Skin Cancer Screening: What Happens and How to Prepare
A skin cancer screening is a visual examination of your entire skin surface by a dermatologist. It typically takes 10-15 minutes and can detect skin cancers that you might not notice on your own - especially in hard-to-see areas like the back, scalp, and between toes.
What happens during a screening
You undress and put on a gown. The dermatologist systematically examines your entire skin surface - scalp, face, neck, chest, arms, hands, back, legs, feet, and nails. They may use a dermatoscope (handheld magnifying device with polarized light) to examine specific moles more closely.
The entire process takes 10-15 minutes. If the dermatologist finds anything concerning, they may recommend monitoring (with photos), biopsy (removing a small sample), or immediate excision.
How to prepare
Remove nail polish from fingernails and toenails so the dermatologist can check for subungual melanoma. Wear your hair loose so the scalp can be examined. Note any spots that concern you so you can point them out. If you have been monitoring a changing mole, bring photos showing the change over time.
Do not wear heavy makeup on the day of your screening. Do not be embarrassed - dermatologists examine skin for a living.
How often to get screened
General population: annual screening is recommended by many dermatologists, though screening guidelines vary. High-risk individuals (history of melanoma, many moles, fair skin, family history, immunosuppression): every 3-6 months. After a skin cancer diagnosis: follow-up every 3-6 months for the first 2-3 years, then annually.
Between professional screenings, perform monthly self-examinations at home.
Cost and insurance
A screening visit typically costs $100-300 without insurance. Many insurance plans cover an annual skin cancer screening as preventive care, especially if you have risk factors. Check with your insurance provider. Some dermatologists and skin cancer organizations offer free screening events, particularly during Melanoma Awareness Month (May).
Self-screening between visits
Monthly self-examination is recommended for everyone. Use a full-length mirror and hand mirror to examine all body surfaces. Follow a systematic routine so you do not miss any areas. Document your moles with photos so you can track changes over time.
Self-screening catches the majority of melanomas - studies show that self-detected melanomas tend to be thinner (earlier stage) than those found incidentally.
When self-screening is not enough
Some skin cancers occur in places you cannot easily see: the scalp, back, buttocks, and between toes. Dermoscopy reveals subsurface structures invisible to the naked eye. Some melanomas lack obvious ABCDE features. For these reasons, professional screening is an important complement to self-examination, not a replacement.
