1What Is Breast Cancer
Breast cancer occurs when mutations in genes cause breast cells to multiply and divide uncontrollably. In general, these cancerous cells are produced in either the ducts or the lobules of this organ. Ducts are those pathways which transport milk to the nipple, while lobules are those parts which form milk. Also, breast cancer would develop in the fibrous connective or fatty tissue. These uncontrolled cells tend to attack other healthy tissues in your breast and spread to the lymph nodes under your arms.
