes or organs.
While basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) make up the vast majority of skin cancers—accounting for millions of cases annually in the U.S.—they are less likely to spread and are highly treatable when detected early. Melanoma, though rarer (representing about 1% of skin cancers), is far more aggressive and can be life-threatening if it advances, with over 104,000 invasive cases and an estimated 212,200 total melanoma diagnoses (including in situ) projected for 2025 in the U.S. Prompt diagnosis and treatment are essential for all types to prevent complications and improve outcomes, and our Phoenix dermatologists specialize in tailored, evidence-based care to address your unique needs.
What Puts You at Risk for Skin Cancer?
Phoenix’s sunny climate puts residents at higher risk, but other factors also play a role. According to the Skin Cancer Foundation, key risk factors include:
- Unprotected Sun Exposure: UV rays from the sun damage skin cells, especially in sunny areas like Phoenix.
- Tanning Bed Use: Artificial UV exposure significantly increases risk, especially in young adults.
- Family or Personal History: A history of skin cancer in you or your family raises your odds.
- Fair SkinLighter skin types burn more easily, increasing susceptibility.
- Many Moles: Having numerous or atypical moles heightens melanoma risk.
- History of Sunburns: Severe sunburns, especially in childhood, elevate risk later in life.
- Actinic Keratosis: Precancerous lesions that can develop into SCC if untreated.
- Weakened Immune System: Conditions like HIV or immunosuppressive medications increase vulnerability.
- Radiation or Toxin Exposure: Past radiation therapy or exposure to chemicals like arsenic can contribute.
- Age and Gender: While anyone can develop skin cancer, older adults and men are at higher risk for certain types.
To pinpoint your risk, our dermatologists may recommend lab work or genetic testing, especially if you have a family history or atypical moles, to tailor prevention and screening plans.
What Does Skin Cancer Look Like?
Skin cancer can vary in appearance, depending on the type. Watch for these signs, as noted by the American Academy of Dermatology:
- Scar-like or flat lesions
- Waxy or pearly bumps
- Scaly, crusty patches or red nodules
- Bleeding or scabbing sores that don’t heal
- Large brown spots with dark specks
- Moles that change in size, shape, color, or texture
- Lesions with irregular borders or multiple colors
- Itchy or burning spots
Skin cancer often appears on sun-exposed areas like the face, ears, lips, scalp, neck, chest, arms, hands, or legs, but it can develop anywhere, including under nails or in the mouth. Regular self-checks using the ABCDE rule (Asymmetry, Border irregularity, Color variation, Diameter >6mm, Evolving) can help spot melanoma early.
How Is Skin Cancer Diagnosed?
At Dermatology Associates, our board-certified dermatologists use a thorough approach to diagnose skin cancer for men, women, children, and adults:
- Skin Examination: A detailed inspection of your skin, focusing on suspicious lesions or moles.
- Medical History Review: Assessing risk factors like sun exposure, family history, or immune status.
- Biopsy:A small sample of the lesion is taken and analyzed in a lab to confirm cancer and determine its type.
- Lab Work: Blood tests or genetic screening may be used to identify underlying conditions or risk factors, especially for recurrent or high-risk cases.
This personalized process ensures an accurate diagnosis and a treatment plan tailored to your needs, whether you’re dealing with BCC, SCC, melanoma or other rarer skin cancer.
Top Skin Cancer Treatments at Dermatology Associates
Our team at Dermatology Associates offers cutting-edge, evidence-based treatments to eliminate skin cancer and minimize recurrence, customized for each patient. Here’s a breakdown by type:
- Treatments for Basal Cell Carcinoma (BCC): BCC is often treated with excision, electrodessication and curettage, or Mohs surgery. For advanced or inoperable BCC, smoothened inhibitors like vismodegib or sonidegib (FDA-approved for locally advanced or metastatic BCC) may be prescribed to block the Hedgehog signaling pathway, shrinking tumors or slowing growth, with response rates up to 60% in trials. For patients who are not ideal candidates for surgery due to health conditions or other factors, localized radiation therapy may be used to effectively target and destroy BCC cells, offering a non-invasive alternative with minimal recovery time. Topical creams like imiquimod may be used for superficial BCC. Basal Cell Carcinomas rarely spreads but can invade nearby tissue, so early removal prevents disfigurement. Cure rates exceed 95% with early intervention.
- Treatments for Squamous Cell Carcinoma (SCC): SCC is treated with excision, electrodessication and curettage, or Mohs surgery. For patients unsuitable for surgery due to health conditions, localized radiation therapy provides a non-invasive option to eliminate SCC cells with minimal downtime. For advanced or metastatic SCC, immunotherapy with PD-1 inhibitors like cemiplimab (FDA-approved in 2018 for metastatic SCC) may be used to boost the immune system’s ability to attack cancer cells, achieving response rates of about 50% in clinical studies (Mayo Clinic). SCC can metastasize if advanced, so radiation or systemic therapies may be added for larger tumors. Cure rates exceed 95% with early intervention.
- Treatments for Melanoma: Surgical excision is primary, with wider margins for deeper melanomas. Advanced or metastatic melanoma may involve sentinel lymph node biopsy, immunotherapy with PD-1 inhibitors like pembrolizumab or nivolumab (FDA-approved for advanced melanoma), which enhance immune response to target cancer cells, achieving 5-year survival rates of 40–50% in metastatic cases, or targeted therapy for BRAF mutations (e.g., vemurafenib). Melanoma requires multidisciplinary care with oncologists to address potential spread.
Specific treatments include:
- Excision: Surgically removing the cancerous lesion and a margin of healthy tissue to ensure complete removal. Typically done in-office with local anesthesia.
- Mohs Surgery: Performed by Dr. Rajiv Kwatra, our fellowship-trained Mohs surgeon with over 41,500 treated cases. Developed by Dr. Frederic Mohs about 50 years ago, this precise, layer-by-layer technique is ideal for large, aggressive, or recurrent BCC and SCC, especially on the face, ears, or other cosmetically sensitive areas. Dr. Kwatra completed his Mohs fellowship at the Medical University of South Carolina after residency at Ohio State University, bringing expertise from treating over 1,500 cases during training. It minimizes scarring and has a high cure rate (up to 99% for early BCC/SCC, per the Skin Cancer Foundation). While less common for melanoma, it may be used in select cases.
- Cryotherapy (Freezing): Liquid nitrogen freezes and destroys precancerous lesions like actinic keratosis. Quick and effective for superficial lesions.
- Electrodessication and Curettage: Uses an electric current and scraping to remove small BCCs or SCCs, often completed in one visit.
- Laser Therapy: Targets precancerous spots, promoting healing with minimal damage to surrounding tissue.
- Advanced Treatments: For advanced or metastatic cancers, treatments like chemotherapy, radiation therapy, immunotherapy (e.g., PD-1 inhibitors like pembrolizumab or cemiplimab), or targeted therapies (e.g., smoothened inhibitors for BCC) may be recommended. These are coordinated with oncologists for comprehensive care.
Regular follow-ups ensure early detection of recurrences, especially for high-risk patients. Our treatments are safe and effective for adults and children, with pediatric cases managed under close supervision.
