The breasts

Breasts are made up of fat, supportive (connective) tissue and glandular tissue containing lobes. The lobes (milk glands) are where breast milk is made. They connect to the nipple by a network of fine tubes called milk ducts.

It is common for a woman’s breasts to be a different size or shape from each other. They also feel different at various times of the month. Learning how your breasts look and feel at different times of the month helps you know what is normal for you. We have more information about the kinds of changes to look out for.

The breasts and the lymphatic system

The breast tissue extends into the lower armpit (axilla). The armpits also contain a collection of lymph nodes (glands), which are part of the lymphatic system. The lymphatic system protects you from infection and disease. It is a network of lymph glands throughout the body connected by tiny vessels called lymph vessels.
