* Increased risk of breast CA with combined tx (0.8 add’l cases per 1000 pt-years)

Endometrial Cancer
* Known increase in risk with unopposed estrogen
* WHI showed no signif risk of CA with combined tx

Ovarian Cancer
* No overt correlation b/w combined HRT and ovarian CA risk
* There IS a signif risk reduction associated with OCPs

Colorectal Cancer
* Signif Risk Reduction of Colon CA with combined Est/Pro
* While less cases, trend toward worse prognosis (nodal spread)
* No risk reduction observed with estrogen alone

Osteoporosis
* Well established
* Risk reduced at hip, vertebrae, and wrist over placebo
