Publisher Summary This chapter discusses breast carcinoma etiological factors. These factors seem to have a great influence on the incidence of breast cancer, but there is little agreement on which components of heritage are most important and the way they operate. Breast carcinoma is the most prevalent type of cancer in American women. Approximately 8% of American women can expect to be stricken with this disease some time during their lifetimes. The rate in men is 1% that in women. Although many etiological factors are implicated, the causes or reasons for a woman being afflicted with this disease remain equivocal. There is an abundance of evidence that the incidence of breast carcinoma varies greatly from one population to another throughout the world and that in most populations it is increasing. A woman's heritage is usually a large factor in determining her risk of developing mammary carcinoma. |
