May is Melanoma Awareness Month. Did you know that having a family member with melanoma can increase your own risk of developing this aggressive form of skin cancer?
According to the American Cancer Society, around 10% of melanoma cases affect people with a family history of the condition. If you have close relatives diagnosed with melanoma, understanding the genetic factors involved can help you take proactive steps to protect your skin.
At Florida Westcoast Skin and Cancer Center, board-certified dermatologists Dr. Michael A. Scannon and Dr. Stefanie Altmann provide expert care in identifying and managing melanoma and other skin disorders.
Genetics and Melanoma
Melanoma is the most severe type of skin cancer. It occurs when the pigment-producing cells (melanocytes) undergo DNA damage.
Excessive sun exposure and UV radiation are primary causes. However, genetics also play a crucial role.
Key genetic factors include:
- CDKN2A Gene Mutation: Mutations in this gene can disrupt the body’s ability to suppress tumor growth. This makes individuals more susceptible to melanoma.
- MC1R Gene Variants: Variations in this gene are often associated with fair skin and red hair. They can increase your likelihood of developing melanoma.
- BRCA2 Gene Mutation: Known for its connection to breast and ovarian cancers, mutations in this gene may also elevate the chances of a melanoma diagnosis.
Family history is also a significant melanoma risk factor. This is especially true when:
- Multiple relatives have been diagnosed with melanoma
- Melanoma occurs at a younger age
Prevention for High-Risk Individuals
Protecting your skin and maintaining regular screenings are essential if you have relatives with melanoma. Here are some preventive steps you can take:
- Schedule Regular Skin Exams: Annual skin checks by a dermatologist can help detect melanoma at an early stage.
- Reduce Sun Exposure:
- Use broad-spectrum sunscreen (SPF 30 or higher).
- Wear protective clothing, hats, and sunglasses.
- Avoid indoor tanning beds and spending excessive time in the sun.
- Consider Genetic Testing: Genetic counseling can identify inherited mutations and provide personalized recommendations.
