Is there a link between estrogen and cancer?

Sharine Forbes

Hormone therapy for ovarian loss has been a topic of great interest for scientists for some time, as it has yielded both negative and positive results. Hormone therapy is a very controversial issue because estrogen has been proven to decrease the risk of osteoporosis, vaginitis and symptoms associated with menopause. It reduces the risk of osteoporosis because the presence of estrogen can slow down bone mineral loss. Conversely, it has been linked to increase the risk of certain cancers, like breast and uterine cancer, and even increase the risk of cardiovascular disease. It increases the risk of uterine cancer by causing a buildup of uterine tissue. It increases the risk of breast cancer as it causes the breast tissue to grow. Furthermore, estrogen therapy has been linked to adversely affect soluble plasma glycoprotein, plasma viscosity, and insulin sensitivity, along with endothelial cell activation.
