Illustration of a breast cancer cell. The mamma carcinma is a malign tumor of the glandular lobules or lactiferous ducts of the human breast. It's the most common cancer in women.

It's caused by neoplastic cells, e.g. because of mutation of a growth factor, as depicted here (HER2). These proteins are responsible for giving signals to cells to make them divide. A mutation can result in constant signaling, causing the cell to excessively divide, which leads to the feared cancer.
