Since last two decades, researches related to the breast cancer has lead to extraordinary progress in our understanding of the disease, resulting in more efficient and less toxic treatments. Increased public awareness and improved screening have led to earlier diagnosis at stages amenable to complete surgical resection and curative therapies. Consequently, survival rates for breast cancer have improved significantly, particularly in younger women. This article addresses the types, causes, clinical symptoms and various approach both non- drug such as surgery and radiation and drug treatment including chemotherapy, gene therapy etc. Breast cancer is the most common cause of cancer in women and the second most common cause of cancer death in women in the U. Breast cancer refers to cancers originating from breast tissue, most commonly from the inner lining of milk ducts or the lobules that supply the ducts with milk. Worldwide, breast cancer comprises Breast cancer is about times more common in women than in men, although males tend to have poorer outcomes due to delays in diagnosis. Cancer cells are very similar to cells of the organism from which they originated and have similar but not identical DNA and RNA. This is the eeason why they are not very often detected by thz immunz system, in particular, if it is weakened[ 1 ]. All thzse can produce mutations that may start cancer. The rate of DNA and RNA mutations can be too high under some conditions such as; unhealthy emironment due to radiation, chemicals, etc. In cancerous cells, thz process of cell division is disrupted and unregulated, resulting in cell proliferation and tumor growth. The normal cell cycle is as represented in figure 1. Usually, cancer is named after the body part in which it originated; thus, breast cancer refers to the erratic growth and proliferation of cells that originate in the breast tissue[ 9 ]. The breast is composed of two main types of tissues i. Glandular tissues house the milk-producing glands lobules and the ducts the milk passages while stromal tissues include fatty and fibrous connective tissues of the breast. The breast is also made up of lymphatic tissue-immune system tissue that removes cellular fluids and waste[ 10 ]. There are several types of tumors that may develop within different areas of the breast. Most tumors are the result of benign non-cancerous changes within the breast. For example, fibrocystic change is a non-cancerous condition in which women develop cysts accumulated packets of fluid , fibrosis formation of scar-like connective tissue , lumpiness, and areas of thickening, tenderness, or breast pain[ 11 ]. Most breast cancers begin in the cells that line the ducts ductal cancers. Some begin in the cells that line the lobules lobular cancers , while a small number start in the other tissues[ 12 ]. Non-Invasive Breast Cancer cells that are confined to the ducts and do not invade surrounding fatty and connective tissues of the breast. Lobular carcinoma in situ LCIS is less common and considered a marker for increased breast cancer risk. Invasive Breast Cancer cells that break through the duct and lobular wall and invade the surrounding fatty and connective tissues of the breast. Oancer can be invasive without being metastatic spreading to the lymph nodes or other organs[ 13 ]. LCIS is a sharp increase in the number of cells within the milk glands lobules of the breast. For example, ductal comedocarcinoma. ILC is also known as invasive lobular carcinoma. ILC begins in the milk glands lobules of the breast, but often spreads metastatizes to other regions of the body. IDC begins in the milk ducts of the breast and penetrates the wall of the duct, invading the fatty tissue of the breast and possibly other regions of the body. Medullary carcinoma : Medullary carcinoma is an invasive breast cancer that forms a distinct boundary between tumor tissue and normal tissue. Mutinous carcinoma : Also called colloid carcinoma , mutinous carcinoma is a rare breast cancer formed by the mucus-producing cancer cells. Women with mutinous carcinoma generally have a better prognosis than women with more common types of invasive carcinoma. Tubular carcinoma : Tubular carcinomas are a special type of infiltrating invasive breast carcinoma. Women with tubular carcinoma generally have a better prognosis than women with more common types of invasive carcinoma. Phylloides tumors develop in the connective tissues of the breast and may be treated by surgical removal. Phylloides tumors are very rare; less than 10 women die of this type of breast cancer each year in the United States[ 16 , 17 , 18 ]. A woman who has had breast cancer has an increased risk of getting breast cancer in the other breast[ 19 ]. If several members of patient's family have had particular types of cancer, patient may have an increased risk of developing breast cancer[ 19 , 20 ]. Family history has long been known to be a risk factor for breast cancer. Both maternal and paternal relatives are important. The risk is highest if the affected relative developed breast cancer at a young age, had cancer in both breasts, or if she is a close relative. First-degree relatives, mother, sister, daughter are most important in estimating risk. Several second-degree relatives grandmother, aunt with breast cancer may also increase risk. Breast cancer in a male increases the risk for all his close female relatives. Women who have the BRCA1 gene tend to develop breast cancer at an early age[ 21 ]. Alteration in harmonol level may precipitate breast cancer. It could be attended by starting and stopping of periods Menstrual Cycle , Pregnancy in early age, Hormonal replacement therapy, Use of oral pills etc[ 22 ]. Sedentary life style, high dietary intake of fat obesity particularly in postmenopausal women may cause breast cancer.
