What is skin checks & skin cancer?
Skin cancer is the most common cancer in the United States. The main types are basal cell carcinoma, squamous cell carcinoma and melanoma. Ultraviolet exposure from the sun and tanning beds is the leading risk factor — an area Dr. Wei studied for many years in his research on UV radiation and skin cancer.
Skin cancer can occur in every skin tone. In darker skin it is often found later and may appear on the palms, soles, nails or other less sun-exposed areas, so regular checks matter for everyone.
When to see a dermatologist
- A mole is new, changing, itching or bleeding
- A spot looks different from your other moles (the “ugly duckling” sign)
- You have a sore that doesn't heal within a few weeks
- You have a personal or family history of skin cancer
- You have fair skin, many moles, a history of sunburns or tanning bed use
How we evaluate
During a skin check your dermatologist examines your skin from scalp to toes, including areas that are hard to see yourself, and may use a dermatoscope to look closely at individual spots. We use the ABCDEs of melanoma — Asymmetry, Border, Color, Diameter and Evolving — along with your history to decide which lesions need attention.
If a spot looks suspicious, a quick in-office biopsy may be recommended so it can be examined under a microscope.
Treatment options at DR WW Dermatology
- Full-body skin exam. A head-to-toe check, recommended at an interval based on your personal risk.
- Focused spot evaluation. A visit to look at a single new or changing mole or growth.
- Biopsy. Removal of a small sample or the whole lesion for laboratory diagnosis.
- Treatment and follow-up. Removal of precancerous or cancerous lesions as appropriate, or referral for specialized surgery, with a follow-up schedule tailored to you.
Not every option suits every patient, and availability of specific devices varies by office. Your dermatologist will recommend a plan after an in-person evaluation.
What to expect: treatment, recovery and aftercare
A full-body skin exam usually takes about 10 to 15 minutes. If a biopsy is performed, the area is numbed first and typically heals within one to two weeks; your results are reviewed with you once available. Between visits, a monthly self-check and daily sun protection are the best habits you can build.
Frequently asked questions
How often should I have a skin check?
It depends on your risk. People with a history of skin cancer, many moles or a strong family history are often checked once or twice a year. Your dermatologist will recommend an interval for you.
Do I need to undress for a skin exam?
For a full-body exam you will change into a gown so the dermatologist can see all areas of skin. You may ask to skip any area or have a chaperone present.
Does a biopsy hurt?
The area is numbed with a small injection first, so most patients feel only a brief pinch.
