Ductal carcinoma in situ (DCIS) is a type of non-invasive breast cancer that, when detected early, has an excellent prognosis. The cancer cells are confined to a duct within the breast and have usually not spread to the surrounding breast tissue...
Ductal carcinoma in situ, also called DCIS, is a relatively mild form of breast cancer, accounting for around 25 percent of breast cancer cases, according to Imaginis.com. The disease is characterized by abnormal cell growth within a breast duct,...
Ductal carcinoma in situ, or DCIS, is the earliest form of breast cancer and is highly treatable, according to the MayoClinic.com. DCIS is a small cancerous growth in a milk duct of the breast that is contained within the duct and has not spread...
A variety of genetic disorders can affect lung structure and function. The severity of these disorders depends on the degree to which lung function is impaired. Hereditary lung diseases such as alpha-1 antitrypsin deficiency, cystic fibrosis,...
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...
Breast cancer occurs when normal cells within the breast transform into tumors that grow uncontrollably. The causes of breast cancer are complex and can result in the formation of a variety of different types of tumors. Contact your doctor if you...
Breast cancer tumors typically originate from normal cells within the breast that undergo genetic and metabolic changes that cause their uncontrolled, rapid growth. The American Cancer Society describes many different 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...
The National Cancer Institute estimates that in 2010, doctors diagnosed breast cancer in 207,090 women and 1,970 men in the United States. This type of cancer starts in the tissue of the breast, and the exact location varies. As the cancer...
According to the American Cancer Society, over 250,000 new breast cancer cases were diagnosed in 2009 in the U.S., in both women and men, with women having the highest prevalence. Breast cancer starts in the breast tissue, and is categorized by...
Pap smears diagnose early changes in the cervix, the lower part of the uterus, that may lead to cervical cancer, a disease that kills approximately 7,500 women each year, according to the Louisiana State University Health System. A painless,...
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...
Non-invasive breast cancer, often called "Stage 0" breast cancer, can be a very early stage in the development of a breast tumor or simply a risk factor for future breast cancer onset. There are two subtypes of non-invasive breast cancer: lobular...
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...
When you're diagnosed with ductal carcinoma in situ, the abnormal cells associated with this disease are confined to the ducts of the breast. And while DCIS is considered a noninvasive form of cancer, there is the potential to have slight...
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 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...
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...
Breast cancer is cancer that starts in the tissues of the breast, most commonly the ducts or lobules, according to the American Cancer Society.
Breast cancer is a malignant form of cells that grow outside the normal cell cycle in the breast. This cancer is the leading form of cancer affecting women (after skin cancers), according to the American Cancer Society, and it is the second...
The breasts have a branching morphology made up of numerous lobules, which connect to the nipple by a series of ducts. Fat cells, lymph nodes and connective tissue surround the lobules and ducts to support and shape the breasts. Each type of...
The skin is made up of a number of specialized cells, including melanocytes---the pigment-producing cells that provide the skin's natural color. Malignant melanoma is an advanced cancer that originates in melanocytes and then spreads to the lymph...
Breasts are made of lobules, glands, ducts and fibrous tissue, all of which are made up of cells that have the potential to form tumors. Tumors can either be benign (not cancer) or malignant (cancer). Though the American Cancer Society reports...
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...
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.
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 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 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...
Breast cancer is cancer that forms in breast tissue. It commonly arises in the ducts or lobules, the tubes and glands in the breast associated with milk production and transport. It can be diagnosed in both men and women, but is mainly diagnosed...
