Study Notes
Anatomy of the Breast
- The breast is a glandular organ located on the chest wall, composed of:
- Adipose tissue (fat)
- Glandular tissue (lobes and ducts)
- Fibrous connective tissue
- The breast is divided into four quadrants:
- Upper outer quadrant
- Upper inner quadrant
- Lower outer quadrant
- Lower inner quadrant
Breast Structure
- The breast is made up of 15-20 lobes, each containing:
- Lobules (milk-producing glands)
- Ducts (tubes that carry milk to the nipple)
- The nipple is the pigmented projection in the center of the areola, surrounded by Montgomery's glands
- The areola is the pigmented area surrounding the nipple
Functions of the Breast
- Lactation (milk production) during pregnancy and breastfeeding
- Hormone regulation (estrogen and progesterone)
Breast Development
- Breast development occurs in stages:
- Embryonic development (6-8 weeks gestation)
- Childhood development (puberty)
- Adult development (pregnancy and lactation)
Breast Health
- Breast cancer risk factors:
- Family history
- Genetics
- Hormone levels
- Age
- Breast cancer screening methods:
- Mammography
- Clinical breast exam
- Self-breast exam
Breastfeeding
- Breast milk provides:
- Nutrition
- Immune system development
- Bonding between mother and child
- Breastfeeding benefits:
- Lower risk of breast and ovarian cancer
- Lower risk of type 2 diabetes
- Improved cognitive development
Anatomy of the Breast
- Breast is composed of adipose tissue, glandular tissue, and fibrous connective tissue
- Breast is divided into four quadrants: upper outer, upper inner, lower outer, and lower inner
Breast Structure
- Breast consists of 15-20 lobes
- Each lobe contains lobules (milk-producing glands) and ducts (tubes that carry milk to the nipple)
- Nipple is a pigmented projection in the center of the areola, surrounded by Montgomery's glands
- Areola is the pigmented area surrounding the nipple
Functions of the Breast
- Lactation (milk production) occurs during pregnancy and breastfeeding
- Breast regulates hormones, including estrogen and progesterone
Breast Development
- Breast development occurs in three stages: embryonic development, childhood development, and adult development
- Embryonic development occurs at 6-8 weeks gestation
- Childhood development occurs during puberty
- Adult development occurs during pregnancy and lactation
Breast Health
- Breast cancer risk factors include family history, genetics, hormone levels, and age
- Breast cancer screening methods include mammography, clinical breast exam, and self-breast exam
Breastfeeding
- Breast milk provides nutrition, immune system development, and bonding between mother and child
- Breastfeeding benefits include lower risk of breast and ovarian cancer, lower risk of type 2 diabetes, and improved cognitive development
