How Dangerous is a Solar Keratosis
Sunspots can become dangerous. Skin cancers called Squamous Cell Carcinoma can develop from sunspots in people who are at risk.
As many as 65% of all primary squamous cell carcinomas arise from previously diagnosed solar keratoses in high-risk individuals.
Solar keratoses are diagnosed clinically based on their characteristics, and in suspicious cases a biopsy may be required to rule out malignancy.
