Melanoma, a serious form of skin cancer, is most commonly associated with adults. While uncommon in children, this aggressive type of skin cancer can affect them. Understanding childhood melanoma is crucial for parents and caregivers.
Understanding Childhood Melanoma
Melanoma in children is less frequent than in adults, accounting for a small percentage of all pediatric cancers. Despite its rarity, it is the most common skin cancer diagnosed in children, affecting individuals of all ages, including infants. It arises from melanocytes, the cells responsible for producing skin pigment.
Diagnosing melanoma in children presents unique challenges, as its appearance may differ significantly from typical adult cases. Pediatric melanoma can be mistaken for benign moles or other common skin conditions, leading to potential delays. Unlike adult melanoma, often linked to long-term ultraviolet (UV) light exposure, sun exposure plays a lesser role in very young children.
Identifying Potential Signs
Recognizing the signs of melanoma in children is important, as they do not always align with the “ABCDE” criteria used for adults (Asymmetry, Border irregularity, Color variation, Diameter, Evolving). Childhood melanoma can present differently, making it harder to spot if only adult indicators are considered. Parents should watch for any new or changing spots on their child’s skin.
Lesions that are pink, red, or flesh-colored, rather than dark brown or black, can indicate melanoma in children. These moles or growths might also be firm or raised, contrasting with the often flat appearance in adults. Other indicators include spots that are itchy, bleed, ooze, or resemble an open sore that heals and then reappears. Rapid growth or a noticeable change in a mole’s size, shape, or color should prompt medical evaluation, even if the lesion lacks typical asymmetry or irregular borders.
Key Risk Factors
Several factors can increase a child’s susceptibility to melanoma. Genetic predisposition plays a role, particularly with a family history of melanoma or atypical moles. Certain inherited conditions also elevate this risk.
A child’s natural skin type is a significant factor. Children with fair skin, light hair and eye color, or those who sunburn easily and tan poorly, have a higher risk. Numerous moles, especially large or unusual congenital moles (birthmarks), also increase melanoma likelihood. While sun exposure is less frequently the primary cause in young children, a history of severe sunburns, particularly during childhood, remains a contributing risk. A weakened immune system due to certain medical conditions or medications can also increase risk.
Prevention and Early Action
Protecting children from excessive sun exposure is a primary strategy for reducing skin cancer risk. This includes seeking shade, especially during peak sun hours (10 a.m. to 4 p.m.). Protective clothing, such as long-sleeved shirts, pants, wide-brimmed hats, and UV-protective sunglasses, offers a physical barrier against harmful rays. Sunscreen application is also important; for children six months and older, a broad-spectrum sunscreen with an SPF of 30 or higher should be applied generously to all exposed skin and reapplied every two hours, or more often if swimming or sweating. Infants younger than six months should primarily be protected by shade and clothing, with minimal sunscreen use only when necessary.
Early detection is paramount for successful treatment if a suspicious lesion is found. Parents should regularly check their child’s skin for any new, unusual, or changing moles or spots. If concerning changes are observed, or a new lesion appears that doesn’t resemble other moles, prompt consultation with a pediatrician or dermatologist is advisable. Professional skin exams are recommended, particularly for children with multiple risk factors.
