About Breast Cancer
Every year, more than 180,000 American women are diagnosed with breast cancer. It is the most common cancer in women and the second-most deadly (lung cancer is the most common cause of cancer deaths in women). But in spite of these sobering statistics, there is every reason for hope. In scientific studies, annual screening mammography in women age 40 and older has reduced the death rate from breast cancer. In addition, advanced diagnostic tests and newer, more effective treatment options are making it possible for more and more women to survive this disease.
If you develop breast cancer, you can also play a key role in your outcome — by educating yourself now. It's important for women to understand the disease, the significance of early diagnosis, and all the available treatment options. After all, knowledge is power.
What is Breast Cancer?
Breast cancer is a malignant (cancerous) growth that has developed from cells in one of the tissue structures found in the breast. Breast cancer develops when cells in any part of the breast grow and divide in an uncontrolled fashion. It may be limited to the inside of the ducts or it may grow in a way that invades or damages nearby tissue. These cells may also have the potential to spread and grow in other areas of the body.
Types of Breast Cancer
Infiltrating Ductal Carcinoma
The most common type of breast cancer is called Infiltrating Ductal Carcinoma, which began in the lining of the milk duct and has grown through the wall of the duct into the surrounding tissue. Infiltrating lobular carcinoma, another common form of breast cancer, begins in the lining of the lobules or glands and invades through the wall.
Non-Invasive Breast Cancer (Ductal Carcinoma In Situ)
Ductal Carcinoma in Situ (DCIS) which is a type of non-invasive ductal cancer and inflammatory cance, which is a rapidly progressing type of breast cancer that may sometimes be mistaken for a breast infection.
Lobular Carcinoma In Situ (LCIS)
Despite the name, LCIS is usually considered a marker for the risk of developing breast cancer that does not need local treatment, unless is it Pleomorphic LCIS which is treated more like DCIS.
