4. Varies in Size
Seborrheic keratosis lesions vary in size. Most growths occur on the chest, scalp, face, abdomen, back, and shoulders of affected individuals. Some of them can be so small that people with the condition don’t notice them for months until they gain enough size to be noticeable.
The lesions typically remain small, but if left untreated, they may grow as large as 1-inch across. Larger growths are usually more challenging for medical professionals to remove and may require multiple treatment sessions if using a removal technique such as cryotherapy or electro-surgery to remove the lesions.
Size is not an indication of malignant growth. As discussed, seborrheic keratosis is not cancerous, so you don’t have to concern yourself with metastasis of the lesions into other areas of the body. Visit your doctor for an accurate diagnosis and treatment plan. Your physician will “map” your skin for any signs of other lesions elsewhere on your body.
