Breast

The breast is one of two prominences located on the upper ventral region of a primate 's torso. Both females and males develop breasts from the same embryological tissues. In females, it serves as the mammary gland , which produces and secretes milk to feed infants. At the ends of the ducts are lobules , or clusters of alveoli , where milk is produced and stored in response to hormonal signals. Humans are the only animals with permanent breasts. At puberty , estrogens, in conjunction with growth hormone , cause permanent breast growth in female humans. This happens only to a much lesser extent in other primates—breast development in other primates generally only occurs with pregnancy. Along with their major function in providing nutrition for infants, female breasts have social and sexual characteristics. Breasts have been featured in ancient and modern sculpture, art, and photography. They can figure prominently in the perception of a woman's body and sexual attractiveness.

Breast cancer is a cancer that develops from breast tissue. Risk factors for developing breast cancer include obesity , a lack of physical exercise , alcohol consumption, hormone replacement therapy during menopause , ionizing radiation , an early age at first menstruation , having children late in life or not at all, older age, having a prior history of breast cancer, and a family history of breast cancer. The balance of benefits versus harms of breast cancer screening is controversial. A Cochrane review found that it was unclear if mammographic screening does more harm than good, in that a large proportion of women who test positive turn out not to have the disease. Outcomes for breast cancer vary depending on the cancer type, the extent of disease , and the person's age. Most people with breast cancer have no symptoms at the time of diagnosis; their tumor is detected by a breast cancer screening test. Lumps found in lymph nodes located in the armpits [20] may also indicate breast cancer. Another symptom complex of breast cancer is Paget's disease of the breast.
