Consult your doctor if: You are a woman and develop genital warts, which in rare cases can be associated with cervical cancer
You are older than age 60 and discover what looks like a wart. It may instead be a symptom of a more serious skin condition, such as skin cancer
Warts multiply and spread, causing embarrassment or discomfort
You notice a change in a wart's color or size; this could indicate that the lesion is not a wart but a skin cancer.
