While seborrheic keratoses can sometimes resemble skin cancers, such as melanoma, there are key differences. Seborrheic keratoses have a uniform color and shape, which is less common in cancerous growths. Melanomas, for instance, often have irregular borders, multiple colors, and asymmetry. However, any change in the appearance of a skin growth should be evaluated by a healthcare professional to rule out malignancy.

4. Why Your Grandpa’s Age And Skin Type Matter

Seborrheic keratosis is more common in older adults, typically appearing after age 50. This prevalence is likely due to cumulative sun exposure and the natural aging process of the skin. Additionally, individuals with fairer skin types may notice these growths more readily, although they can occur in any skin type. Understanding that these growths are a part of the aging process can help in managing expectations and reducing anxiety associated with their appearance.
