Diane wanted so much to compile some basic information about Breast Cancer for her site before her death. She was in hopes it might be useful to other women. Unfortunately her health deteriorated rapidly and she never had the time to accomplish this task. After many weeks of research I have attempted to put together what I think she might have wanted to communicate to other women. The information provided here and throughout Diane’s Site should not be used for diagnosing or treating Breast Cancer. If you have or suspect you have Breast Cancer, please consult your health care provider. My Sincere Thanks ... Diane's brother.
What Is Breast Cancer? Breast cancer is a malignant tumor that has developed from cells of the breast. A malignant tumor is a group of cancer cells that may invade surrounding tissues or spread (metastasize) to distant areas of the body. Breast cancer is the most common malignancy in women and the second leading cause of cancer death (exceeded by lung cancer in 1985). The incidence of breast cancer is very low in the twenties and gradually increases and plateaus at the age of forty-five and increases dramatically after fifty. Fifty percent of breast cancer is diagnosed in women over sixty-five indicating the ongoing necessity of yearly screening throughout a woman's life. The disease occurs almost entirely in women, but men can get it, too. For every 100 women with breast cancer, 1 male will develop the disease. The information on this page refers only to Breast Cancer in women. |
The Normal Breast Structure The main parts of the female breast are lobules (milk-producing glands), ducts (milk passages that connect the lobules and the nipple), and stroma (fatty tissue and ligaments surrounding the ducts and lobules, blood vessels, and lymphatic vessels). Most breast cancers begin in the ducts (ductal), some in the lobules (lobular) and the rest in other tissues. |
Lymphatic vessels are like veins, except that they carry lymph instead of blood. Lymph is a clear fluid that contains tissue waste products and immune system cells (cells that are important in fighting infections). Lymph nodes are small bean-shaped collections of immune system cells that are found along lymphatic vessels. Cancer cells may enter lymphatic vessels and spread to lymph nodes. Most lymphatic vessels of the breast lead to axillary (underarm) lymph nodes. Some lymphatic vessels connect to lymph nodes inside the chest (internal mammary nodes) and either above or below the collarbone (supra or infraclavicular nodes). When breast cancer cells reach the axillary (underarm) lymph nodes, they may continue to grow, often causing the lymph nodes in that area to swell. If breast cancer cells have multiplied in the axillary lymph nodes, there is a chance that they may have spread to other parts of the body. Most breast lumps are not cancerous, that is, they are benign. Most lumps turn out to be fibrocystic changes. The term "fibrocystic" refers to fibrosis and cysts. Fibrosis is the formation of fibrous (or scar-like) tissue, and cysts are fluid-filled sacs. Fibrocystic changes can cause breast swelling and pain. This often happens just before a period is about to begin. The breasts may feel nodular, or lumpy, and, sometimes, you may observe a clear or slightly cloudy nipple discharge. Benign breast tumors such as fibroadenomas or papillomas are abnormal growths, but they are not cancer and cannot spread outside of the breast to other organs. |
Symptoms of Breast Cancers
While a history of breast cancer in the family may lead to increased risk, most breast cancers are diagnosed in women with NO family history. Many breast cancers develop with no symptoms at all. Some tumors may be visible on a mammogram before symptoms develop. It is important for all women to be familiar with the appearance, feel, shape, and texture of their breasts in order to detect changes as soon as they occur. Specifically, a woman should look for the following: Warm, red, swollen breasts with a rash resembling the skin of an orange. Skin irritation or changes, such as puckers, dimples, scaliness, or new creases. New lumps (many women normally have lumpy breasts) or a thickening in
the Nipple tenderness, discharge, or physical changes (such as turned inward
nipple or Pain in the breast (usually not a symptom of breast cancer, but should be reported to a doctor). Women who experience any of these changes should contact a doctor immediately. |

What is the Prognosis for Breast Cancer? Most women who are treated for early breast cancer go on to lie healthy, active lives. You may have more choices of treatment if your breast cancer is found early. Treatments have changed over time. Today, many women who are diagnosed with breast cancer do not have to lose a breast. Because there are improved ways to treat breast cancer, it is more important than ever for you to learn all you can. Working with your team of medical specialists, you can play a key role in choosing the treatment that is best for you. Once your doctor has determined your specific type and stage of breast cancer, you can begin to plan for your treatment and recovery. Your chance of recovery will depend on many factors, including: The type and stage of your cancer (what kind of cancer; the size of the tumor; and whether it is only in your breast, or has spread to any lymph nodes or to other parts of your body). How fast the cancer is growing. Special tests on the tissue can measure how fast the cancer cells are dividing and how different they are compared to normal breast cells. How much the breast cancer cells depend on female hormones (estrogen and progesterone) for growth which can be measured by hormone receptor tests. Patients whose tumors are found to be dependent on hormones (described as estrogen-positive or progesterone positive) can be treated hormonal therapy to prevent further growth or recurrence of breast cancer.
