What Gives the Breast Its Shape?

Frequently Asked Questions: Breast Augmentation & Breast Implants

The breast consists of milk ducts and glands, surrounded by fatty tissue that provides its shape and feel. Situated beneath the breast is the pectoralis major muscle or chest muscle. Factors which may combine to stretch the skin and cause the breast to droop or sag include pregnancy (when milk glands are temporarily enlarged), rapid weight loss, and the effects of gravity as you age.
