N63: Unspecified lump in breast
The breast is made up of fatty tissue, connective tissue and the mammary gland. Milk is produced in the mammary gland during and after pregnancy so that the child can be fed.
One or more parts of your breast may feel firmer than usual. These lumps can have many different causes.
Lumps in the breast may be harmless. Sometimes, lumps in the breast may be an indication of a severe disease.
