Overview
Breasts are a pair of organs in the chest that have several important roles. They are made of different tissues that support growth and function during puberty and adulthood.
Key Parts
- Breast tissue: glandular tissue that can produce milk after childbirth.
- Fat tissue: gives the breast its size and shape.
- Milk ducts: channels that carry milk from the glands to the nipple.
- Nipple: the small protrusion where milk exits during breastfeeding (in people who choose to breastfeed).
- Areola: the pigmented area surrounding the nipple.
Development During Puberty
- Ovaries release hormones that stimulate breast development.
- Breasts grow in size and tissue changes from childhood to adolescence.
- There is natural variation in size, shape, and symmetry between individuals.
Functions
The primary function in humans who breastfeed is producing and delivering milk to nourish a baby. Even if someone does not breastfeed, breasts can be a normal part of anatomy and body image.
Care and Health
- Do regular self-checks to notice any unusual changes, such as lumps, skin changes, or pain.
- Wear a properly fitting bra for support and comfort.
- Consult a healthcare provider if you notice anything concerning.
