Breast

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. This syndrome presents as skin changes resembling eczema; such as redness, discoloration or mild flaking of the nipple skin. As Paget's disease of the breast advances, symptoms may include tingling, itching, increased sensitivity, burning, and pain. There may also be discharge from the nipple.

The breasts are divided by an invisible line running up and down and right to left through the nipple. Each of these 4 regions is called a quadrant. Most breast cancers develop in the upper outer quadrant of the breast, closest to the armpit. This is because this area has a lot of glandular tissue. Each breast lies over a large muscle called the pectoralis major muscle on the chest.

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. A number of cultures associate breasts with sexuality and tend to regard bare breasts in public as immodest or indecent. Breasts, especially the nipples, are an erogenous zone. A large number of colloquial terms for breasts are used in English, ranging from fairly polite terms to vulgar or slang. Humans are the only mammals whose breasts become permanently enlarged after sexual maturity known in humans as puberty. The reason for this evolutionary change is unknown. A link has been proposed to processes for synthesizing the endogenous steroid hormone precursor dehydroepiandrosterone which takes place in fat rich regions of the body like the buttocks and breasts. These contributed to human brain development and played a part in increasing brain size. Breast enlargement may for this purpose have occurred as early as Homo ergaster 1.
