Breast Cancer

The breast is an exocrine gland that develops during the life of women. It contains the mammary glands which become active during periods of lactation to produce milk. In addition to breast feeding, the breast plays an important role in the shape and confidence of a woman. However, the breast is subject to many diseases, among which cancer.  

Breast cancer is a malignant tumor that develops in the mammary gland, more especially in the inner lining of the milk ducts. This condition occurs when abnormal cells, under the action of an external aggression or carcinogens (such as smoking or ultraviolet rays), multiply anarchically to form a malignant growth. Without a curative intervention, these malignant cells will continue to proliferate, and spread into other tissues in the body to form metastatic cancers; this condition is called metastatic breast cancer. Symptoms or characteristic of metastatic breast cancer depends greatly on the location of the secondary tumor.   

Although men are also victims of breast cancer, the disease is more common among women. It is estimated that about 1 woman out of 7 will be affected by breast cancer during their lifetime, which makes the disease the leading cause of death among gynecological cancers in developed countries.
