How Do Dermatologists Do a Full Body Check for Skin Cancer?
Dermatologists conduct a thorough full body skin exam to identify potentially cancerous or precancerous lesions by systematically inspecting the entire skin surface, from head to toe, using both visual inspection and, in some cases, specialized tools like a dermatoscope.
Why is a Full Body Check Important?
The importance of regular full body checks by a dermatologist cannot be overstated. Skin cancer is the most common type of cancer in the United States, but it is also highly treatable when detected early. Self-exams are valuable, but dermatologists are trained to recognize subtle signs of skin cancer that individuals might miss.
- Early Detection: Finding skin cancer early significantly improves the chances of successful treatment.
- Improved Prognosis: Early-stage melanoma, for example, has a much higher survival rate than late-stage melanoma.
- Risk Assessment: A dermatologist can assess your individual risk factors for skin cancer and recommend appropriate screening intervals.
- Peace of Mind: Even if no suspicious lesions are found, a full body check can provide peace of mind.
The Full Body Check Process: A Step-by-Step Guide
How do dermatologists do a full body check? Here’s a breakdown of the typical process:
-
Medical History: The dermatologist will begin by taking a detailed medical history, including information about your personal and family history of skin cancer, sun exposure habits, previous skin conditions, and any medications you are taking.
-
Preparation: You will be asked to undress completely and put on a medical gown or sheet. The dermatologist will ensure your privacy and comfort throughout the exam.
-
Visual Inspection: The dermatologist will systematically examine your entire skin surface, including:
- Scalp (using a comb to part the hair)
- Face, including ears, nose, and lips
- Neck and chest
- Arms and hands, including fingernails
- Back and abdomen
- Legs and feet, including toenails
- Genital area and buttocks (if consented to and relevant)
-
Dermatoscopy: For suspicious lesions, the dermatologist may use a dermatoscope – a handheld magnifying device with a light source – to examine the skin more closely. This allows them to see structures beneath the surface of the skin that are not visible to the naked eye.
-
Documentation: The dermatologist will document the location, size, and characteristics of any moles or lesions of concern. They may also take photographs for comparison at future exams.
-
Biopsy (If Necessary): If the dermatologist identifies a lesion that is suspicious for skin cancer, they may recommend a biopsy. This involves removing a small sample of the skin and sending it to a laboratory for analysis.
-
Treatment or Referral: If a biopsy confirms skin cancer, the dermatologist will discuss treatment options with you. In some cases, they may be able to treat the cancer themselves. In other cases, they may refer you to a specialist, such as a surgical oncologist.
ABCDEs of Melanoma
A useful tool dermatologists (and patients) use to assess moles is the ABCDE method:
| Feature | Description |
|---|---|
| Asymmetry | One half of the mole does not match the other half. |
| Border | The edges of the mole are irregular, notched, or blurred. |
| Color | The mole has uneven colors, such as black, brown, tan, red, white, or blue. |
| Diameter | The mole is larger than 6 millimeters (about the size of a pencil eraser). |
| Evolving | The mole is changing in size, shape, color, or elevation, or is developing new symptoms like bleeding, itching, or crusting. |
Common Mistakes to Avoid During a Self-Exam
While dermatologist-performed full body checks are crucial, performing self-exams regularly between professional screenings is also recommended. However, it’s important to avoid these common mistakes:
- Neglecting Hard-to-See Areas: Don’t forget to check your scalp, back, and between your toes. Use a mirror or ask a partner for help.
- Not Keeping Track of Moles: Regularly monitor your moles for any changes in size, shape, color, or texture.
- Ignoring New or Unusual Spots: Any new or unusual spots, even if they don’t fit the ABCDE criteria, should be evaluated by a dermatologist.
- Thinking All Moles are Normal: Even moles that seem “normal” can sometimes be cancerous.
Preparing for Your Full Body Check Appointment
Preparing for your full body check is simple:
- Remove nail polish and artificial nails.
- Do not wear makeup or jewelry.
- Wear your hair down so the dermatologist can easily examine your scalp.
- Make a list of any concerns or questions you have.
- Be prepared to discuss your medical history and sun exposure habits.
Frequently Asked Questions (FAQs)
What should I expect during my first full body check?
You can anticipate a thorough but painless examination of your skin. The dermatologist will ask about your medical history and sun exposure. They will explain each step of the exam and answer any questions you have. The process is designed to be as comfortable and informative as possible.
How often should I get a full body check?
The frequency of full body checks depends on your individual risk factors. People with a personal or family history of skin cancer, numerous moles, or a history of excessive sun exposure should get checked more frequently, typically every 6 to 12 months. Others may only need a check every 1-2 years, or as recommended by their dermatologist.
Can I wear makeup or nail polish to my appointment?
It’s best to avoid wearing makeup or nail polish to your appointment. Makeup can obscure moles and lesions on your face, and nail polish can hide potential signs of skin cancer under your nails.
Does a full body check hurt?
No, a full body check is not painful. The dermatologist will visually inspect your skin and may use a dermatoscope to examine suspicious lesions more closely, but this does not cause pain. A biopsy may cause minimal discomfort, but it’s a quick and routine procedure.
What happens if the dermatologist finds something suspicious?
If the dermatologist finds something suspicious, they may recommend a biopsy. This involves removing a small sample of the skin and sending it to a laboratory for analysis. The results of the biopsy will help determine whether the lesion is cancerous.
How long does a full body check usually take?
A full body check typically takes about 20-30 minutes. The exact length of the exam will depend on the number of moles you have and whether the dermatologist needs to perform any additional procedures, such as a dermoscopy or biopsy.
Are there any risks associated with a full body check?
There are very few risks associated with a full body check. The main risk is the possibility of a false positive biopsy result, which can lead to unnecessary anxiety and further testing. However, the benefits of early detection outweigh this risk.
What if I’m self-conscious about undressing in front of the dermatologist?
It’s perfectly normal to feel self-conscious about undressing in front of a dermatologist. Dermatologists are professionals and are accustomed to seeing patients in this state. They will do their best to make you feel comfortable and will respect your privacy. You can also ask for a chaperone to be present during the exam.
Can a full body check detect all types of skin cancer?
A full body check is designed to detect all types of skin cancer, including melanoma, basal cell carcinoma, and squamous cell carcinoma. However, some skin cancers can be difficult to detect, especially if they are located in hard-to-see areas or are very small.
What should I do if I find a suspicious mole between full body checks?
If you find a suspicious mole or lesion between full body checks, you should schedule an appointment with your dermatologist as soon as possible. Don’t wait until your next scheduled checkup.
Is a full body check covered by insurance?
Most health insurance plans cover full body checks, especially if you have a personal or family history of skin cancer or other risk factors. Check with your insurance provider to confirm your coverage.
How can I protect my skin between full body checks?
Protect your skin by:
- Seeking shade, especially during peak sun hours (10 AM to 4 PM).
- Wearing protective clothing, such as long sleeves, pants, and a wide-brimmed hat.
- Applying sunscreen with an SPF of 30 or higher to all exposed skin every day, even on cloudy days.
- Avoiding tanning beds.
