Breast cancer is a type of cancer originates from breast tissue, generally from the inner lining of milk ducts or the lobules that supply the ducts with milk. Cancers originating from lobules are known as lobular carcinomas whereas from ducts are called ductal carcinomas. (Ref: Breast Cancer, National Cancer Institute) Invasive breast cancer is breast cancer that has spread from the point of origin in the breast ducts/lobules to the surrounding normal tissue cells. In exceptional cases, breast cancer can start in at other sites in breast. Breast cancer occurs in both women and men, though male breast cancer is uncommon. Many breast cancers are sensitive to the hormone estrogen. Thus estrogen leads to development of breast cancer tumor…show more content…
In the past, female patients with HER2-positive breast cancer had a more violent disease. They had a higher risk that the disease will recur as compared to the women who didn’t have this type. This may be changing with distinctively targeted treatments against HER2. Breast Cancer Stages: Once the patient has been determined to have a malignant tumor or is gone through the diagnosis of breast cancer, the healthcare professionals will categorize it in staging method to communicate how far the ailment has progressed. 1) STAGE 0 : At stage 0 no obvious symptoms of breast cancer are observed. It is the early stage i.e non-invasive breast cancer, this is termed as Ductal Carcinoma in Situ. (DCIS). The tumor cells though have originated but at this early stage no sign of active cancerous cells originating or spreading around the site of origin in the breast are observed. The cancer detected at this stage doesn’t require chemotherapy or radiation treatment instead lumpectomy is helpful. 2) STAGE 1: At Stage 1 the break through of cancerous cells start and they invade the surrounding normal functioning cells in the breast, where they originated. This is the invasive breast cancer. Stage 1 is further divided into 1A and 1B substages. Stage 1A: is the invasive form of breast cancer in which a 2 centimeter tumor lump is formed. The cancerous cells yet not spread around and the invasion of normal cells by tumor is nil. This
