While often associated with adults, skin cancer can also affect children. Though less common in younger individuals, it represents a serious health concern parents should understand. Melanoma, the most severe form of skin cancer, accounts for up to 3 percent of all pediatric cancers. Children’s skin is particularly susceptible to ultraviolet (UV) radiation, which can increase the likelihood of developing skin cancer later in life. Recognizing the potential for skin cancer in childhood and understanding its signs and prevention methods are important steps for early detection and successful management.
Skin Cancer Types in Children
The most prevalent type of skin cancer in children and adolescents is melanoma. This cancer originates in melanocytes, the skin cells responsible for producing pigment. Melanoma in children can present differently than in adults; it may appear as a new or changing mole and can spread quickly.
Basal cell carcinoma, a common skin cancer in adults, is rare in children unless certain genetic conditions are present, such as basal cell nevus syndrome or xeroderma pigmentosum. This type of cancer progresses slowly and typically appears as a small, shiny bump or nodule on sun-exposed areas like the head, neck, or face. Squamous cell carcinoma is also uncommon in children. While more aggressive than basal cell carcinoma, it is highly treatable and can manifest as nodules or red, scaly patches of skin, often on the face, ears, or lips.
Risk Factors for Childhood Skin Cancer
Several factors can increase a child’s susceptibility to skin cancer. A primary contributor is excessive sun exposure, particularly blistering sunburns experienced during childhood and adolescence, which significantly elevate the risk of melanoma later in life.
Fair skin, with light hair, light eyes, and a tendency to freckle, also increases risk. Children with numerous moles, especially atypical ones, have a higher likelihood of developing melanoma; this risk is elevated for those with over 100 moles or large moles exceeding 5 mm in diameter. A family history of melanoma is another risk factor. Certain rare inherited conditions, like xeroderma pigmentosum, and weakened immune systems, such as in children who have received organ transplants, can also raise the risk of pediatric skin cancer.
Identifying Skin Cancer Warning Signs
Detecting skin cancer early in children relies on careful observation of their skin. Parents should regularly examine their child’s moles and any new skin lesions. Recognizing changes in existing moles is particularly important for early melanoma detection.
Pediatric melanoma often presents as a suspicious mole that changes in shape, color, or size. Unlike adult melanoma, which is often dark, a child’s melanoma might be a single color, including red, pink, or purple, and may not contain black or brown pigment. Other warning signs include a mole that is painful, itchy, bleeds, or appears as a sore that does not heal. A rapidly growing lump or a dark streak under a fingernail or toenail not caused by injury also warrant medical attention. If any of these changes are observed, prompt consultation with a pediatrician or dermatologist is advisable, as early detection supports effective management.
Protecting Children from Skin Cancer
Preventing sun damage during childhood is a crucial strategy for reducing the risk of skin cancer later in life. Limiting a child’s exposure to direct sunlight, especially during peak hours, can yield long-term benefits. Seeking shade, particularly between 10 AM and 4 PM when the sun’s rays are strongest, is a practical approach.
Protective clothing offers an effective barrier against UV radiation. This includes wearing wide-brimmed hats, long-sleeved shirts, and pants made from tightly woven fabrics or those with a UPF (Ultraviolet Protection Factor) rating. Sunglasses that block 100% of UV rays also protect delicate eye tissue.
Applying broad-spectrum sunscreen with an SPF (Sun Protection Factor) of 30 or higher is recommended for all exposed skin. Sunscreen should be applied generously and frequently, especially after swimming or sweating. While light-skinned children require significant protection, children of all skin tones need sun safety, as any tanning or burning can cause skin damage. Avoiding indoor tanning devices entirely is also important, as they significantly increase melanoma risk.
