Finally, it is true that having no children also increases the risk of breast cancer, for two likely reasons: (1) The breasts never receive the benefit of a full - term pregnancy, which renders the breast tissue more mature and thus less susceptible to cancerous change; (2) The breasts are chronically stimulated with more cyclic surges of estradiol, without interruption by periods of pregnancy and lactation.
