Hello, Welcome to HealthcareMagic!
As your symptoms suggest, probably you have an accessory nipple/areola; was it since birth? This is not a rare condition & may cause symptoms of itching, suggesting a fungal infection
or eczema. Your age is not for a breast cancer
. Still, for a final & firm diagnosis, I suggest that you consult a General Surgeon
. You may or may not require a biopsy
. You may also get it removed for cosmetic reasons. Wishing you best of health.
