What Is a Breast Cancer Lump?
A breast cancer lump is a group of cancerous cells that develop when abnormal cells grow uncontrollably in an area of the breast. Over time, this mass may become bigger in size and spread to surrounding tissues. These cells may eventually move to other parts of the body through the lymphatic system or bloodstream. This is also known as metastasis. Read the next sections to learn more information about breast cancer lumps. [1]
