Cancer occurs when cells in a certain area of the body begin to divide at a rather rapid pace (cancer.org). Cancer cells grow differently than normal cells. Normally old cells die off and are replaced with new ones. Cancer cells continue to multiply forming more and more abnormal cells (cancer.org). Cancer cells are also capable of invading other tissues whereas normal cells can not (cancer.org). Breast cancer gets its name from the fact that it is a malignant tumor which originates in the cells of the breast (cancer.org). “A malignant tumor is a group of cancer cells that can grow into (invade) surrounding tissues or spread (metastasize) to distant areas of the body” (cancer.org).Breast cancer is one of the most common cancers among women (health.ny.gov). Although this disease occurs mostly in women, it is also possible for men to develop the disease (cancer.org). Before one can understand the types of breast cancer and how they get their names you need to know about the basic structure of a normal breast (cancer.org). A female's breast consists of three main parts: lobules, which are the milk producing glands, ducts, the small tubes that transport the milk from the lobules to the nipples, and stroma, which is the connective and fatty tissue that surround the ducts and lobules (cancer.org).Most forms of breast cancer originate in the cells which line the ducts (cancer.org). I is far less common for breast cancers to begin in the lobules, and hardly any forms begin in the tissues (cancer.org). The lymphatic system is one of the main transporters for breast cancer that is trying to spread to other areas of the body. Most of the lymphatic vessels in the breast are connected to those that lie in the under arm area (cancer.org). If it is found to be true that the cancer cells lymph nodes, then the chances of it having entered the bloodstream and travelled throughout the body are extremely high. There are three main types of breast cancer. These include ductal carcinoma in situ (DCIS), invasive ductal carcinoma (IDC), and invasive lobular carcinoma (ILC). DCIS is the most common type of non-invasive breast cancer (cancer.org). In this form, the cancer cells are found in the ducts, but they have not reached the outlying breast tissue. “About 1 in 5 new breast cancer cases will be DCIS” (cancer.org). IDC is the most common type of breast cancer (cancer.org). This form begins in one of the milk ducts and then spreads to the fatty breast tissue (cancer.org). “About 8 of 10 invasive breast cancers are IDC” (cancer.org). ILC starts in the lobules of the breast and then spreads throughout the body. “About 1 in 10 invasive breast cancers is ILC” (cancer.org). There is no actual known “cause” for breast cancer other than the fact that all forms are due to some sort of genetic mutation in the DNA. However there are numerous risk factors involved in the development of breast cancer. Many of these risk factors are things that can not be changed including gender, age, family history, race, previous chest radiation, and genetics (cancer.org). The non-alterable risk factor that currently has the most scientific research attached to it would be genetic risk factors. Only about 5 to 10% of cancers, including breast, are caused by a genetic mutation that was inherited from one's mother or father (breastcancer.org). The most common inherited gene mutation that has been linked directly to breast cancer is that of the BRCA1 and BRCA2 genes (cancer.org). These genes typically assist in the prevention of cancers by creating proteins which keep abnormal cells from forming (cancer.org). Anyone who has these inherited a mutation of the BRCA1 or BRCA2 genes from either of their parents has a very high risk of developing breast cancer in his or her lifetime. Early detection is definitely the key to treating and surviving breast cancer. The best ways to catch breast cancer early on are by receiving annual...
