Breast cancer is a malignancy that begins in cells of the breast. This is especially common in women, but did not rule occurs also in men.
Female breast anatomy
Breast cancer is a disease in which malignant cells form in breast tissue. Let's examine the structure of normal breast anatomy.
Breast Anatomy pictureFemale breast consisting of glands that make breast milk (called lobules), ducts that carry milk from the tiny lobules to the nipple (called ducts), strapped him fat and tissue, blood vessels, and lymph nodes. The majority of breast cancer begins in cells lining the ducts (ductal cancer), some begin in the lobules (lobular cancer), and a small portion originated on other networks.

Bening Lymph System
Lymphatic system is one of the main ways to spread of breast cancer. Breast cancer cells can enter lymphatic vessels and begin to grow in the lymph nodes. If breast cancer cells have reached the lymph vessels in the armpit (axilaris node), the sign is swelling of lymph nodes in the armpit. When this happens it is likely that cancer cells also enter the bloodstream and spread to other organs. It can affect cancer treatment options from your doctor.
Breast lump is not cancer
Most lumps that occur in the breast are not cancer. However, few have been studied under a microscope to make sure they are not cancer.
Fibrocystic changes
Most breast lumps turn out to be fibrocystic changes. The term refers to the fibro and fibrocystic cyst. Fibrosis is scar tissue formation, while the cyst is a sac filled with fluid. Fibrocystic changes can cause breast swelling and pain. Often occur before the menstrual period begins. Breasts may feel rubbery and sometimes out of the clear fluid / milk from the nipple.
Types of Breast Cancer
There are many types of breast cancer, but some of them very rare. Sometimes a single breast tumor can be a combination of the following types or a mixture of invasive and in situ cancer.
Ductal carcinoma in situ (DCIS): This is a type of noninvasive breast cancer is most common. DCIS means the cancer cells are inside the ducts and has not spread beyond the walls of the ducts into the surrounding breast tissue.
About 1 in 5 new cases of breast cancer is DCIS. Almost all women with cancer at an early stage is curable. A mammogram is often the best way for early detection of DCIS.
When diagnosed with DCIS, a pathologist will usually find the area of cancer cells that have died, called tumor necrosis in a tissue sample. If necrosis is found, it seems more aggressive tumors. Comedocarsinoma term sometimes used to describe DCIS with necrosis.
Lobular carcinoma in situ (LCIS): Although this is actually not cancer, but LCIS is sometimes classified as a type of noninvasive breast cancer. Starting from the glands that produce milk, but do not develop past the walls of the lobules.
Most cancer experts argue that LCIS itself often does not become invasive cancer, but women with this condition have a higher risk to develop into invasive breast cancer in the breast of the same or different. Therefore, routine mammography is recommended. Invasive (or infiltrating) ductal carcinoma (IDC): This is the most common breast cancer. Starting from the duct, through the duct wall, and develops into the fatty breast tissue. At this point, it may spread (metastasize) to other organs through the lymphatic system and bloodstream. About 8 out of 10 invasive breast cancers are this type. Invasive (infiltrating) lobular carcinoma (ILC): This cancer starts in the lobules. Such as IDC, it can spread (metastasize) to other parts of the body. About 1 in 10 invasive breast cancers are of this type. ILC is more difficult to detect by mammogram than IDC.
The types of Rare Breast Cancer Occurs
Inflamed Breast Cancer (IBC): This type of invasive breast cancer is rare, the statistics are about 1-3% of all breast cancer cases. Usually does not happen a single lump or tumor. Instead, IBC makes the skin breast look red and feel warm. It also makes the skin thick and wrinkled breasts look like orange peel. Doctors usually discover that these changes are not caused by inflammatory / inflammation or infection, but because cancer cells block the lymph vessels have been in the skin. The affected breast is usually bigger, chewy, tender or itchy. In the early stages, this type of cancer is sometimes mistaken as a breast infection (mastitis) and treated with antibiotics. If not improved, a doctor may recommend a biopsy. Because there is not a bump, this type is usually not detected when the mammogram. This type of cancer tends to spread and it looks worse than the type of IBC or ILC.
Paget's disease of the nipple: This type of breast cancer begins in the ducts and spreads to the skin of the nipple and then to the areola (dark circle around the nipple). This type is rare (only about 1% of all breast cancer cases). The sign is the skin of the nipple and areola are cracked, scaly, and red, with the bleed area. Patients usually notice any areas such as burning or itching.
Paget's disease is often associated with DCIS, IDC, or more often. Treatment often requires a mastectomy. If DCIS is found only (no invasive cancer), when the breast is removed, recovery is very good hope.
