Facts About Breast Cancer
Cancer is a disease in which cells in the body grow out of control. When cancer starts in the breast, it is called breast cancer. Except for skin cancer, breast cancer is the most common cancer in American women.
A breast is made up of three main parts: glands, ducts, and connective tissue. The glands produce milk. The ducts are passages that carry milk to the nipple. The connective tissue (which consists of fibrous and fatty tissue) connects and holds everything together.
Lumps in the Breast
Many conditions can cause lumps in the breast, including cancer. But most breast lumps are caused by other medical conditions. The two most common causes of breast lumps are fibrocystic breast condition and cysts. Fibrocystic condition causes noncancerous changes in the breast that can make them lumpy, tender, and sore. Cysts are small fluid-filled sacs that can develop in the breast.
Triple Negative Breast Cancer
One to three percent of invasive breast cancers diagnosed will be Triple Negative Breast Cancer (TNBC). TNBCs tend to occur more often in younger women and in African-American women, and tend to grow and spread more quickly than most other types of breast cancer. This cancer’s cells (usually invasive ductal carcinomas) lack estrogen receptors and progesterone receptors, and do not have an excess of the HER2 protein on their surfaces.
