A Case Study on Breast CancerBY: Ritu Choudhary | Category: Breast Cancer | Submitted: 2010-07-08 19:37:22
What is breast cancer The breast is composed of a set of glands and fatty tissue and is placed between the skin and chest wall. Actually not a single gland, but a series 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 dairy). 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 that are transformed into malignant cells. This means having the ability to detach from the fabric to invade the surrounding tissues and, in time, the other organs of the body. In theory it can form tumors from all types of breast tissue, but most frequently tumor arise from the glandular cells (from lobules) or those that form the walls of the ducts. How widespread is breast cancer Breast cancer affects one in 10 women across the world. It is the most common tumor in women and accounts for 25 percent of all cancers affecting women. It is the leading cause of cancer mortality in women, with a mortality rate of 17 percent of all deaths due to cancer. Who is at related risk associated with breast cancer Many women aged between 30 and 50 years are showing signs of mammary dysplasia (alteration of benign breast tissue that has nothing to do with cancer) but may raise some concern at the time of diagnosis. There are different forms of dysplasia, the most common of which is fibrocystic disease. Fibrocystic dysplasia in small cysts, most frequently between 30 and 40 years, these cysts are small fluid-filled, most evident during the premenstrual period. There can be pain. Dysplasia in large cysts, more common in women between 40 and 50 years, we observe the presence of one or more large cysts form rounded, containing liquid. The most common among benign tumor is fibroadenoma, which appears mainly between 25 and 30 years. It appears as a single lump, hard and very mobile, usually painful. The symptoms that accompany the dysplasias and fibroadenomas are: • tightness in your breast; • Breast pain; • nodules that women can "feel" with their hand. There are several risk factors for breast cancer, some of which are preventable. Age: over 80 percent of cases of breast cancer affects women over 50 years. Familiarity with approximately 10 percent of women with breast cancer has more than one close family member ill. There are also some genes that predispose to this type of tumor are the BRCA1 and BRCA2. Mutations in these genes are responsible for 50 per cent of hereditary breast and ovarian cancer. Hormones: several studies have shown that excessive use of estrogen (female hormones for Excellence) facilitates the occurrence of breast cancer. So all the factors that increase their presence have a negative effect and vice versa (eg, pregnancies, which reduce estrogen production by the body, have a protective effect). Types of breast cancer There are two types of breast cancer: the non-invasive and invasive forms. The non-invasive forms are of two types: Ductal carcinoma in situ (DCIS or) is an early form of breast cancer confined to the cells that form the walls of the ducts. If untreated it can become invasive cancer. Lobular carcinoma in situ (LCIS): Although this type of tumor is not invasive, is a sign of increased risk of forming tumors in both breasts. The invasive forms are of two types: Infiltrating ductal carcinoma: it is called so when it exceeds the wall of the duct. Represents between 70 and 80 percent of all cancers of the breast among women. Infiltrating lobular carcinoma: is called so when the tumor beyond the wall of the lobule. Represents 10-15 percent of all cancers of the breast. Can affect both breasts simultaneously or appear in multiple places in the same breast.
