Breast cancer is second only to lung cancer as a cause of cancer deaths in American women One out of every seven women will be diagnosed with breast cancer in 2007 Fortunately, radical mastectomy (surgical removal) is rarely needed today with better treatment options
3. Breast Cancer
Every three minutes, a woman in the United States is diagnosed with breast cancer.
Every twelve minutes a woman dies from breast cancer.
This year, approximately 182,800 women in the United States will be diagnosed with invasive breast cancer. Approximately 40,800 women will die from breast cancer.
No one dies of cancer in the breast, only of cancer that has spread to other parts of the body.
4. Outline
Female Breast Anatomy
Breast Cancer Mammography
Computer-Aided Diagnosis of Breast Cancer
5. Female Breast Anatomy
Breasts consist mainly of fatty tissue interspersed with connective tissue There are also less conspicuous parts lobes ducts lymph nodes
6. Breast Gland
Each breast has 15 to 20 sections (lobes) arranged like the petals of daisy Inside each lobe are many smaller structures called lobules At the end of each lobule are tiny sacs (bulbs) that can produce milk
7. Blood Vessels
Oxygen, nutrients, and other life-sustaining nourishment are delivered to breast tissue by the blood in the arteries and capillaries.
8. Lymphatic System
Lymph ducts: Drain fluid that carries white blood cells (that fight disease) from the breast tissues into lymph nodes under the armpit and behind the breastbone Lymph nodes: Filter harmful bacteria and play a key role in fighting off infection
9. Noncancerous Conditions (1)
Fibrocystic changes: Lumpiness, thickening and swelling, often associated with a woman’s period Cysts: Fluid-filled lumps can range from very tiny to about the size of an egg Fibroadenomas: A solid, round, rubbery lump that moves under skin when touched, occuring most in young women Infections: The breast will likely be red, warm, tender and lumpy Trauma: a blow to the breast or a bruise can cause a lump
