Family history of skin cancer or melanoma
Overview
A family history of skin cancer or melanoma refers to having blood relatives who have been diagnosed with these types of skin cancers. This genetic predisposition increases an individual's risk of developing skin cancer compared to those without a family history.
Common Causes
Having relatives with skin cancer or melanoma increases your risk due to shared genetic factors that affect how your skin responds to sun damage. Family members often have similar skin types, such as fair complexion or tendency to burn easily, which can make them more susceptible to developing skin cancers. Additionally, families typically share similar sun exposure habits and lifestyle patterns that may contribute to skin cancer risk over time.
Severity Levels
Mild: One distant relative (like a grandparent or cousin) has had common skin cancer types like basal cell or squamous cell carcinoma. Your risk is slightly elevated but still manageable with regular skin checks.
Moderate: One or more close relatives (parents or siblings) have had skin cancer, or you have multiple family members with any type of skin cancer. This increases your risk significantly and requires more frequent monitoring.
Severe: Multiple close family members have had melanoma, or there's a pattern of aggressive skin cancers in your family. You may carry genetic mutations that substantially increase your risk and need specialized genetic counseling and intensive screening.
Medical Attention
If you have close blood relatives who have had skin cancer or melanoma, it's important to see a dermatologist for regular skin screenings, typically starting earlier and more frequently than standard recommendations. Schedule an appointment if you notice any new, changing, or unusual moles or skin spots. Consider genetic counseling if multiple family members have been affected, and discuss your family history with your primary care doctor to establish an appropriate monitoring plan.
