Video: Treating breast cancer through surgery

Globally, 2.3 million women are diagnosed with breast cancer every year, according to the World Health Organization. Advances in treating breast cancer are improving care and quality of life.

Breast

The breast is the upper ventral region of the torso of a primate, in left and right sides, which in a female contains the mammary gland that secretes milk used to feed infants.

Both men and women develop breasts from the same embryological tissues. However, at puberty, female sex hormones, mainly estrogen, promote breast development which does not occur in men due to the higher level of testosterone. As a result, women's breasts become far more prominent than those of men.
