Q

what causes Peau d’orange

A

blocked lymphatic drainage from the affected skin area causes superficial oedema which makes the skin thickened. The sweat ducts cause small dimples within the oedematous skin leading to a thickened and dimpled appearance

Q

what is the basic anatomy of the breast

A

the breast sits in front of the chest wall. Most of the breast is adipose tissue, the areola surrounds the nipple. Behind the nipple are the ducts which lead into lobules where breast milk is produced. Milk is secreted through the ducts and out of openings in the nipple
