A new study challenges the belief that melanoma risk is primarily related to sun exposure.

Researchers found that up to 15% of patients with melanoma had mutations in cancer susceptibility genes.

This indicates a hereditary component to the disease.

The findings suggest a need for expanded genetic testing for individuals with a family history of melanoma.

The study highlights the importance of considering genetic factors beyond sun exposure in understanding melanoma development and treatment.

Further research is underway to explore the impact of inherited mutations on treatment outcomes and disease severity.
