What aspects of a womans body type might affect breast cancer risk?
Many studies have examined the association of different body types and breast cancer risk. Body type characteristics that have been examined are breast size, height, and a number of different features of body weight. The questions below will discuss the results of studies of body type and breast cancer risk. Does a woman’s breast size affect her breast cancer risk? Most studies have found no association between breast size and breast cancer risk. One carefully conducted study did find an increase in the risk of breast cancer among lean women with larger breasts. In this study, two thousand women were grouped according to their bra size before childbirth. Women who were lean (chest size less than 34 inches) and had larger breasts (size B or C cups) were at significantly higher risk of postmenopausal breast cancer relative to women of the same chest size with an A or smaller cup size. Women with other chest sizes had no association between breast size and breast cancer risk. More studies
