Out of every 1,000 American males, one will develop breast cancer. According to the American Cancer Society, there are five major types of breast cancer found in men: infiltrating (invasive) ductal carcinoma, ductal carcinoma in situ (early,...
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...
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 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 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 cancer is cancer that starts in the tissues of the breast, most commonly the ducts or lobules, according to the American Cancer Society.
Many people may consider the typical breast cancer symptom to be a lump in the breast, detected during a breast self-examination, clinical breast exam or mammogram. Although a distinct breast lump can indicate the presence of some forms of breast...
Breast cancer is most commonly diagnosed in the ducts and the lobules, according to the National Cancer Institute. These are the tubes and glands that produce and transport breast milk.
Though breast cancer and tumors are principally thought of as affecting women, these conditions can also affect men, although men account for less than 1 percent of breast cancer cases in the United States. Tumors of the breast may be benign,...
The breasts are hormonally regulated organs made up of a range of tissue types: lobules, which make and secrete milk; ducts, which carry the milk from the lobules to the nipple; fat and connective tissue, which support the shape of the breast;...
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...
Each breast contains tissue rich in nerve endings, each of which send feedback to the brain in response to changes in temperature, pain or touch. Tingling in the breast can occur when nerves in the breast become damaged, leading to a "pins and...
According to the American Cancer Society, 1 in 8 women will be diagnosed with breast cancer in her lifetime. It is one of the most commonly diagnosed cancers in women, but death rates from breast cancer have been declining since the 1990s, and new...
According to the American Society of Clinic Oncology, men claim less than 1 percent of all breast cancer cases. In fact, male breast cancer and female breast cancer are very similar. The cancer can affect the different structures of the breast...
Any red bumps that appear on your upper torso also can appear on your breasts. Many times these bumps are a common occurrence and some bumps don't even need treatment. A few types of red bumps on the breasts, however, can indicate a serious...
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...
Each breast contains specialized tissues that facilitate breast milk production and lactation. Milk is produced in bulb-like cellular structures within the breast lobules, then travels along the ducts to the nipple, where it is expelled from the...
After a diagnosis of breast cancer is made, the next step is staging the disease. Staging is a standardized way of describing the extent and spread of the cancer, and helps to guide treatment and prognosis. The tumor size, lymph node involvement,...
Breast cancer develops from cells in breast tissue that change over time. Early detection of breast changes by mammography or a manual exam are key to successful treatment of breast cancer. It is important to understand the types of breast tumors...
Tumors of the breast originate from normal cells within breast tissue that transform into cancerous cells. Once these changes occur, cancerous cells undergo rapid, uncontrollable growth and form a solid tumor, which can invade the breast and other...
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...
Breast tumors can occur within the glandular tissue of the breast, leading to abnormal cell growth that disrupts the normal structure of the breast. Tumors may be non-cancerous or malignant, solid or filled with fluid, occur alone or as groups of...
Ductal carcinoma in-situ is a non-invasive type of breast cancer limited to the milk ducts of the breast. Doctors detect these tumors during routine mammograms. Since this type of tumor doesn't extend beyond the milk ducts, it is highly curable....
The breasts respond to hormones and growth factors from the body, to undergo cycles of proliferation and development throughout a woman's life. Each breast contains a series of milk-producing lobules, connected to the nipple by a series of tubes...
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...
The Mayo Clinic says that nipple discharge refers to fluid that is emitted from the breasts of women who are not breastfeeding. It states that the nipple discharge can be bloody, milky, yellow or green in color. Sometimes, bloody nipple discharge...
Breast cancer development involves the abnormal proliferation of breast tissue cells. As the cancer progresses, cells within the tumor gain invasive properties and begin to migrate into other tissues, eventually travelling to distant sites...
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...
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...
