Overview of breast cancer: is one of the most common malignant tumors of women, according to statistics, morbidity, accounting for 7-10% body a variety of malignancies, second only to cervical cancer in women.

Usually occurs in malignant breast epithelial tissue. Is a serious impact on women’s health and even life-threatening one of the most common malignant tumor. Rare male breast cancer.
Breast cancer is the breast epithelial cells in a variety of carcinogenic factor, the occurrence of a genetic mutation, resulting in uncontrolled cell proliferation. Because the biological behavior of cancer cells has changed, showing a disordered, unlimited malignant. Its histological form of a large number of naive unlimited proliferation of cancer cells and disorder-like crowding into a group, extrusion, and erosion and damage in the surrounding normal tissue, destroy normal breast tissue structure.
As the breast is not an important organ of human life and activity, in situ breast cancer from the theory, is not fatal, can be cured by surgical removal of method. But because breast cells lost after mutation of the characteristics of normal cells, tissue structural disorder, loosely connected cells, cancer cells can easily fall off free, such as blood or lymph systemic spread, the early formation of distant metastases to the breast cancer increased clinical cure very difficult. The transfer of the body of important organs such as lung metastases, brain metastases, bone metastases, all have direct threat to human life, so breast cancer is a serious life-threatening human malignant disease.
The principles of prevention and treatment of breast cancer with all the same, should strive for early detection and early treatment. In daily life, adhere to the scientific breast health, breast self-examination and regular examination of medical professionals is essential.
