London, Dec 8 (IANS) If a scar on Christina Aguilera’s armpit is anything to go by, there are chances that the singer might have resorted to plastic surgery for breast augmentation.

A scar was visible under her arm when the star waved to fans at a press conference in Tokyo for her new film ‘Burlesque’, reports dailymail.co.uk.

There is a possibility that the scar, in the shape of a small line, is a result of a transaxillary endoscopic breast augmentation, a breast enlargement technique where implants are placed through an armpit incision.

According to experts, the procedure usually leaves an inch-long scar. It is preferred by patients who like to avoid scars on the breast.
