Skin Cancer Screening

Skin cancer screening is a medical examination performed to detect skin cancer, including melanoma, basal cell carcinoma, and squamous cell carcinoma, at an early stage.

Purpose

The primary purpose of skin cancer screening is to identify skin cancers before they become symptomatic or cause significant harm. Early detection can improve treatment outcomes and reduce the risk of mortality.

Methods

There are several methods used for skin cancer screening, including:

• Visual examination: A healthcare professional examines the skin from head to toe, looking for any suspicious lesions or moles.
• Dermoscopy: A handheld device with a magnifying lens and light source is used to examine the skin in more detail.
• Biopsy: A sample of tissue is removed from a suspicious lesion for examination under a microscope.

Risk Factors

Certain individuals are at higher risk for developing skin cancer and may benefit from regular screening, including:

• People with fair skin or light hair
• Those with a family history of skin cancer
• Individuals with a history of sunburn or excessive sun exposure
• People with weakened immune systems
• Those with a history of previous skin cancer

Recommendations

The American Cancer Society recommends that adults perform regular self-examinations and consult a healthcare professional if they notice any changes in their skin. The US Preventive Services Task Force (USPSTF) does not recommend routine screening for skin cancer, but suggests that healthcare professionals be aware of the risk factors and perform examinations as part of routine care.

Frequency

The frequency of skin cancer screenings depends on individual risk factors. The American Academy of Dermatology recommends that:

• People at high risk for skin cancer have annual screenings
• Those at moderate risk have biennial screenings
• Low-risk individuals have screenings every 3-5 years

Preparation

To prepare for a skin cancer screening, individuals should:

• Remove any makeup or nail polish
• Avoid wearing tight clothing that may obstruct the examination
• Be prepared to discuss their medical history and risk factors

What to Expect During the Screening

During a skin cancer screening, a healthcare professional will:

• Examine the skin from head to toe, including hard-to-see areas such as the scalp and soles of the feet
• Use dermoscopy to examine suspicious lesions in more detail
• Perform a biopsy if necessary

Follow-Up Care

After a skin cancer screening, individuals may be advised to:

• Return for follow-up examinations at regular intervals
• Undergo further testing or treatment if suspicious lesions are detected
• Practice sun protection and skin self-examination to reduce the risk of developing skin cancer
