What is Breast Cancer?
Breast cancer occurs when normal breast Tues switch structure and spread. It infects the tissue and the other near the gland or lobules, blood vessels, lymphatic vessels and lymph nodes. Usually formed because the tumor accumulation of abnormal cells. Each type of tissue in the breast can form cancer but it usually begins in the gland or ducts.
Breast cancer contributed percent for the highest cancer among women. Breast cancer was ranked fifth for mortality due to cancer and is a major contributor as a result of cancer death among women. Throughout the life of a woman with breast cancer risk of 1 in 8 and probably died as a result are 1 in 28.

Classification of Breast Cancer
Breast cancer is classified according to several factors such as other cancers. Factor that is considered normal tissue source, the location of the tumor or tissue source, tissue type or histology, tumor grade, tumor stage, tumor activity and the emergence, spread and status of lymph. For the first cell exchange the structure but in its original location in the basemen membrane ducts or lobule. Mitosis (duplication cell) and metastasis (spread) then occurs through the membrane to move basemen and remote areas in the body.
Signs and Symptoms of Breast Cancer 
Lump formation is a common sign remained for a long period of time. Possible asymptomatic nodule will appear before other signs or symptoms arise. Mastodinia (breast pain) or lump pain on another is a symptom of breast cancer at an early stage. Then signs of inflammation such as pain, heat, redness or swelling will occur if the small lymphatic vessels in the skin and blood lymphatic vessels attacked by abnormal tissue. Skin texture will have orange boy, who is also referred to as “peau d’orange”.
Lump may occur in the breast or the armpit. Breast appearance will also be change to thicken or increase the size and shape. Breast cancer skin may look like or groove forming ridge. Nipple will pulling in, become red or scaly or have abnormal discharge. When it spread to other areas, will reincarnate sign such as fever, cold horror, bone and joint pain, jaundice, neurological symptoms and pleura effuse. Symptoms of breast cancer may not appear, therefore women should take the initiative to make the diagnosis by checking their own breast cancer and underwent tests each year.
Stage Breast Cancer
To diagnose breast cancer, the observation made by mammography or breast MRI. Stage breast cancer is determined by the nature of reproductive cells or level (proliferation).
Stage 0 cancer or tumor in origin (carcinoma in situ) is calculated as the risk of breast cancer without the presence of the disease itself. Lobular carcinoma in situ or LCIS refers to abnormal cells lining the glands in the breast. Ductal carcinoma in situ or DCIS refers to abnormal cells lining the breast ductus.
Stage I refers to breast cancer at an early stage in which the transverse tumor size less than 2 centimeters and has not yet spread. Stage II breast cancer also refers to the level where the tumor size is between 2 to 5 centimeters, or more than 5 centimeters but has not spread, or less than 2 centimeters but has spread to lymph nodes armpit.
Stage III is where the transverse tumor size was increased to 5 centimeters and has spread to the armpit lymph nodes, or has spread to many lymph nodes armpit, or has spread to lymph nodes in the isolated clavicle or sternum.
Stage IV refers to situations in which breast cancer has spread to areas outside the chest area.
Treatment Method
Treatment depends on the characteristics or classes of breast cancer. There are several types of treatment such as chemotherapy, surgery and Homeopathy (and other alternative treatments). Prognosis (prediction) of breast cancer at an early stage is usually good, but at the end, as with other cancers is not good.
