Epidemiologic data on the association between nonsteroidal antiinflammatory drugs (NSAIDs) and ovarian cancer risk have been inconsistent. The authors prospectively examined the association between...
Recreational Physical Activity and Steroid Hormone Levels in Postmenopausal Women (2009)
Bertone-Johnson, Elizabeth R., Tworoger, Shelley S., Hankinson, Susan E.
Recreational physical activity has been both positively and inversely associated with cancer risk for postmenopausal women, acting presumably through hormonal mechanisms. Relatively little is known...
Plasma Androgen Concentrations and Risk of Incident Ovarian Cancer (2008)
Tworoger, Shelley S., Lee, I-Min, Buring, Julie E., Hankinson, Susan E.
Androgens have been implicated in increasing ovarian cancer risk; however, results from prospective studies have been inconclusive. The authors examined whether plasma concentrations of testosterone,...
Tworoger, Shelley S., Fairfield, Kathleen M., Colditz, Graham A., Rosner, Bernard A., Hankinson, Susan E.

Eliassen, A. Heather, Missmer, Stacey A., Tworoger, Shelley S., Spiegelman, Donna, Barbieri, Robert L., Dowsett, Mitch, ...
Background: Higher levels of endogenous sex steroid hormones are associated with increased risks of breast cancer in postmenopausal women. Data for premenopausal women are sparse, in part because of...
Intake of Folate and Related Nutrients in Relation to Risk of Epithelial Ovarian Cancer (2006)
Tworoger, Shelley S., Hecht, Jonathan L., Giovannucci, Edward, Hankinson, Susan E.
Assessments of the relation between folate intake and ovarian cancer risk have been limited and inconsistent. Therefore, the authors prospectively examined the association of dietary and supplemental...
Tworoger, Shelley S., Missmer, Stacey A., Barbieri, Robert L., Willett, Walter C., Colditz, Graham A., Hankinson, Susan E.
Background: Sex hormone concentrations are associated with breast cancer risk among women not using postmenopausal hormones (PMH); however, whether a relationship exists among PMH users is unknown....
