Skin Cancer Screening in Seoul

Skin cancer screening is an examination of the skin for suspicious moles, growths, wounds, or other changes that may require closer evaluation. It may involve a full-body skin examination, dermoscopy, clinical photography, or biopsy of a concerning lesion.

Many spots are harmless, but skin cancer can sometimes resemble an ordinary mole, pimple, scar, or dry patch. Early assessment is especially important when a lesion is new, changing, bleeding, or failing to heal.

Who May Benefit From Screening?

The need and frequency of professional skin checks depend on individual risk rather than one schedule for everyone.

Screening may be particularly helpful for people with:

• A personal history of skin cancer
• A family history of melanoma
• Many moles or unusual-looking moles
• Significant sun exposure
• Repeated blistering sunburns
• Frequent outdoor work or activities
• Previous tanning-bed use
• A weakened immune system
• A changing or symptomatic skin lesion
• Difficulty checking their own skin

People of every skin tone can develop skin cancer. Patients with deeper skin tones should also check the palms, soles, nails, and other areas where changes may be less expected.

Changes That Should Be Examined

A dermatologist should evaluate a spot that:

• Is new or growing
• Changes in shape or color
• Looks different from nearby moles
• Itches, hurts, or bleeds
• Develops repeated crusting
• Heals and then returns
• Remains as a persistent sore
• Appears as a firm or shiny bump
• Forms a rough, scaly patch
• Causes unexplained nail discoloration

Skin cancers do not always look like dark moles. They may also resemble a non-healing wound, pimple, insect bite, scaly plaque, or skin-colored growth.

The ABCDE Signs of Melanoma

The ABCDE guide can help identify changes that deserve medical attention:

• A — Asymmetry: One half looks different from the other
• B — Border: The edges are irregular, blurred, or poorly defined
• C — Color: Several colors or uneven shades are present
• D — Diameter: The spot is increasing in size, although melanoma can be small
• E — Evolving: The size, shape, color, texture, or symptoms are changing

Evolution is particularly important. A mole that has remained stable for years is different from one that has recently enlarged, darkened, become raised, or started bleeding.

What Happens During a Skin Examination?

A dermatologist may examine:

• Scalp and hairline
• Face and ears
• Neck and chest
• Back and abdomen
• Arms and hands
• Legs and feet
• Palms and soles
• Between the fingers and toes
• Nails
• Areas usually covered by clothing

Patients should mention any specific lesion that has changed, even when it appears small or is located in an area not routinely exposed to sunlight.

The doctor may also ask about previous skin cancer, family history, sun exposure, tanning, immune-suppressing medication, and earlier biopsies.

How Dermoscopy Helps

Dermoscopy uses a handheld magnifying instrument with specialized lighting to examine structures beneath the skin’s surface.

It is commonly used to evaluate:

• Moles
• Brown or black spots
• Red or scaly lesions
• Suspected basal cell carcinoma
• Suspected squamous cell carcinoma
• Possible melanoma

In experienced hands, dermoscopy can improve the assessment of pigmented lesions and help distinguish suspicious changes from benign growths. It does not replace biopsy when cancer cannot be ruled out.

Will Every Mole Be Removed?

Most moles do not need removal.

The dermatologist may recommend:

• Routine observation
• Clinical photography
• Short-term follow-up
• Digital mole monitoring
• Partial sampling
• Complete removal for biopsy

A lesion should not be removed cosmetically with a laser before its diagnosis is clear. Laser destruction may eliminate visible tissue without providing an adequate specimen for pathological examination.

Patients should not cut, burn, or remove suspicious moles at home. Improper removal can cause infection, scarring, and delayed diagnosis.

When a Biopsy Is Needed

A biopsy removes part or all of a suspicious lesion so that it can be examined under a microscope.

The method depends on:

• Size and location
• Suspected diagnosis
• Depth of the lesion
• Cosmetic considerations
• Need for complete removal
• Possibility of melanoma

Biopsy does not automatically mean that the lesion is cancerous. It is the method used to obtain a reliable diagnosis when examination alone is insufficient.

If cancer is confirmed, additional treatment may depend on the type, depth, margins, location, and pathology findings.

Checking Your Skin Between Visits

Regular self-examination can help patients recognize changes earlier.

Use good lighting and examine:

• Front and back of the body
• Both sides of the arms and legs
• Scalp
• Behind the ears
• Back of the neck
• Palms and soles
• Between toes
• Beneath and around the nails

A mirror, photographs, or help from another person may be useful for areas that are difficult to see. The AAD recommends becoming familiar with existing moles, freckles, and spots so that new or changing lesions are easier to notice.

Sun Protection and Prevention

Screening can identify suspicious changes, but it does not prevent ultraviolet damage.

Preventive habits include:

• Using broad-spectrum sunscreen
• Reapplying during extended outdoor activity
• Seeking shade
• Wearing protective clothing
• Wearing a wide-brimmed hat
• Protecting the ears, neck, hands, and feet
• Avoiding tanning beds
• Avoiding repeated sunburns

Sun protection should continue even after a normal screening result because new lesions can develop later.

Planning Screening During Your Stay in Seoul

International patients should bring:

• Previous biopsy or pathology reports
• Records of past skin cancers
• Photographs showing lesion changes
• A list of medications
• Family history information
• Dates of previous skin examinations
• Details of upcoming travel
• Follow-up options after leaving Korea

Tell the clinic how long you will remain in Seoul. A suspicious lesion may require biopsy, wound care, pathology processing, result review, and additional treatment.

Patients leaving shortly after the appointment should confirm:

• When results will be available
• How results will be communicated
• Whether stitches require removal
• Whether flying or exercise should be restricted
• How medical records can be transferred
• Who will arrange further treatment if necessary

Questions to Ask During Screening

Consider asking:

• Does this lesion need dermoscopy or biopsy?
• Are any other spots concerning?
• Do I need a full-body examination?
• How often should I check my skin?
• Should this lesion be photographed or monitored?
• When will biopsy results be available?
• Will stitches or wound care be required?
• How can follow-up continue after I leave Seoul?

Do Not Wait for a Suspicious Spot to Become Severe

Most moles and skin growths are benign, but visual appearance alone cannot always confirm the diagnosis.

A new or evolving mole, persistent wound, unexplained bleeding lesion, changing nail mark, or growth that looks different from the patient’s other spots should be examined rather than covered with cosmetic treatment.

For patients seeking skin cancer screening in Seoul, a careful full-skin examination, appropriate use of dermoscopy, and reliable biopsy follow-up can help identify concerning lesions while avoiding unnecessary removal of harmless ones.
