Final answer:
Seborrheic keratosis can be treated with cryosurgery, electrocautery, or excision. Treatment like Moh's surgery and 5FU is usually not applicable. No treatment is also an option if the keratosis is asymptomatic.
Step-by-step explanation:
The treatment options for seborrheic keratosis include a variety of methods such as cryosurgery (cryo), electrocautery (EDC), and excisional surgery. Specific treatment methods like Moh's surgery and 5-fluorouracil (5FU) are generally not used for seborrheic keratosis because these treatments are targeted more towards skin cancers. Often, seborrheic keratosis does not require treatment unless it becomes irritated or the individual desires removal for cosmetic reasons. In such cases, 'nothing' is also a valid approach when the keratosis is not causing any problems.
