The breast cancer is a disease in which breast cells begin to grow rapidly in an uncontrolled rate. The breast cancer is the most common cancer in women, while lung cancer remains the most common cause of death in both, men and women. Approximately 1% of all the breast cancers occur in adult men.

Metastatic breast cancer - Metastasis is the movement of the cancer cells, either trough the bloodstream or the lymphatic system. Metastatic breast cancer occurs when the cancer cells move from breast to other parts of the body and continue to grow in the new location. The metastasis near the breast areas, for example in the axilla (under arm), is called regional metastasis. In other areas of the body, such as in bone, liver or lung, is called metastasis from a distance. Metastatic cancer may be present when initial diagnosed or it may occur few months later or even years.

Recurrent breast cancer - Recurrent breast cancer is that type of cancer that recurs after treatment was finished. The breast cancer recurs in 20% to 30% from all cases after the initial diagnosis. Recurrence rate is higher in the first 5 years after treatment, but may occur in up to 30 years after initial diagnosis. The locally recurrent indicate that the disease reappeared in the breast, after tumor excision and radiotherapy, or in the skin of the chest wall, after mastectomy. The local recurrence of the breast cancer is not considered metastases.

The regional recurring significance, usually, as a disease reappeared near lymph nodes, as an example armpit (axillary lymph nodes) or in the neck (lymph nodes and over clavicle). The recurrent distance refers to the breast cancer which appeared in other parts of the body, such as in live, lung, bones or brain.

Causes - The exact cause of breast cancer is not known. The female hormones and the increase in age, play a role. The breast cancer is a common disease in women over 50 years. The probability that a woman will develop breast cancer at the age of 30 years is 1 in 250.  The risk of a woman to develop breast cancer at the age of 40 is 1 in 70. The women with a history of breast cancer have an increased risk of developing recurrent or metastatic breast cancer, most of recurrences appear between 5 to 10 years from the initial diagnosis.

Symptoms - The metastatic or recurrent cancer symptoms depend on the location and stretching. There may be specific physical symptoms, such as a tumor in the breast or chest wall, bone pain or an interrupted breathing (shorted). They also may be no symptoms at all. Sometimes, the recurrent or metastatic cancer is discovered before the symptoms to appear either on a chest x-rays or to laboratory tests which are made for staging or for tracking.

Diagnosis - The metastatic and recurrent breast cancer is diagnosed using physical examination, mammograms, blood tests, chest radiography, bone, ultrasound and CT scan or MRI. The diagnosis of the breast cancer should be confirmed by a biopsy of the suspected region.

The breast cancer is the increase of the abnormal cells which are found (lining) between ducts and breast lobules. The breast cancer is classified according to the microscopic appearance of the cancer cells. Stages indicate how far cancer cells have moved. The doctor who treats breast cancer, determine the stage by picking up the results after tests, as biopsy of lymph nodes, blood tests, bone radiography. The cancer staging is one of the most important factors in choosing the right treatment.
