Causes of Luminal Breast Cancer
Scientists find out that breast cancer happens when some cells in this part start to multiply abnormally and uncontrollably. These cancerous cells grow more quickly than healthy cells and build up over time to form a tumor or lump. If left untreated, they may spread through the breast to other parts of the body. This form of cancer tends to begin in the ducts that produce milk or lobules within the breast. Certain studies have identified some environmental, lifestyle, and hormonal factors that would increase the risk of developing breast cancer. However, it is still not fully understood why some people may be at risk, while others may be not. [5]
