Experimental: CA 125 Analysis
Participants will have blood (about 2-3 tablespoons) drawn for CA-125 testing and other tumor markers. Depending on CA-125 level: Blood (about 2-3 tablespoons) drawn for CA-125 testing and other tumor markers in 1 year. Blood (about 2-3 tablespoons) drawn for CA-125 testing and other tumor markers in 3 months, OR Blood (about 2-3 tablespoons) drawn for CA-125 testing and other tumor markers, and a transvaginal ultrasound in 6 weeks +/- 2 weeks. Questionnaires completed at baseline and during each follow up visit. |
Behavioral: Questionnaire
Questionnaires completed at baseline and during each follow up visit.
Other Name: Survey |
- Rate of increase in CA 125 levels over time [ Time Frame: Based on CA-125 level, 3 options will result: 1) re-draw blood (CA-125) in 1 year, 2) re-draw blood (CA-125) in 3 months), or 3) re-draw blood (CA-125) AND TVUS in 6 weeks +/- 2 weeks. ]
