Mole Evaluation & Removal in Clovis & Fresno, CA
Moles are among the most common skin growths — most adults have between 10 and 40 of them — and the vast majority are completely harmless. But because a small percentage of moles can develop into or serve as early warning signs of melanoma, professional evaluation is always the safest approach when a mole changes, grows, or causes concern. At Dehesa Dermatology, board-certified dermatologist Dr. Luis A. Dehesa provides thorough, expert mole evaluations using advanced dermoscopy and performs safe, precise mole removals for both medical and cosmetic purposes throughout Clovis, Fresno, and the Central Valley.
What Are Moles?
Moles, medically termed melanocytic nevi, are benign growths that form when melanocytes — the pigment-producing cells in the skin — cluster together rather than spreading evenly throughout the skin. Most moles appear during childhood and adolescence, with new ones occasionally developing into early adulthood. Sun exposure can increase the number of moles and influence their pigmentation over time.
A typical benign mole is small (less than 6mm), round or oval-shaped, with smooth, well-defined borders and a uniform tan or brown color. However, not all moles fit this description perfectly — some are raised, some are flesh-colored, and some have irregular features that can be difficult to assess without professional evaluation and dermoscopy.
Atypical or dysplastic nevi are moles with irregular features — larger size, uneven borders, mixed coloration — that carry a slightly elevated risk of melanoma development, particularly in patients with multiple atypical moles or a family history of skin cancer. Patients with atypical moles benefit from a personalized surveillance plan and regular monitoring at Dehesa Dermatology.
When Should a Mole Be Evaluated?
Most dermatologists recommend a full-body skin exam at least once a year for all adults, and more frequently for those with risk factors. Beyond annual exams, seek a prompt evaluation at Dehesa Dermatology if a mole or spot exhibits any of the following:
- Changes in size, shape, or color over weeks or months
- Irregular, blurred, or notched borders
- Multiple colors within a single lesion (brown, black, red, white, or blue)
- Asymmetry — one half looks different from the other
- Diameter larger than 6mm (about the size of a pencil eraser)
- Itching, bleeding, oozing, or crusting that doesn’t resolve
- A mole that looks or feels different from your other moles (the “ugly duckling” sign)
- A new mole that appears after age 40
These are the same ABCDEs we use to evaluate for melanoma — learn more on our melanoma page. When in doubt, it is always better to have it checked than to wait and wonder.
How We Evaluate Moles at Dehesa Dermatology
At Dehesa Dermatology, mole evaluation begins with a thorough full-body skin exam. Dr. Dehesa uses dermoscopy — a hand-held illuminated magnification instrument that allows visualization of subsurface structures not visible to the naked eye — to assess mole architecture, pigment patterns, and vascular features. Dermoscopy significantly improves diagnostic accuracy and helps distinguish benign moles from those requiring biopsy.
If a mole appears suspicious, Dr. Dehesa will recommend a skin biopsy. The sample is sent to an independent dermatopathology laboratory for microscopic analysis. Results are typically available within 7 to 10 business days. If biopsy results confirm melanoma or severe dysplasia, we immediately discuss the next steps in treatment, which may include wide local excision or Mohs surgery.
Mole Removal Options
We perform mole removal at Dehesa Dermatology for both medical and cosmetic reasons. Removal techniques include:
- Shave Excision: A thin blade is used to shave the mole flush with the surrounding skin surface. Ideal for raised, benign moles. Fast, simple, and leaves a flat, often barely visible scar.
- Excisional Surgery: The mole is cut out with a surgical scalpel and the wound is closed with sutures. Required for moles that are suspected or confirmed to be cancerous, to ensure complete removal with adequate margins.
- Punch Biopsy / Removal: A circular punch tool is used to remove small, round moles cleanly. Often combined with diagnostic biopsy in a single procedure.
- Laser Treatment: Used in select cases for flat, cosmetically bothersome benign moles. Not appropriate for moles requiring histologic evaluation. Ask your provider whether laser is an option for your specific mole. Learn more about our laser treatment services.
All removed moles — even those that appear clinically benign — can be submitted for pathological examination at your request. We always recommend biopsy for any mole with atypical features. For moles confirmed to be malignant, including melanoma or other skin cancers, treatment planning begins immediately to ensure prompt, complete care.
Mole Monitoring for High-Risk Patients
Patients with numerous moles, a history of dysplastic nevi, or a personal or family history of melanoma benefit from a structured mole monitoring program. At Dehesa Dermatology, we offer baseline total-body photography and dermoscopic documentation to track moles over time — allowing us to detect subtle changes between visits that might otherwise be missed. This proactive approach is one of the most important tools in melanoma prevention for high-risk individuals in our community.
Frequently Asked Questions About Moles
How do I know if a mole needs to be removed?
A mole should be evaluated — and possibly removed — if it shows any of the ABCDE warning signs: asymmetry, irregular borders, multiple colors, diameter over 6mm, or evolution (change over time). Moles that bleed, itch, or become tender also warrant prompt evaluation. At Dehesa Dermatology, Dr. Dehesa uses dermoscopy to assess moles with precision, allowing him to determine whether removal and biopsy are warranted or whether monitoring is the appropriate approach.
Does mole removal leave a scar?
All skin procedures leave some degree of change to the skin — the goal is to minimize scarring and achieve the most cosmetically favorable outcome possible. Shave excisions typically leave a flat, lighter-colored mark that fades significantly over several months. Excisional removals leave a linear scar. Our team takes meticulous care with technique, wound closure, and post-procedure instructions to optimize healing. For cosmetically sensitive areas, we discuss all options and expected outcomes thoroughly before proceeding.
Can a mole grow back after removal?
If a mole is incompletely removed, some cells may remain and the mole can partially regrow — typically appearing as a flat, irregular, sometimes darker recurrence. This is why complete excision is important for any mole with atypical features. At Dehesa Dermatology, we take every step to ensure complete removal during the initial procedure, and we follow up on pathology results to confirm adequate margins when needed.
Is mole removal covered by insurance?
Mole removal performed for medical reasons — such as evaluation of a suspicious or changing mole — is typically covered by insurance when medically indicated. Cosmetic removal of benign moles that are not medically concerning is generally not covered. Our team can help you understand your specific coverage and submit appropriate documentation for medically necessary procedures. Call (559) 951-9000 for more information.
How long does mole removal take?
Most mole removals are quick, in-office procedures performed under local anesthesia. Depending on the technique, the procedure itself takes between 15 and 45 minutes. You can typically return to normal activities the same day, though strenuous exercise and sun exposure to the treated area should be avoided for a period of time as directed by our team.
What happens if my mole biopsy shows cancer?
If your biopsy shows melanoma or another skin cancer, our team will contact you promptly to discuss the diagnosis and recommended next steps. Treatment depends on the type and stage of cancer — options may include wide local excision, Mohs micrographic surgery, or referral to oncology for advanced cases. You will never receive a concerning diagnosis result without a follow-up call and a clear plan. See our skin cancer treatment page for more information on the full spectrum of care we provide.
