The breasts

The breasts
Average rating: 4 out of 5 star rating

Breast tissue is attached to muscle on the chest wall. A 'tail' of breast tissue extends up into the armpit. Men have a small amount of breast tissue around the nipples. The breasts contain:

  • Many lobules which are made up of glandular tissue ('milk glands'). They make milk after pregnancy.
  • Ducts. These are channels which take milk from the lobules to the nipple.
  • Fatty tissue and supporting connective tissue.
  • Blood vessels, lymph channels and nerves (like all other areas of the body).

Many women find that their breasts become more lumpy and tender before periods. Breasts also alter their size and shape with increasing age, pregnancy, and with marked weight changes. What is important is that you get to know your own breasts - how they look and feel - and report any changes promptly to a doctor.
