Patient's question:
NoDoctor's answer:
Accessory breast is an extra breast, usually occurring in the area in front of the armpit or under the armpit. Accessory breast generally has no significant impact on the body, and about 0.1% of people may develop breast cancer in it. Due to its different location from the normal breast, it is sometimes easily overlooked. Therefore, when the accessory breast enlarges, there is a lump, or it is suspected to be a tumor, it is necessary to seek medical attention.
