Breast Cancer

Introduction

Breast cancer is the uncontrolled growth of cells in the tissue malignant breast. The main risk factors for breast cancer include older age, the first menstruation at an early age, older age at the time of first birth or never having given birth, family history of breast cancer, the fact of using hormones such as estrogen and progesterone, consuming liquor, and of whites. Between 5 to 10% of cases, breast cancer is caused by inherited gene mutations. Of all breast carcinomas, less than 1% occur in males. The breast consists of a set of glands and adipose tissue and is placed between the skin and the chest wall. In reality, not only is a gland, but a set of glandular structures, called lobules, joined together to form a lobe. In a breast there are 15 to 20 lobes. The milk comes from the lobules to the nipple through tiny tubes called ducts (or lactiferous).

Discussion

Breast cancer is a potentially serious disease if not detected and treated early. It is due to the uncontrolled proliferation of certain cells of the mammary gland cells that become malignant. This means that have the ability to break away from the tissue which has generated them to invade surrounding tissues and, in time, also the other organs of the body (Hirshaut & Pressman, 2008; Hunt, 2008). In theory it can form tumors from all types of breast tissue, but the most frequently arise from the glandular cells (from lobules), or from those that form the wall of the ducts. There are several risk factors for breast cancer, some of which are preventable. More than 80 percent of cases of breast cancer affects women over 50 years (Lacroix, 2011; Hirshaut & Pressman, 2008). Familiarity with about 10 percent of women with breast cancer has more ...
