Yes, it is possible for seborrheic keratoses to grow back after removal. While some treatments may be more effective than others in preventing recurrence, there is no guarantee that seborrheic keratoses will not return.
Seborrheic keratoses are non-cancerous skin growths that typically appear as raised, dark-colored spots, often with a waxy or scaly surface. While seborrheic keratoses are generally harmless, they can be cosmetically unappealing and thus may be treated for aesthetic reasons. Treatment usually involves freezing, burning, or excising the growth.
In some cases, seborrheic keratoses may return after treatment. This is because the growths can be difficult to remove completely, leaving behind some tissue that can re-grow. In addition, some treatments, such as freezing, may not be effective in completely destroying the tissue and thus may not prevent recurrence.
Overall, although there is no guarantee that seborrheic keratoses will not return after removal, there are treatments available that may be effective in preventing recurrence. If you are concerned about recurrence after treatment, it is best to discuss your options with your dermatologist.
