For many women, breast cancer is a dreaded diagnosis. One in eight women will be diagnosed with this disease, according to the National Institutes of Health. Breast cancer can be categorized into different types: type 1 is early in the cancer...
Breast cancer afflicts mainly women, and when caught early, it is treatable. However, once breast cancer progresses past type 1, treatment gets harder. Type 4 breast cancer is the most advanced form. By the time the cancer has advanced to type 4,...
Merck Manuals, an online medical library, reports that 213,000 women were diagnosed with breast cancer in the United States in 2006. Breast cancer is the second most common type of cancer, and the second leading cause of death due to cancer. There...
According to the American Cancer Society, breast cancer is the most common cancer diagnosis in women other than skin cancer. The breast is composed of various different tissue components, resulting in a variety of potential histopathological types...
When a woman receives a breast cancer diagnosis, a variety of treatment options are available to her. Surgery is typically the first treatment doctors turn to, and many types of surgery exist. The type of surgery the doctor performs depends on the...
Breast cancer is a malignant tumor that usually forms in the milk ducts, or in the milk-producing glands of the breast. It is almost exclusively found in women, but men can get breast cancer, too. Breast cancer is the second leading cause of death...
Breast cancer originates from abnormal, cancer-prone cells that develop in the breast tissue as a result of environmental, genetic and still unknown factors. Over time, cancerous cells proliferate in specific tissues of the breast and form a solid...
According to the Centers for Disease Control and Prevention, breast cancer is the most common cancer in women in the United States and the second most common cause of death from cancer after lung cancer. Though much less common than in women, it...
Breast cancer stems from a mutation of normal breast cells that allows the cells to evade cell death and proliferate uncontrollably, giving rise to unlimited cancer cells. There are several types of breast cancer, which originate in different...
Each breast contains glandular tissue: lobules, which contain cells that produce breast milk; and ducts that carry that milk to the nipple. The nipple itself also contains a small amount of ductal glandular tissue, as well as muscle cells, nerves...
The breasts undergo periods of tightly regulated growth and development throughout puberty and pregnancy. When cells within the breast become mutated, leading to dysregulation of cell growth, this causes uncontrolled cell proliferation, and breast...
Breast cancer is classified according to where the cancer originates. The Mayo Clinic explains that breast cancer can start in the ducts of the breast, the milk-producing lobules of the breast or, sometimes, the connective tissue that is in...
Doctors tell nearly 80 percent of breast-cancer patients that they have ductal carcinoma. This is how pathologists categorize cancers that arise in the milk ducts in breast tissue. Pathologists further classify ductal carcinomas into a dozen...
Breast cancer affects men and women, though it occurs in women much more often. According to the National Cancer Institute, approximately 1 percent of all breast cancers occur in men, who are mostly in their 60s and 70s. According to the Mayo...
Breast tissue consists of fat and connective tissue, blood vessels and lymph nodes. The breast has a branched morphology made up of specialized cell types. The lobules consist of highly arranged rings of cells, which make and secrete milk, which...
Breast cancer refers to a number of cancers that develop from the various cell types of the breast. According to the National Cancer Institute, there were 194,280 cases of breast cancer diagnosed in the United States in 2009, with 192,370 of those...
A breast cancer patient will typically have a team of specialized doctors. Some members of the medical team will be part of the patient's medical care on a recurring basis. Others doctors on the team are part of the breast cancer treatment process...
Breast cancer occurs when one type of cell in breast tissue transforms from a normal cell into a cancerous cell. Every year, 192,000 woman and 2,000 men are diagnosed with breast cancer in the U.S., according to the National Cancer Institute. Just...
Breast cancer is a tumor that develops from any of the cell types within the breast. There are several types of breast cancer that differ in their originating cell type, invasiveness and aggressiveness. Breast-cancer screening is a preventive...
Breast cancer is caused by the development of tumors in breast tissue. There are several different types of breast cancer, classified according to whether tumors begin in the lining, milk gland or connective tissue of the breast, and whether they...
Breast cancer involves the transformation of breast tissue cells into cells that grow uncontrollably. Breast cancer cells can absorb available nutrients resulting in the death of normal tissue, and can metastasize, meaning they spread to other...
Cancer cells are rapidly growing cells that multiply uncontrollably to form tumors. Cancer cells do not know when to stop dividing and don't have the capability to correct errors as easily as regular cells. Chemotherapy keys on these weaknesses to...
Breast cancer occurs when normal cells in breast tissue undergo changes that cause them grow out of control and become solid tumors. The majority of breast cancers originate from cells that line the milk ducts of the breast, but a number of other...
The breasts are hormonally-responsive organs that support lactation and breastfeeding after pregnancy. Breast development involves a number of carefully choreographed cycles of breast cell growth and maturation, which are governed by a number of...
Once a patient is diagnosed with breast cancer, she will typically discuss a treatment plan with her physician. An individual's treatment plan for breast cancer depends on multiple factors. The physician will likely consider tumor size, the type...
Breast cancer develops from mutated cells within the breast that divide uncontrollably to form a tumor. The type of breast cancer is determined by the cell type the cancer originated from and the invasiveness of the tumor. A number of surgical...
Breast cancer is the result of cells in the breast developing genetic abnormalities, which causes them to grow abnormally quickly and spread to other tissues. Not all kinds of breast cancer are the same, however; the prognosis for aggressively...
Breast cancer is one of the most common cancers among women in the United States, according to the American Cancer Society. It is the second leading cause of cancer deaths in women. Breast cancer can be placed in two categories: invasive and...
According to the National Human Genome Research Institute, "genetic testing" covers a wide variety of clinical and non-clinical tests and includes testing of DNA, RNA, and proteins. Breast cancer genetic tests use blood samples or tissue samples...
Following a mastectomy, many women choose to have breast reconstruction surgery. This surgery attempts to restore breast to a normal shape, appearance, and size. Learn about the process of breast reconstruction surgery in this video from a...
