What is the difference between senile keratosis and seborrheic keratosis?

Senile keratosis, often referred to as actinic keratosis, is a precancerous skin condition caused by sun exposure, typically presenting as rough, scaly patches. Seborrheic keratosis, on the other hand, is a benign, non-cancerous skin growth that appears as raised, warty lesions and is commonly associated with aging. While both conditions can occur in older adults, they differ in their causes, appearance, and potential for malignancy.
