Black Mole on Anus: Causes and Concerns

Hello,

Thank you for reaching out to Dr. Galen. Please find the below response to your query.

While moles are often harmless, changes in size, color, or shape can sometimes indicate a more serious issue, including skin cancer. Anorectal melanoma is a rare cancer that originates in the anus or rectum (the back passage). There's no need to worry, but a complete medical history is necessary. Don't hesitate to schedule an appointment with your doctor as soon as possible to get a proper evaluation. It's better to address any concerns early on for peace of mind and proper medical care.

Thanks & Regards
