Types Of Breast Tumors

Breast cancer is cancer that starts in the breast cells worldwide, breast cancer is the second most common type of cancer after lung cancer (10.4% of all cancer incidence , both sexes included), and the fifth most common cause of cancer death. Worldwide, breast cancer is by far the most common cancer among women, with an incidence rate more than twice that of colorectal cancer and cancer of the cervix and about three times higher than lung cancer. However, mortality in the world of breast cancer is only 25% higher than that of lung cancer among women. In 2005, breast cancer caused 502,000 deaths worldwide (7% of cancer deaths, almost 1% of all deaths). The number of cases worldwide has significantly increased since the 1970s, a phenomenon partly due to modern life in the Western world.

In most cases, it is unclear causes normal breast cells to become cancerous. Doctors do know that only 5 percent to 10 percent of breast cancers are hereditary. Families who have genetic defects in two genes, the breast cancer gene 1 (BRCA1) or breast cancer gene 2 (BRCA2), have a much higher risk of developing breast cancer and cancer of the ovary. Other inherited mutations - including the gene for ataxia-telangiectasia mutation, the checkpoint of the cell cycle kinase 2 (CHEK-2) gene and p53 tumor suppressor gene - also make it more likely that you will develop breast cancer . If any of these genes is present in your family, you have a 50 percent chance of having the gene.

Inflammatory breast cancer is a type of breast cancer that involves the skin of the chest. This type of cancer accounts for less than 4% of all breast cancers diagnosed annually in the United States. The physical symptoms of inflammatory breast cancer include redness of the skin of the chest and a general swelling of the breast. In some cases, a piece may be present.

Types of Breast Cancer

Tumor grade: If the cancer is an invasive type, the pathologist assigned a grade. The note is based on how closely the cells of the tissue sample resemble normal tissue under the microscope. The classification information, and the cell type, allows your doctor to determine treatment options.

Tubular carcinoma: This rare type of breast cancer gets its name from the appearance of cancer cells under a microscope. Although invasive breast cancer, the outlook is more favorable than for invasive ductal carcinoma or lobular carcinoma.

Metaplastic carcinomas: carcinoma plastic Met represents less than 1 percent of newly diagnosed breast cancers. This lesion tends to remain localized and contains several types of cells that are not usually seen in other forms of breast cancer. Prognosis and treatment is the same as for invasive ductal carcinoma.

Lobular carcinoma in situ is NOT cancer. But it is a sign that the woman who has 6 to 7 times more likely to develop cancer in their lifetime, a woman who has no LCIS: the same risk you would be less if your mother and sister had cancer.

Most pieces be fibrocystic changes. The term "fibrocystic" refers to fibrosis and cysts. Fibrosis is the formation of fibers (or scar) tissue, and cysts are fluid-filled sacs. Fibrocystic breast changes can cause swelling and pain. This often happens just before a deadline is about to begin. Your breasts may feel lumpy and, sometimes, you may notice a discharge clear or slightly cloudy nipple.
