Yes, it is possible for skin cancer to look like seborrheic keratosis. Seborrheic keratosis is a type of noncancerous skin growth that can appear anywhere on the body, but is most commonly found on the face, chest, and back. Skin cancer, on the other hand, begins in the outer layer of the skin and can spread to other parts of the body if not treated early. Skin cancer can appear as an abnormal growth on the skin that may resemble seborrheic keratosis, making it difficult to distinguish between the two.
Diagnosis
It is important to have any suspicious skin growths examined by a healthcare professional to determine if it is cancerous or not. During the physical examination, the healthcare professional will look for any signs of skin cancer, such as asymmetry, border irregularity, color changes, or an increase in size. A biopsy may also be performed to take a sample of the skin for further testing.
Treatment
If skin cancer is diagnosed, it is important to seek treatment as soon as possible to prevent it from spreading. Treatment for skin cancer may include surgical removal, topical medications, radiation therapy, or chemotherapy. Seborrheic keratosis, on the other hand, does not require treatment unless a person wishes to have them removed for aesthetic reasons.
