The breast is mainly made up of lobules ( milk – producing glands ) and ducts ( tubes that carry milk to the nipple). Breast cancer is a disease of cells and starts when the cells in the breast begin to divide and grow in an abnormal way.
Breast cancer starts when cells in the breast begin to divide and grow in an abnormal way. Invasive ductal breast cancer means the cancer cells are no longer only in the breast ducts.
Triple negative breast cancer is a type of breast cancer that does not have any of the three receptors commonly found on breast cancer cells – the oestrogen, progesterone and HER2 receptors. Around 15% of breast cancers are triple negative.
Inflammatory breast cancer (IBC) is a rare and very aggressive disease in which cancer cells block lymph vessels in the skin of the breast. This type of breast cancer is called “inflammatory” because the breast often looks swollen and red, or “inflamed.”
Metastatic breast cancer occurs when breast cancer cells spread to other parts of the body. This usually includes the lungs, liver, bones or brain. This is also referred as advanced breast cancer, secondary cancers or stage IV breast cancer.
