ACTIVE NOT RECRUITING

NCT03448003

Comprehensive Lifestyle Change To Prevent Breast Cancer

This trial studies how well comprehensive lifestyle change works in preventing patients from breast cancer. A program including dietary recommendations, physical activity, stress management and mindfulness training, learning sleep hygiene techniques, and behavioral counseling in addition to social support may help patients who may be at risk for breast cancer.

Surgery in Preventing Ovarian Cancer in Patients With Genetic Mutations

This phase II trial studies how well surgery works in preventing ovarian cancer in patients with genetic mutations at risk of ovarian cancer. Risk reducing salpingo oophorectomy (RRSO) is surgery to remove the fallopian tubes and ovaries at the same time. Interval salpingectomy with delayed oophorectomy (ISDO) is surgery to remove the fallopian tubes. It is not known whether ISDO works better than RRSO at lowering risk of ovarian cancer and improving the sexual function and psychosocial well-being in patients with genetic mutation.

Progesterone and Muscle Protein Synthesis in Premenopausal Women (MP4-MPS)

The goal of this clinical trial is to learn if micronized progesterone (PROMETRIUM®) influences the muscle-building response to resistance exercise in healthy premenopausal women aged 18-30 years. The main questions it aims to answer are: 1. Does progesterone change the rate of muscle protein synthesis after exercise? 2. Does progesterone alter the difference in synthesis between an exercised leg and a rested leg? Researchers will compare micronized progesterone to a placebo to see if progesterone changes the way skeletal muscle adapts to resistance exercise. Participants will: * Take two oral doses of progesterone (400 mg total, 34 and 10 hours before testing) or placebo * Complete a unilateral leg extension exercise session in the lab * Receive an infusion of a stable isotope tracer and provide blood samples * Undergo muscle biopsies from the exercised and rested legs
