The term breast, also known by the Latin mamma in anatomy, refers to the upper ventral region of an animal's torso, particularly that of mammals, including human beings. In addition, the breasts are parts of a female mammal's body which contain the organs that secrete milk used to feed infants.
This article focuses on human female breasts, but it should be noted that male humans also have breasts (although usually less prominent) that are structurally identical and homologous to the female, as they develop embryologically from the same tissues. While the mammary glands that produce milk are present in the male, they normally remain undeveloped. In some situations male breast development does occur, a condition called gynecomastia. Milk production can also occur in both men and women as an adverse effect of some medicinal drugs (such as some antipsychotic medication), extreme physical stress or in endocrine disorders.

Secondhand Smoke -- Dr. Greene.com - Report on 1996 study: the relative risk for breast cancer from passive smoke (primarily girls whose parent smoked or women whose spouse smoked) was 3.2! This makes passive smoking a more important risk factor than having a mother with breast cancer (2.1), or having an early first period (1.3), or having a late first pregnancy (1.4).
